Evaluators implement the ``Evaluator`` interface, register themselves with the handler registry, and are dynamically loaded at runtime via environment variables. + +Example: deepeval integration +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +The `deepeval` package provides a rich suite of LLM quality metrics (relevance, bias, hallucination, toxicity, etc.). To install and enable the deepeval evaluator: + +.. code-block:: bash + + # Install the core utilities with deepeval support + pip install opentelemetry-util-genai[deepeval] + + # Enable evaluation and select the deepeval evaluator + export OTEL_INSTRUMENTATION_GENAI_EVALUATION_ENABLE=true + export OTEL_INSTRUMENTATION_GENAI_EVALUATORS=deepeval + +At runtime, after you start and stop your LLM invocation, call: + +.. code-block:: python + + from opentelemetry.util.genai.handler import get_telemetry_handler + + handler = get_telemetry_handler() + # ... run your invocation lifecycle (start_llm, provider call, stop_llm) ... + results = handler.evaluate_llm(invocation) + for eval_result in results: + print(f"{eval_result.metric_name}: {eval_result.score} ({eval_result.label})") + +Beyond deepeval, you can create or install other evaluator packages by implementing the ``Evaluator`` interface and registering with the GenAI utilities registry. The handler will load any evaluators listed in ``OTEL_INSTRUMENTATION_GENAI_EVALUATORS``. + +Threading / Concurrency +----------------------- +* A singleton handler is typical; OpenTelemetry SDK manages concurrency. +* Do **not** reuse an ``LLMInvocation`` instance across requests. + +Stability Disclaimer +-------------------- +GenAI semantic conventions are incubating; attribute names & enabling conditions may change. Track the project CHANGELOG & release notes. + +Troubleshooting +--------------- +* **Span missing message content**: + * Ensure experimental stability + capture env var set *before* ``start_llm``. + * Verify messages placed in ``input_messages``. +* **No spans exported**: + * Confirm a ``TracerProvider`` is configured and set globally. + +Roadmap (Indicative) +-------------------- +* Configurable generator selection (env / handler param) +* Metrics stabilization (token counts & durations) via ``SpanMetricGenerator`` +* Event emission (choice logs) maturity & stabilization +* Enhanced tool call structured representation + +Minimal End-to-End Test Snippet +-------------------------------- +.. code-block:: python + + from opentelemetry.sdk.trace import TracerProvider + from opentelemetry.sdk.trace.export import SimpleSpanProcessor, InMemorySpanExporter + from opentelemetry import trace + + exporter = InMemorySpanExporter() + provider = TracerProvider() + provider.add_span_processor(SimpleSpanProcessor(exporter)) + trace.set_tracer_provider(provider) + + from opentelemetry.util.genai.handler import get_telemetry_handler + from opentelemetry.util.genai.types import LLMInvocation, InputMessage, OutputMessage, Text + + handler = get_telemetry_handler() + inv = LLMInvocation( + request_model="demo-model", + provider="demo-provider", + input_messages=[InputMessage(role="user", parts=[Text(content="ping")])], + ) + handler.start_llm(inv) + inv.output_messages = [OutputMessage(role="assistant", parts=[Text(content="pong")], finish_reason="stop")] + handler.stop_llm(inv) + + spans = exporter.get_finished_spans() + assert spans and spans[0].name == "chat demo-model" + +License +------- +See parent repository LICENSE (Apache 2.0 unless otherwise stated). diff --git a/util/opentelemetry-util-genai-dev/pyproject.toml b/util/opentelemetry-util-genai-dev/pyproject.toml new file mode 100644 index 0000000000..a447bc1824 --- /dev/null +++ b/util/opentelemetry-util-genai-dev/pyproject.toml @@ -0,0 +1,54 @@ +[build-system] +requires = ["hatchling"] +build-backend = "hatchling.build" + +[project] +name = "opentelemetry-util-genai" +dynamic = ["version"] +description = "OpenTelemetry GenAI Utils" +readme = "README.rst" +license = "Apache-2.0" +requires-python = ">=3.9" +authors = [ + { name = "OpenTelemetry Authors", email = "cncf-opentelemetry-contributors@lists.cncf.io" }, +] +classifiers = [ + "Development Status :: 4 - Beta", + "Intended Audience :: Developers", + "License :: OSI Approved :: Apache Software License", + "Programming Language :: Python", + "Programming Language :: Python :: 3", + "Programming Language :: Python :: 3.9", + "Programming Language :: Python :: 3.10", + "Programming Language :: Python :: 3.11", + "Programming Language :: Python :: 3.12", + "Programming Language :: Python :: 3.13", +] +dependencies = [ + "opentelemetry-instrumentation ~= 0.57b0", + "opentelemetry-semantic-conventions ~= 0.57b0", + "opentelemetry-api>=1.31.0", +] + +[project.entry-points.opentelemetry_genai_upload_hook] +fsspec = "opentelemetry.util.genai._fsspec_upload:fsspec_upload_hook" + +[project.optional-dependencies] +test = ["pytest>=7.0.0"] +fsspec = ["fsspec>=2025.9.0"] + +[project.urls] +Homepage = "https://github.com/open-telemetry/opentelemetry-python-contrib/tree/main/util/opentelemetry-util-genai" +Repository = "https://github.com/open-telemetry/opentelemetry-python-contrib" + +[tool.hatch.version] +path = "src/opentelemetry/util/genai/version.py" + +[tool.hatch.build.targets.sdist] +include = [ + "/src", + "/tests", +] + +[tool.hatch.build.targets.wheel] +packages = ["src/opentelemetry"] diff --git a/util/opentelemetry-util-genai-dev/src/opentelemetry/util/genai/__init__.py b/util/opentelemetry-util-genai-dev/src/opentelemetry/util/genai/__init__.py new file mode 100644 index 0000000000..b0a6f42841 --- /dev/null +++ b/util/opentelemetry-util-genai-dev/src/opentelemetry/util/genai/__init__.py @@ -0,0 +1,13 @@ +# Copyright The OpenTelemetry Authors +# +# Licensed under the Apache License, Version 2.0 (the "License");

+## 1. Purpose +This document analyzes differences between the Traceloop `opentelemetry-instrumentation-langchain` implementation ("Traceloop version") and the current upstream development package `opentelemetry-instrumentation-langchain-dev` ("Dev version"), and proposes a phased plan to close functionality gaps by leveraging / extending `opentelemetry-util-genai-dev`. + +It also answers: Should we copy the entire Traceloop package first, or incrementally evolve the Dev version? And: What new concepts must be added to `opentelemetry-util-genai-dev` to support feature parity cleanly? + +--- +## 2. High-Level Summary +The Traceloop version implements a rich, hierarchical span model (workflow → task → LLM/tool), prompt/response capture (attributes or events), tool call recording, token & duration metrics, vendor/model detection heuristics, and robust error context management. The Dev version currently creates *only one* LLM invocation span per `on_chat_model_start` → `on_llm_end/error` lifecycle and relies on `opentelemetry-util-genai-dev` for span + metrics emission. + +`opentelemetry-util-genai-dev` already supports: +- Generic lifecycle management for LLM/Embedding/ToolCall invocations +- Unified span + metrics + optional content event generation +- Evaluation (length/sentiment, optional DeepEval) post-completion + +It does **not yet** offer explicit primitives for: workflows / chains / tasks, entity path composition, structured function/tool definition attributes (semconv-aligned), per-generation multi-choice output modeling, hierarchical run_id propagation semantics beyond existing `parent_run_id` storage, or streaming chunk events. + +--- +## 3.

Some original Traceloop logic (hierarchical workflow / task / LLM spans and attribute conventions) is now commented out in: + +`instrumentation-genai/opentelemetry-instrumentation-langchain-dev/src/opentelemetry/instrumentation/langchain/callback_handler.py` + +Specifically inside: +- `on_chat_model_start` (original span creation commented) +- `on_llm_end` (original span finalization + usage attribution commented) + +We will introduce a new emitter (e.g. `TraceloopCompatEmitter`) that can generate spans matching the *LLM span layer* semantics (naming + attributes) and optionally re-enable hierarchical spans for workflows/tasks if feasible with minimal callback modifications. + +## Constraints & Design Principles +1. **Pluggable via env var** – Reuse `OTEL_INSTRUMENTATION_GENAI_EMITTERS`; add a new accepted token (proposal: `traceloop_compat`). +2. **Non-invasive** – Avoid large rewrites of `TelemetryHandler`; implement the emitter as an additional concrete emitter class living under `util/opentelemetry-util-genai-dev/src/opentelemetry/util/genai/emitters/`. +3. **Graceful coexistence** – Allow combinations (e.g. `span_metric,traceloop_compat`) where Traceloop spans are produced alongside semconv spans (document implications / duplication risk). +4. **Backward-compatible naming** – Use span names & attributes patterned after original code (`.` for LLM spans, `workflow_name.task`, etc.). +5. **Trace shape** – If full hierarchy cannot be reproduced with only the current utility handler interface, provide at least equivalent LLM span attributes; optionally add a light modification to callback handler to emit workflow/task spans *only when env var is enabled*. +6. **Fail-safe** – If emitter misconfigured / errors, fallback silently to existing emitters (never break primary telemetry path). + +## Current Architecture Overview (for Agent Reference) +Relevant directories/files: + +| Purpose | Path | +|---------|------| +| Dev callback handler | `instrumentation-genai/opentelemetry-instrumentation-langchain-dev/src/opentelemetry/instrumentation/langchain/callback_handler.py` | +| Traceloop original reference | `traceloop/openllmetry/packages/opentelemetry-instrumentation-langchain/opentelemetry/instrumentation/langchain/callback_handler.py` | +| Util emitters package | `util/opentelemetry-util-genai-dev/src/opentelemetry/util/genai/emitters/` | +| Existing emitters | `span.py`, `metrics.py`, `content_events.py`, `composite.py` | +| Telemetry handler | `util/opentelemetry-util-genai-dev/src/opentelemetry/util/genai/handler.py` | +| Env vars constants | `util/opentelemetry-util-genai-dev/src/opentelemetry/util/genai/environment_variables.py` | +| Env parsing | `util/opentelemetry-util-genai-dev/src/opentelemetry/util/genai/config.py` | +| Types (LLMInvocation, messages) | `util/opentelemetry-util-genai-dev/src/opentelemetry/util/genai/types.py` | +| Span attribute helpers (Traceloop) | `instrumentation-genai/.../span_utils.py` (already imported) | + +## Extracted (Commented) Dev Handler Snippets +`on_chat_model_start` (current code uses util handler;

Need to decide using invocation attributes; may pass `original_callback_name` in `LLMInvocation.attributes`. + - Adds Traceloop-compatible attributes (entity/workflow names if provided). + - Optionally supports hierarchical spans if caller supplies parent context (stretch goal – Phase 2). +2. **Environment Variable Extension**: + - Extend `OTEL_INSTRUMENTATION_GENAI_EMITTERS` accepted values with `traceloop_compat`. + - Parsing logic: if list contains `traceloop_compat`, append the new emitter to composed list (order after standard span emitter by default so traces include both styles or allow only traceloop when specified alone). +3. **Callback Handler Conditional Path**: + - Add a lightweight feature flag check (e.g., inspect env once) to decide whether to: + a. Keep current util-only flow (default), or + b. Also populate Traceloop-specific runtime context (e.g., inject `original_callback_name` attribute into the `UtilLLMInvocation.attributes`). + - Avoid reintroducing the full original span logic inside the handler; emitter should derive everything from enriched invocation. +4. **Invocation Attribute Enrichment**: + - During `on_chat_model_start`, when traceloop compat flag is active: + - Add keys: + - `traceloop.entity.name` (the callback name) + - `traceloop.workflow.name` (root chain name if determinable – may need small bookkeeping dictionary for run_id→workflow, replicating existing `self.spans` logic minimally or reuse `self.spans` holder already present). + - `traceloop.span.kind` = `llm` for the LLM span (workflow/task spans Phase 2). + - Raw inputs (if content capture enabled and events not used) aggregated into `traceloop.entity.input`. + - On `on_llm_end` add similar output attributes (`traceloop.entity.output`) & usage if available. +5. **Metrics**: Continue using existing `MetricsEmitter`; no changes required (it already records duration + tokens). +6. **Content Capture**: Respect existing content capture mode env var; avoid duplicating message content on both traceloop and semconv spans simultaneously unless user explicitly chooses combined configuration. +7. **Documentation**: Add markdown doc (this file) plus update `environment_variables.py` docstring for new enum value and add a README blurb under `instrumentation-genai/opentelemetry-instrumentation-langchain-dev/docs/` (Phase 2). + +## Implementation Phases +### Phase 1 (MVP – This Request Scope) +- [ ] Add new emitter class (LLM span only, no workflow/task hierarchy) producing Traceloop attribute keys & span naming. +- [ ] Add env var token handling (`traceloop_compat`). +- [ ] Inject minimal extra attributes in callback handler when flag active. +- [ ] Unit tests validating span name + key attributes presence. +- [ ] Update docs & changelog stub. + +### Phase 2 (Optional / Future) +- Reintroduce workflow/task span hierarchy using a small state manager storing run_id relationships (mirroring old `self.spans` but only for naming + parent spans in compat mode). +- Emit tool call spans via either existing ToolCall start/stop or additional callback hooks. +- Add option to disable semconv span when traceloop compat is enabled alone (controlled by specifying ONLY `traceloop_compat` in env). + +## Detailed Task Breakdown for Coding Agent +1. Parse Env Support + - File: `util/opentelemetry-util-genai-dev/src/opentelemetry/util/genai/config.py` + - Accept new token: if `gen_choice` contains `traceloop_compat` (comma-separated handling needed – currently single value). Adjust parsing to split list (today it treats as single). Option A: extend semantics so variable may be comma-separated; interpret first token as base flavor (span/span_metric/span_metric_event) and additional tokens as augmenting emitters. + - Provide structured result: perhaps store an `extra_emitters: list[str]` field; **OR** (simpler) keep original fields and add a new function in handler to interrogate raw env string. + - File: `environment_variables.py` – update docstring for `OTEL_INSTRUMENTATION_GENAI_EMITTERS` to mention `traceloop_compat`. +2. New Emitter + - File: `util/opentelemetry-util-genai-dev/src/opentelemetry/util/genai/emitters/traceloop_compat.py` + - Class `TraceloopCompatEmitter` with same interface (`start`, `finish`, `error`, `handles`). + - On `start(LLMInvocation)`: + - Determine span name: prefer `invocation.attributes.get("traceloop.callback_name")` else `f"{invocation.request_model}.chat"` or `f"chat {invocation.request_model}"` (decide consistent naming – original used `.`; supply `.chat`). + - Start CLIENT span, set attributes: + - `traceloop.span.kind = "llm"` + - `traceloop.workflow.name` if present in attributes + - `traceloop.entity.name` / `traceloop.entity.path` + - Store raw inputs if `capture_content` and attribute key not suppressed. + - Semconv attributes already added by `SpanEmitter`; to avoid duplication, optionally skip semconv span if configuration instructs (Phase 2). Initially we let both exist. + - On `finish`: set outputs, usage (input/output tokens already on invocation), and `gen_ai.response.id` if available. + - On `error`: set status and same final attributes. + - Register export in `emitters/__init__.py` (optional if imported directly by handler). +3. TelemetryHandler Wiring + - File: `handler.py` + - After constructing base emitters list, check env raw string or `settings` for presence of `traceloop_compat`. + - If present, import and append `TraceloopCompatEmitter` instance (respect appropriate capture flags – may use span-only content capturing mode or its own internal flag mirroring `SpanEmitter`). +4. Callback Handler Adjustments + - File: `instrumentation-genai/.../callback_handler.py` + - Introduce a module-level lazy boolean `_TRACELOOP_COMPAT_ENABLED` evaluating env once (`os.getenv("OTEL_INSTRUMENTATION_GENAI_EMITTERS", "").lower()` contains `traceloop_compat`). + - In `on_chat_model_start` before creating `UtilLLMInvocation`, compute `callback_name = self._get_name_from_callback(serialized, kwargs=kwargs)` and if compat enabled add: + ```python + attrs["traceloop.callback_name"] = callback_name + attrs["traceloop.span.kind"] = "llm" + # For Phase 2, optionally add workflow/entity placeholders + ``` + - In `on_llm_end` after tokens & content resolution, if compat enabled add: + ```python + if inv.output_messages: + inv.attributes["traceloop.entity.output"] = json.dumps([m.__dict__ for m in inv.output_messages]) + if inv.input_messages: + inv.attributes.setdefault("traceloop.entity.input", json.dumps([m.__dict__ for m in inv.input_messages])) + if inv.response_id: + inv.attributes["gen_ai.response.id"] = inv.response_id + ``` + - (DON'T resurrect old span logic here; emitter will consume these attributes.) +5. Tests + - Location: `util/opentelemetry-util-genai-dev/tests/` (create new test file `test_traceloop_compat_emitter.py`). + - Cases: + 1. Enabling env var yields additional span with expected name `.chat` and attributes present. + 2. Without env var, no traceloop attributes appear on emitted semconv span. + 3. Token usage still recorded exactly once (metrics unaffected). + 4. Error path sets error status. + - Use in-memory span exporter to capture spans and assert counts & attribute keys. +6. Documentation Updates + - This plan file committed. + - Add bullet to `langchain_instrumentation_gap_analysis.md` referencing traceloop compat emitter availability. + - Extend env var docs in `environment_variables.py`. +7. Changelog Stub + - Add entry in root or instrumentation package CHANGELOG (depending on repo practice) noting new `traceloop_compat` emitter. + +## Risks & Mitigations +| Risk | Mitigation | +|------|------------| +| Duplicate spans increase cost | Document clearly; allow users to specify ONLY `traceloop_compat` to suppress standard span emitter in Phase 2. | +| Attribute name collisions | Prefix all custom keys with `traceloop.` (as original). | +| Performance overhead | Lightweight; optional path only when env var present. | +| Future removal of Traceloop custom attributes | Isolated in one emitter; easy deprecation path. | + +## Open Questions (Flag for Maintainers) +1. Should `traceloop_compat` suppress the default semconv span automatically when used alone? (Recommend: yes – document expectation.) +2. Do we need hierarchical workflow/task spans for MVP? (Recommend: defer; collect feedback.) +3. Should we map `traceloop.span.kind` to semconv `gen_ai.operation.name` or keep separate? (Keep separate for purity.) + +## Acceptance Criteria (Phase 1) +- Env var `OTEL_INSTRUMENTATION_GENAI_EMITTERS=traceloop_compat` produces one span per LLM invocation named `.chat` with Traceloop attribute keys. +- Combined config `OTEL_INSTRUMENTATION_GENAI_EMITTERS=span_metric,traceloop_compat` produces both semconv span + traceloop compat span. +- No uncaught exceptions when flag enabled/disabled. +- Existing tests pass; new tests validate emitter behavior. + +## Example Environment Configurations +| Desired Output | Env Setting | +|----------------|------------| +| Standard spans only (current default) | (unset) or `span` | +| Standard spans + metrics | `span_metric` | +| Standard spans + metrics + content events | `span_metric_event` | +| Traceloop compat only | `traceloop_compat` | +| Standard span + traceloop compat | `span,traceloop_compat` | +| Standard full (span+metric+events) + traceloop | `span_metric_event,traceloop_compat` | + +(Note: Parsing update must allow comma-separated tokens.) + +## Pseudocode Illustrations +### Emitter Skeleton +```python +class TraceloopCompatEmitter: + role = "traceloop_compat" + name = "traceloop_compat_span" + + def __init__(self, tracer=None, capture_content=False): + self._tracer = tracer or trace.get_tracer(__name__) + self._capture_content = capture_content + + def handles(self, obj): + return isinstance(obj, LLMInvocation) + + def start(self, invocation: LLMInvocation): + cb_name = invocation.attributes.get("traceloop.callback_name") or invocation.request_model or "unknown" + span_name = f"{cb_name}.chat" + cm = self._tracer.start_as_current_span(span_name, kind=SpanKind.CLIENT, end_on_exit=False) + span = cm.__enter__() + invocation.attributes.setdefault("traceloop.span.kind", "llm") + for k, v in invocation.attributes.items(): + if k.startswith("traceloop."): + span.set_attribute(k, v) + if self._capture_content and invocation.input_messages: + span.set_attribute("traceloop.entity.input", json.dumps([asdict(m) for m in invocation.input_messages])) + invocation.__dict__["traceloop_span"] = span + invocation.__dict__["traceloop_cm"] = cm + + def finish(self, invocation: LLMInvocation): + span = getattr(invocation, "traceloop_span", None) + cm = getattr(invocation, "traceloop_cm", None) + if not span: + return + if self._capture_content and invocation.output_messages: + span.set_attribute("traceloop.entity.output", json.dumps([asdict(m) for m in invocation.output_messages])) + if invocation.response_id: + span.set_attribute(GEN_AI_RESPONSE_ID, invocation.response_id) + if cm and hasattr(cm, "__exit__"): + cm.__exit__(None, None, None) + span.end() + + def error(self, error: Error, invocation: LLMInvocation): + span = getattr(invocation, "traceloop_span", None) + cm = getattr(invocation, "traceloop_cm", None) + if not span: + return + span.set_status(Status(StatusCode.ERROR, error.message)) + if cm and hasattr(cm, "__exit__"): + cm.__exit__(None, None, None) + span.end() +``` + +### Handler Integration (Snippet) +```python +raw = os.getenv(OTEL_INSTRUMENTATION_GENAI_EMITTERS, "span") +tokens = [t.strip().lower() for t in raw.split(',') if t.strip()] +base = next((t for t in tokens if t in {"span", "span_metric", "span_metric_event"}), "span") +extra = [t for t in tokens if t not in {base}] +# existing logic picks base -> emitters list +if "traceloop_compat" in extra: + from .emitters.traceloop_compat import TraceloopCompatEmitter + emitters.append(TraceloopCompatEmitter(tracer=self._tracer, capture_content=capture_span or capture_events)) +``` + +### Callback Attribute Enrichment +```python +if _TRACELOOP_COMPAT_ENABLED: + callback_name = self._get_name_from_callback(serialized, kwargs=kwargs) + attrs["traceloop.callback_name"] = callback_name + attrs.setdefault("traceloop.span.kind", "llm") +``` + +## Test Assertion Examples +```python +# After running a simple Chat model invocation with traceloop_compat only: +spans = exporter.get_finished_spans() +assert any(s.name.endswith('.chat') and 'traceloop.span.kind' in s.attributes for s in spans) +``` + +## Rollback Strategy +All changes are additive behind an env flag; rollback is simply removing the emitter file and references.

High-Level Assessment +Your strategic goals (decoupling instrumentation from emission, supporting multiple telemetry "flavors", enabling evaluators, and backward compatibility) are solid. The main risk is over-expanding class hierarchies and package fragmentation before real divergence of behavior justifies them. + +Lean principle: Keep the core minimal, composable, and data‑model centric; add layers only once ≥2 concrete implementations demand differentiation. + +## 2. Current vs Proposed +Current implementation: A simple `SpanGenerator` plus a handler that creates spans for `LLMInvocation`. This is easy to maintain and fast to evolve. + +Proposed design introduces: +- Deep inheritance: `BaseGenerator` → `BaseSpanGenerator` → `LLMInvocationSpanGenerator`, etc. +- Per GenAI type × per telemetry type classes (Cartesian growth). +- Multiple packages for generators, evaluators, decorators, translators early. +- Separate handlers per data type. + +Risk: Boilerplate explosion, slower iteration during a still-moving semantic conventions (semconv) phase. + +## 3. Recommended Lean Core (MVP) +Core building blocks to stabilize first: +1. Data types (`LLMInvocation`, `EmbeddingInvocation`, `ToolCall`, `EvaluationResult`, `Error`) as plain dataclasses / pydantic-lite (no telemetry logic inside). +2. A single `Generator` protocol: `start(obj)`, `finish(obj)`, `error(obj, err)`. +3. `CompositeGenerator` that fans out calls to a list of emitters (SpanEmitter, MetricEmitter, EventEmitter) — composition over inheritance. +4. One `TelemetryHandler` orchestrating lifecycle + env-based configuration + optional evaluation triggering. +5. `Evaluator` protocol: `evaluate(obj) -> list[EvaluationResult]`. +6. Optional plugin discovery via entry points (defer actual external packages until needed). + +## 4. What to Defer (Premature / Overengineered Now) +| Area | Why Defer | Lean Alternative | +|------|-----------|------------------| +| Deep inheritance tree of Base* classes | Adds cognitive load without behavior differences | Flat protocol + small emitters | +| Per telemetry type + per GenAI type classes | Creates boilerplate (Span+Metric+Event × N types) | Single emitter branches on `isinstance` | +| Multiple packages (traceloop, splunk, decorators) now | Release & version coordination overhead | Keep in-core or external after API stabilizes | +| Hooks `_on_before_* / _on_after_*` | YAGNI until cross-cutting concerns exist | Add a middleware list later | +| Separate handlers (LLMInvocationTelemetryHandler, etc.) | API surface bloat | Single handler + optional convenience wrappers | +| Dedicated evaluation handler | Duplicates lifecycle logic | Use existing handler post-finish phase | + +## 5. Env & Config Suggestions +Simplify and future-proof variable names: +- `OTEL_GENAI_FLAVOR=span|span_metrics|span_metrics_events` +- `OTEL_GENAI_CAPTURE_CONTENT=none|input|input_output|full` +- `OTEL_GENAI_EVALUATORS=deepeval,ragas` +- `OTEL_GENAI_EXPERIMENTAL_ATTRS=1` (gate non-stable attrs) + +Keep parsing centralized (single config object) so new strategies don’t scatter env lookups. + +## 6. Semantic Conventions Strategy +- Pin semconv version explicitly and expose via `get_semconv_version()`. +- Maintain a mapping module for attribute names (avoid spreading literals) — easier churn handling. +- Introduce feature flag for experimental attributes. +- Document attribute changes per release (ADD / RENAME / DEPRECATE table). + +## 7. Evaluation Architecture Guidance +Lifecycle: +``` +start(invocation) +... user action ... +finish(invocation) +if evaluations enabled: + for ev in evaluators: + results = ev.evaluate(invocation) + for r in results: + generator.start(r); generator.finish(r) +``` +No need for a separate evaluation handler unless you require streaming or asynchronous batching. + +## 8. Decorators Layer +Keep decorators lightweight sugar around building domain objects and calling the handler. Defer publishing a dedicated decorators package until patterns stabilize. Provide a helper like: +`wrap_llm_call(fn, handler, model=..., capture_input=True, capture_output=True)`. + +## 9. Backward Compatibility (Traceloop) +Use an adapter pattern: +- `TraceloopAdapter(traceloop_obj) -> LLMInvocation` +Then feed into existing handler & generators. Avoid special generator subclasses early. + +## 10. Plugin / Extension Loading +Phase-in plan: +- Phase 1: Hard-coded internal emitters. +- Phase 2: Entry point discovery (e.g., `opentelemetry_genai.generators`). +- Phase 3: External plugin packages once at least one real consumer emerges. + +## 11. Versioning & Stability Signaling +- Expose `__telemetry_api_version__` in package root. +- Emit a one-time warning if API labeled experimental (suppressible by env var). +- Provide clear upgrade notes with attribute diffs. + +## 12. Decision Heuristics (Litmus Test) +Before adding a new abstraction ask: +1. Does it remove duplication across ≥2 concrete implementations NOW? +2. Is there an external request that needs this seam? +3. Will removing it later be a breaking change? (If yes, keep it out until confidence is higher.) + +If answers: (No / Not yet / Yes) → Defer. + +## 13.

Immediate Actionable Steps +1. Add a `CompositeGenerator` (even if wrapping one span emitter today) to future-proof API without inheritance commitment. +2. Centralize environment parsing into a `config.py` returning a frozen settings object. +3. Introduce `Evaluator` protocol + stub implementation (returns empty list) to anchor extension surface. +4. Consolidate span attribute name mapping in one module (reduces churn risk). +5. Write an ADR: "Adopt composition for GenAI telemetry generation; defer deep subclassing." and link to this feedback. +6. Refactor existing handler (if multiple) into a single orchestrator with type-dispatch table (optional convenience wrappers remain). + +## 16. What NOT To Implement Yet +- `BaseMetricGenerator`, `BaseEventGenerator` with placeholder hooks. +- Separate handler classes per GenAI type. +- Multi-package external splits (deepeval, splunk) until extension API is proven. +- Hook lattice (`_on_before_*`)—substitute later with a simple middleware list if needed. + +## 17. Summary +Proceed with a minimal, composable core (data types + single composite generator + handler + evaluator protocol).

Testing Strategy +- Unit tests per flavor verifying emission distribution. +- Plugin resolution tests with mock entry points (pkg_resources/importlib.metadata). +- Ordering tests using a probe emitter recording sequence. +- Context tests verifying active span during metric/event emission. +- Evaluation aggregation tests for Splunk plugin simulation. +- Error path tests verifying no metrics/events on failure. + +## 11. Migration Notes +- Existing users: no code changes; default flavor = `span` (backward compatible). +- Setting `OTEL_GENAI_FLAVOR=span_metric_event` automatically moves content off span into events. +- Traceloop adopts plugin path; instruct users to set either `OTEL_GENAI_PLUGIN_OVERRIDES=span:traceloop` or `OTEL_GENAI_SPAN_VENDOR=traceloop`. + +## 12. Open Questions +- Should evaluation metrics also become OTel metrics? (Planned but can be gated by feature flag later.) +- Standardized hashing algorithm for content summaries?

Goals +| Goal | Description | +|------|-------------| +| G1 | Single orchestration path for all GenAI object emissions. | +| G2 | Remove `generators/*` concrete classes (retain thin compatibility shim temporarily). | +| G3 | Central ordering guarantees (span open for dependent emissions). | +| G4 | Flavor-based composition (span, span+metric, span+metric+event). | +| G5 | Extensible via entry point plugins (emitters & evaluators). | +| G6 | Traceloop: spans only + vendor attrs; still semconv-compliant. | +| G7 | Splunk: aggregated evaluation result event replaces default strategy. | +| G8 | Backward compatibility for current handler API. | +| G9 | Clear testing matrix & acceptance criteria. | + +## 4.

Documentation Updates +- README: new section "Telemetry Flavors & Content Capture". +- Plugin author guide: roles, override semantics, minimal skeleton. +- FEEDBACK.md: link to ADR 0002 for final direction. + +## 16.

subscribers react. +```python +bus.emit('invocation.start', obj=inv) +bus.emit('invocation.finish', obj=inv) +``` +Pros: Maximum decoupling. +Cons: Ordering and conflicts require additional policy. + +--- +## Option 5: Hook Set (pytest-like) +Named hooks;

Describes the *target* design (not current PoC state). Backward compatibility is **not** a constraint for this refactor branch. + +## 1. Goals (Why this utility exists) +Provide a stable, extensible core abstraction (GenAI Types + Handler + Emitters + Evaluator hooks) separating *instrumentation capture* from *telemetry flavor emission* so that: +- Instrumentation authors emit neutral GenAI data types once. +- Different telemetry “flavors” (OpenTelemetry semantic convention variants, vendor-specific enrichments, custom schemas, events vs span attributes, aggregated evaluation result events, cost metrics, etc.) are produced by pluggable emitters without changing instrumentation. +- Evaluations (LLM-as-a-judge, quality metrics) run asynchronously and re-emit results through the same unified Handler/Emitter pipeline. +- Third parties can add / replace / augment emitters in well-defined lifecycle insertion points with minimal coupling. +- Configuration happens via consistent environment variables; defaults are sensible; complexity is opt-in. + +Non-goal: Reinvent the OpenTelemetry SDK export pipeline; emitters sit *above* the SDK using existing Span / Metric / Log / Event APIs. + +## 2. Core Concepts +### 2.1 GenAI Types (Data Model) +Neutral, in-memory domain objects capturing invocation lifecycle independent of final telemetry encoding. Envisioned (extensible) set: +- `LLMInvocation` +- `AgentInvocation` +- `RetrievalInvocation` +- `EmbeddingInvocation` +- `WorkflowInvocation` +- `StepInvocation` +- `PlannerInvocation` +- `EvaluationResults` (represents a batch/list of individual `EvaluationResult` objects aggregated by evaluator logic or raw single result when not aggregated) + +Common base shape (conceptual): +``` +GenAIInvocation: + id: str (stable unique id – UUID or deterministic) + parent_id: Optional[str] + span_context: CapturedSpanContext (snapshot at creation) + start_time_ns: int + end_time_ns: Optional[int] + model/provider/tool identifiers (type-specific fields) + input_messages: List[Message] + output_messages: List[Message] + system_messages: List[Message] + tokens_prompt / tokens_completion / cost metrics (optional collected or provided later) + attributes: MutableMapping[str, Any] (extensible metadata) +``` +Messages hold role, content (structured parts), and optional metadata. + +`EvaluationResult` (atomic) includes: metric_name, value (numeric or categorical), pass_fail (optional bool), confidence(optional), reasoning(optional), latency(optional), additional_attrs. + +### 2.2 Handler +`Handler` is the façade used by instrumentation and evaluators. Responsibilities: +- Construct GenAI Types (factory helpers) capturing span context immediately (even if spans later suppressed or not emitted). +- Provide lifecycle methods: `start_*(invocation)` and `end_*(invocation)` OR a high-level context manager convenience. +- Delegate to a `CompositeEmitter` for actual telemetry emission at well-defined lifecycle points. +- Offer `evaluation_results(results: EvaluationResults)` for evaluators. +- Maintain optional registry of completion callbacks (e.g., Evaluation Manager) implementing `CompletionCallback.on_completion(gen_ai_invocation)`. + +### 2.3 Span Context Capture +When a GenAI Type is instantiated, the active span (if any) is queried and encoded into a lightweight `CapturedSpanContext` containing trace_id, span_id, trace_flags, trace_state. This allows metrics/events emitters to correlate even if span emission is disabled. + +## 3. Emitter Architecture +### 3.1 Emitter Protocol +`EmitterProtocol` replaces the earlier GeneratorProtocol idea. It defines the interface any emitter implements. Methods reference concrete GenAI Types (strong-typed union where practical) instead of loosely typed dicts. + +Minimal protocol surface (sync for simplicity; an async variant could be added later if required): +``` +class EmitterProtocol(Protocol): + # Called when an invocation is started (before user logic runs) + def on_start(self, invocation: GenAIInvocation) -> None: ... + + # Called when invocation finishes (success or failure). Invocation object now has end_time, outputs, errors populated. + def on_end(self, invocation: GenAIInvocation) -> None: ... + + # Optional: handle aggregated evaluation batches + def on_evaluation_results(self, results: EvaluationResults) -> None: ... + + # Capability flags (may be simple attributes): + emits_spans: bool + emits_metrics: bool + emits_events: bool +``` +Specialized subclasses MAY also exist (e.g., `SpanEmitter`, `MetricsEmitter`, `ContentEventsEmitter`, `EvaluationEmitter`) but they all adhere to the protocol so CompositeEmitter can treat them uniformly. + +### 3.2 CompositeEmitter +Central orchestrator owning ordered emitter chains per lifecycle category. Categories (initial pragmatic set): +- `span_emitters` – produce/annotate spans +- `metrics_emitters` – produce metrics derived from invocations / evaluations +- `content_event_emitters` – emit structured log/event records for input/output/system messages +- `evaluation_emitters` – emit evaluation results representation (standard semantic conv or vendor aggregated flavor) + +Responsibilities: +- Maintain insertion-ordered lists per category. +- Provide registration API supporting: append, prepend, replace (single category), conditional replace-by-type. +- Support third-party declarative registration via entry points and env-var overrides. +- Fan out lifecycle calls: on_start -> targeted categories (span emitters, maybe metrics preallocation), on_end -> span, metrics, content events; on_evaluation_results -> evaluation emitters (and optionally metrics emitters for evaluation metrics). +- Evaluate configuration precedence: (a) explicit programmatic registration, (b) env var directives (replace/append), (c) entry point defaults, (d) built-in defaults. + +### 3.3 Registration & Discovery +Entry point group: `opentelemetry_util_genai_emitters`. + +Each emitter package defines a single entry point referencing a function, typically named `load_emitters`, returning `List[EmitterSpec]`. + +`EmitterSpec` (plain dict) minimal fields: +``` +{ + "name": "SemanticConvSpan", # unique logical name + "kind": "span" | "metrics" | "content_events" | "evaluation", + "factory": callable, # returns an EmitterProtocol instance + "mode": "append" | "replace-category" | "replace-same-name", # default append + "position": "first" | "last" | "before:Name" | "after:Name", # optional ordering hint + "invocation_types": ["LLMInvocation", "AgentInvocation"], # optional filter +} +``` +This mirrors the simplicity of evaluator registration (one entry point -> many specs) and avoids rigid class contracts. Future fields can be added without breaking existing packages. + +Resolution steps: +1. Collect all `EmitterSpec`s from builtins + entry points. +2. Apply ordering hints (single pass; unresolved references ignored with warning). +3. Apply `mode` semantics (`replace-category`, `replace-same-name`). +4. Apply environment variable overrides last. +5. Freeze chains (immutable lists) for cheap hot-path iteration. + +Initial scope treats start/end the same; future phase hooks can extend `EmitterSpec` with e.g. `phases` if required. + +### 3.4 Environment Variable Configuration (Emitters) +Target variables (illustrative naming; adjust for consistency with existing evaluator env var style): +``` +OTEL_INSTRUMENTATION_GENAI_EMITTERS_SPAN= + comma-separated list of emitter names with optional position / mode hints +OTEL_INSTRUMENTATION_GENAI_EMITTERS_METRICS= +OTEL_INSTRUMENTATION_GENAI_EMITTERS_CONTENT_EVENTS= +OTEL_INSTRUMENTATION_GENAI_EMITTERS_EVALUATION= +``` +Advanced syntax example (mirrors evaluator metric selection philosophy): +``` +# Replace span emitter chain with SemanticConv + Traceloop extras appended +OTEL_INSTRUMENTATION_GENAI_EMITTERS_SPAN="replace:SemanticConvSpan,TraceloopSpan" + +# Append Splunk evaluation event aggregator, replacing standard evaluation content event emitter +OTEL_INSTRUMENTATION_GENAI_EMITTERS_EVALUATION="replace-category:SplunkEvaluationAggregator" +``` +(We keep parsing rules simple: prefix directives like `replace:` or `replace-category:`.) + +CompositeEmitter performs parsing; Handler stays ignorant of env var parsing logic (single responsibility). + +### 3.5 Lifecycle Insertion Points (Fine-Grained) +Beyond category-level ordering, third parties may request insertion for specific invocation types and phases. Provide API: +``` +register_emitter(emitter, category, *, position="last", invocation_types=None, mode="append") +``` +During emission, CompositeEmitter filters by invocation type if provided. + +### 3.6 Replace vs Append Semantics +- `append` – emitter added after existing ones (default) +- `prepend` – added to front +- `replace-category` – wipes existing category chain, installs listed emitters +- `replace-same-name` – if emitter with same logical name exists, replace in-place; else append +- (future) `replace-first-of-category` – replace only first builtin keeping vendor augmentations (defer until concrete need). + +### 3.7 Error Handling Strategy +Emitters should never raise upstream; CompositeEmitter wraps calls and logs errors (instrumentation must not break app flow). Provide minimal hook to collect error metrics. + +## 4. Telemetry Flavor Examples +### 4.1 Semantic Convention Span Emitter (Built-In) +- Maps GenAI Invocation fields to proposed / existing OpenTelemetry semantic attributes (e.g., model name, token counts, message roles + truncated content, latency). +- Optionally sends message contents as attributes OR defers to content events emitter (config toggle `OTEL_GENAI_SPAN_ATTACH_MESSAGES=true|false`). + +### 4.2 Content Events Emitter (Built-In) +- Emits structured log records (or span events if chosen) for each input / output / system message with ordering index and role. +- Could be replaced by Splunk aggregated event emitter for evaluation results only, while still keeping standard message events. + +### 4.3 Metrics Emitter (Built-In) +- Emits counters (invocation_count), histograms (latency, prompt_tokens, completion_tokens, total_tokens), up-down counters (inflight_invocations), gauge-like observations (cost if available). +- Derives trace correlation via captured span context. + +### 4.4 Evaluation Results Emitter (Built-In) +- If not aggregated: emits one log/event per `EvaluationResult` with metric name & value. +- If aggregated upstream (Manager sets `EvaluationResults` container), emits single aggregated log record referencing list. + +## 5. Third-Party Emitter Examples +### 5.1 TraceloopEmitter (External Package `opentelemetry-util-genai-emitters-traceloop`) +Purpose: Extend semantic conventions with proprietary attributes absent (or contentious) in current spec (e.g. `traceloop.span.kind`, `request_top_p`, `request_temperature`, `agent_chain_depth`). + +Design: +- Provides a `SpanEmitter` variant that wraps / decorates base Semantic Convention span emitter: either + 1. Replace-same-name mode OR + 2. Append after base span emitter and only add extra attributes (preferred to preserve baseline). +- Reuses shared mapping helpers from `opentelemetry.util.genai.emitters.util`. +- Registers via entry point EmitterSpec with `kind="span"`, `mode="append"`, `invocation_types=None`. + +Example `EmitterSpec` inside `load_emitters()`: +``` +def load_emitters(): + return [ + { + "name": "TraceloopSpan", + "kind": "span", + "factory": lambda: TraceloopSpanEmitter(base_helpers=semantic_helpers), + "position": "after:SemanticConvSpan", + "mode": "append" + } + ] +``` + +Usage scenario: User installs package; by default Traceloop attributes now appear. User can disable by overriding env var to exclude name. + +### 5.2 SplunkEmitter (External Package `opentelemetry-util-genai-emitters-splunk`) +Purpose: Provide vendor-specific enriched evaluation aggregation & optional metrics enrichment. + +Components: +- `SplunkEvaluationAggregator` (category `evaluation`, mode `replace-category` if user chooses) – emits one event containing list of evaluation results plus summarized message previews. +- `SplunkExtraMetricsEmitter` (category `metrics`, mode `append`) – emits cost, model usage, or agent step custom metrics not yet in semantic conventions. + +Composite configuration examples: +``` +# Replace only evaluation emitter chain with Splunk aggregator +export OTEL_GENAI_EMITTERS_EVALUATION="replace-category:SplunkEvaluationAggregator" + +# Append Splunk metrics emitter while keeping default metrics +export OTEL_GENAI_EMITTERS_METRICS="append:SplunkExtraMetrics" +``` +If both Splunk and base evaluation emitter active (user chooses append), Splunk could mark events with vendor attribute `vendor="splunk"` to allow consumer filtering. + +## 6. Configuration & Environment Variables (Proposed Set) +Evaluator env vars already exist pattern-wise; emitters follow similar naming. + +Core toggles: +``` +OTEL_INSTRUMENTATION_GENAI_ENABLE=true|false (master switch) +OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGES=span|events|both|none (controls mapping strategy; defaults to events) + +# Emitter chain directives +OTEL_INSTRUMENTATION_GENAI_EMITTERS_SPAN=... +OTEL_INSTRUMENTATION_GENAI_EMITTERS_METRICS=... +OTEL_INSTRUMENTATION_GENAI_EMITTERS_CONTENT_EVENTS=... +OTEL_INSTRUMENTATION_GENAI_EMITTERS_EVALUATION=... + +# Evaluation manager aggregation toggle (consumed by evaluators, influences evaluation_results emission path) +OTEL_INSTRUMENTATION_GENAI_EVALS_RESULTS_AGGREGATION=true|false +``` +Parsing keeps grammar intentionally narrow: comma-separated tokens; optional directive prefix preceding first token. + +## 7. Extensibility Mechanics +### 7.1 Entry Point Discovery Flow +1. CompositeEmitter initialization. +2. Load builtin emitters (semantic conv baseline) into chains. +3. Discover third-party entry points -> collect specs. +4. Apply ordering + mode semantics. +5. Apply env var chain overrides (final authority). +6. Lock in final emitter lists (immutable for runtime simplicity) unless explicit dynamic modification API used. + +### 7.2 Programmatic API Examples +``` +from opentelemetry.util.genai import Handler, CompositeEmitter, SemanticConvEmitters + +composite = CompositeEmitter.default() +# Programmatically add a custom metrics emitter for only AgentInvocation +composite.register_emitter( + MyAgentMetricsEmitter(), + category="metrics", + position="last", + invocation_types={"AgentInvocation"}, + mode="append" +) +handler = Handler(emitter=composite) +``` + +### 7.3 Invocation-Type Filtering +Emitters that declare `invocation_types` only receive lifecycle calls for those types. Evaluation emitters see `EvaluationResults` independently of invocation type filters. + +## 8. Evaluators Integration +Evaluators (external packages) register via `opentelemetry_util_genai_evaluators` entry point group. The Evaluator Manager: +- Implements `CompletionCallback` and is registered with Handler. +- Samples finished invocations (Sampler protocol) and enqueues for asynchronous evaluation. +- Periodically drains queue, runs each evaluator’s `evaluate()` returning `List[EvaluationResult]`. +- Aggregates results to `EvaluationResults` if `OTEL_INSTRUMENTATION_GENAI_EVALS_RESULTS_AGGREGATION=true` else emits individually. +- Calls `handler.evaluation_results(...)` which triggers CompositeEmitter -> evaluation emitters. + +Evaluators code strictly against GenAI Types (not specific telemetry), ensuring portability across flavors. + +## 9. Lifecycle Overview +Sequence (simplified): +``` +Instrumentation -> handler.start(invocation) + -> composite.on_start(invocation) +User code executes / model call +Instrumentation -> handler.end(invocation) + -> composite.on_end(invocation) + -> completion callbacks (evaluator manager) invoked +Evaluator Manager (async) -> evaluate -> handler.evaluation_results(batch) + -> composite.on_evaluation_results(batch) +SDK exporters forward produced spans/metrics/logs to backends +``` + +## 10. Replacement vs Augmentation Scenarios +| Scenario | User Intent | Configuration | Outcome | +|----------|-------------|---------------|---------| +| Add Traceloop extras | Keep baseline spans + add attrs | install pkg (auto append) | Two span emitters run sequentially; second adds attributes | +| Replace evaluation emission with Splunk aggregator | Want single aggregated event | `OTEL_INSTRUMENTATION_GENAI_EMITTERS_EVALUATION=replace-category:SplunkEvaluationAggregator` | Only Splunk emitter processes evaluation results | +| Add custom cost metrics only for LLMInvocation | Append targeted metrics | programmatic registration with invocation_types | Metrics chain emits cost metrics only on LLM invocations | +| Append metrics only for AgentInvocation while extending evaluation events | Enhance agent metrics, keep base evaluation events | programmatic registration with invocation_types={"AgentInvocation"} | Additional metrics produced only for agent invocations; evaluation events unaffected | +| Replace standard EvaluationResults emitter but keep message content events | Vendor aggregated evaluation events only | env var replace-category for evaluation chain | Evaluation results aggregated into single vendor event; message events still produced individually | +| Keep baseline spans but completely replace content events | Use proprietary message event schema | `OTEL_INSTRUMENTATION_GENAI_EMITTERS_CONTENT_EVENTS=replace-category:VendorMsgEvents` | Only vendor message events emitted; spans & other categories unaffected | + +## 11. Error & Performance Considerations +- Emitters must be lightweight; heavy processing (like large content redaction or summarization) should happen asynchronously or in evaluator layer. +- Guard rails: size limits for message content attributes, truncation helpers in shared utils. +- CompositeEmitter wraps each emitter call in try/except; errors increment internal counter metric `genai.emitter.errors` with labels (emitter_name, category, phase). +- Handler optionally exposes a debug flag to log emitter ordering & configuration resolution. +- Invocation-type filtering executed before expensive work (e.g., deep serialization) to minimize overhead. + +## 12. Minimal Shared Utilities +`opentelemetry.util.genai.emitters.util` provides: +- Attribute mapping helpers (e.g., map_invocation_to_span_attrs(invocation)) +- Token & cost normalization helpers +- Truncation & hashing functions for large inputs +- Safe serialization (to JSON) for events + +## 13. Future Considerations (Not in initial scope) +- Async emitter interface for IO-bound enrichments. +- Dynamic runtime reconfiguration (hot swap emitters) – currently static after init. +- Fine-grained privacy redaction policies / PII classifiers (pluggable later). +- Backpressure / queue for high-volume content events (initial impl synchronous with small volume assumption). +- Unified schema version negotiation among emitters (version attribute for future migrations). + +## 14. Non-Goals +- Replacing OpenTelemetry SDK exporters. +- Providing vendor-specific network export logic (handled at telemetry pipeline level already). +- Building a full evaluation orchestration framework beyond sampler + worker loop (focus remains narrow). + +## 15. Example End-to-End Setup +``` +# 1. User installs base + traceloop + splunk packages +pip install opentelemetry-util-genai opentelemetry-util-genai-emitters-traceloop opentelemetry-util-genai-emitters-splunk + +# 2.

Validation Strategy for Refactor +- Unit tests: ordering resolution, env var parsing, replacement semantics, invocation-type filtering, evaluator integration. +- Property tests (optional): ensure no emitter raises propagates. +- Integration smoke: Traceloop + Splunk side-by-side. + +## 17. Migration Notes from *-dev PoC +- Rename GeneratorProtocol -> EmitterProtocol. +- Move TraceloopCompatEmitter out of built-ins into dedicated `-emitters-traceloop` package; rename to `TraceloopSpanEmitter` (or simply `TraceloopEmitter` if only spans now, can later expand with metrics). +- Continue using the `OTEL_INSTRUMENTATION_GENAI_*` namespace uniformly for both emitters and evaluator-related configuration. +- Shift env var parsing from handler to CompositeEmitter. + +--- +This document should guide the implementation tasks in the refactor branch.

Target State (Abbreviated) +Per architecture spec: +- `EmitterProtocol` (rename of `GeneratorProtocol`) with `on_start/on_end/on_evaluation_results` (evaluation results optional). +- `CompositeEmitter` orchestrating category-specific chains: span, metrics, content_events, evaluation. +- Env variable prefix remains `OTEL_INSTRUMENTATION_GENAI_*` for emitter and evaluator configuration. +- Emitter registration via entry point group `opentelemetry_util_genai_emitters` returning list of `EmitterSpec` dicts (mirrors evaluator registration style). +- Traceloop-specific emitters extracted to separate package `opentelemetry-util-genai-emitters-traceloop` (no compat placeholder inside core). +- Splunk emitters as a separate package demonstrating replace-category for evaluation and append for metrics. +- Handler slimmed: delegates emitter chain construction and env parsing for emitters to `CompositeEmitter` builder. +- Invocation type filtering (optional field in spec) before dispatch. +- Error isolation per-emitter. + +--- +## 4.

Phased Refactoring Plan +Phases designed to keep repository in a buildable state while minimizing churn. Backward compatibility is not required (dev branch) so we can cut over aggressively after internal consistency is ensured. + +### Phase 0: Preparation (Optional Fast Cut) +- Freeze current dev emitters behavior snapshot (tag or doc note) if needed. + +### Phase 1: Core Type & Protocol Renaming +Tasks: +1. Introduce `EmitterProtocol` (new file or modify `interfaces.py`). +2. Copy / adapt existing emitters: rename `start`->`on_start`, `finish`->`on_end`, `error` -> remain separate or optional mapping (decide: we keep `error` or merge into `on_end` with error state attribute). For simplicity retain `error` hook temporarily and have CompositeEmitter call it; architecture doc only mandated on_start/on_end but we can extend. +3. Provide a shim class mapping `GeneratorProtocol` to new interface for incremental migration (optional – since no backward compat needed, can just rename). +4. Update imports across code & tests. + +Exit Criteria: +- Tests compile after rename (even if many tests marked xfail or pending updates). + +### Phase 2: Introduce `CompositeEmitter` +Tasks: +1. Implement new structure with category arrays. +2. Provide adapter function to take legacy emitters and bucket them (SpanEmitter -> span, MetricsEmitter -> metrics, ContentEventsEmitter -> content_events, Evaluation* -> evaluation). +3. Replace `CompositeGenerator` usage in handler with `CompositeEmitter` construction. +4. Remove `CompositeEvaluationEmitter` by merging evaluation emitters into evaluation category. + +Exit Criteria: +- Handler uses new composite; old composite removed or deprecated comment. + +### Phase 3: Configuration & Env Variable Migration +Tasks: +1. Extend parser to support category-specific env vars (optional granular control) under `OTEL_INSTRUMENTATION_GENAI_EMITTERS_*` (SPAN, METRICS, CONTENT_EVENTS, EVALUATION) while still honoring legacy aggregate `OTEL_INSTRUMENTATION_GENAI_EMITTERS`. +2. Move parsing logic from `handler.py` into a `emitter_config.py` or inside CompositeEmitter builder. +3. Keep existing prefix only (no rename); deprecate `generator_kind` semantics. +4. Update tests to cover category-specific overrides + aggregate fallback. +5. Remove now-obsolete `generator_kind` branching. + +Exit Criteria: +- Emission choices driven solely by new env variables. + +### Phase 4: Registration Infrastructure +Tasks: +1. Add entry point group to project `pyproject.toml`: `opentelemetry_util_genai_emitters`. +2. Define `load_emitters_entrypoints()` that collects each entry point's list of `EmitterSpec`. +3. Implement ordering, mode application, and invocation type filtering. +4. Add tests for: append, replace-category, replace-same-name ordering collisions. + +Exit Criteria: +- External example package (temporary stub) can register an extra metrics emitter via entry point and appears in chain. + +### Phase 5: Traceloop Extraction *(completed)* +Delivered: +1. Created `opentelemetry-util-genai-emitters-traceloop` exposing the compat span emitter via entry points. +2. Migrated the legacy emitter out of core and removed handler/config special-casing. +3. Added focused tests ensuring the plug-in captures content and propagates errors correctly. +4. Documentation now instructs installing the plug-in for Traceloop scenarios. + +### Phase 6: Splunk Package Alignment +Tasks: +1. Ensure Splunk package implements two emitters: `SplunkEvaluationAggregator` (evaluation kind, mode replace-category) and `SplunkExtraMetricsEmitter` (metrics kind append). +2. Add entry point registration returning both specs. +3. Implement evaluation aggregation logic (batch -> single event with message preview) per architecture. +4. Write tests verifying replacement of evaluation emitter chain & coexistence of metrics emitters. + +Exit Criteria: +- Splunk tests pass; evaluation events shape validated. + +### Phase 7: Cleanup & Test Rewrite +Tasks: +1. Remove obsolete tests referencing generator kinds & compat paths. +2. Add fresh tests: ordering, env var parsing, invocation type filtering, error isolation, evaluation emission integration. +3. Add minimal performance smoke (ensuring constant-time emitter dispatch overhead measured within threshold; optional). + +Exit Criteria: +- Test suite green. + +### Phase 8: Documentation & Finalization +Tasks: +1. Update README.rst (dev packages) with new env vars & registration model. +2. Ensure `READEM.architecture.md` still matches implementation; adjust if deviations required. +3. Expand this document CHANGELOG with final milestone summary. + +Exit Criteria: +- Docs updated & consistent. + +--- +## 6. Detailed Task List (Backlog Items) +Numbered for incremental execution (referenced in CHANGELOG): +1. Introduce `EmitterProtocol` replacing `GeneratorProtocol` (interfaces rename). +2. Rename emitter classes method names (start->on_start, finish->on_end) & update references. +3. Implement `CompositeEmitter` with categories; port emitters. +4. Merge evaluation emitters into composite evaluation category. +5. Remove `CompositeEvaluationEmitter` and legacy `CompositeGenerator`. +6. Implement new env var parser (`emitter_config.py`). +7. Add support for `OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGES` (span|events|both|none) controlling initialization flags. +8. Remove old `generator_kind` branching in handler. +9. Move emitter configuration building from handler to composite builder. +10. Add entry point group & loader function for emitter specs. +11. Implement ordering + mode resolution logic. +12. Create error wrapping & metrics/logging for per-emitter exceptions. +13. Extract traceloop compat emitter to new package & implement entry point. +14. Remove traceloop special-casing logic from core config. +15. Update tests removing generator/traceloop assumptions. +16. Implement Splunk evaluation aggregator emitter (replace-category behavior). +17. Implement Splunk extra metrics emitter (append behavior). +18. Add tests for Splunk replacement + coexistence scenarios. +19. Implement invocation type filtering using `invocation_types` in spec. +20. Add tests for invocation-type specific emitter (AgentInvocation only metrics example). +21. Documentation: update env var references across repo. +22. Update architecture doc if any pragmatic deviations occurred. +23. Final cleanup: remove deprecated code blocks & transitional shims. + +--- +## 7. Risks & Mitigations +| Risk | Impact | Mitigation | +|------|--------|-----------| +| Large rename causing transient breakage | Test failures during multi-step PR | Perform rename + adapter in single commit; run tests iteratively | +| Entry point ordering cycles | Undefined final ordering | Detect cycle; log warning; fall back to declared order | +| Performance regression in hot path | Increased latency for each invocation | Pre-resolve emitter lists to plain arrays; avoid dynamic attr lookups | +| Missing evaluation results interface parity | Lost evaluator output | Provide temporary compatibility adapter calling new `on_evaluation_results` | +| Splunk aggregator semantics mismatched | Vendor integration confusion | Write contract test with expected event schema shape | + +--- +## 8. Acceptance Criteria Summary +- All old generator naming eliminated from core after Phase 7 (except migration notes). +- New env vars fully control emission; old ones optional or removed by design (PoC freedom). +- Installing traceloop or splunk packages modifies emitter chains without code changes. +- Tests exist for: env var parsing, chain replace/append, invocation filtering, evaluation aggregation, error isolation. +- Architecture document remains accurate. + +--- +## 9.

`util/opentelemetry-util-genai-evals-deepeval/src/opentelemetry/util/evaluator/deepeval.py`, `util/opentelemetry-util-genai-dev/README.refactoring.emitters.demo-scenarios.md`, `.vscode/launch.json`. +- Follow-ups: When publishing the Deepeval adapter, highlight the opt-out behavior in release notes. + +### Task 17: Extract Traceloop compat emitter to plug-in +- Moved the Traceloop compatibility emitter into the new `opentelemetry-util-genai-emitters-traceloop` package and removed all core references. +- Files touched: `util/opentelemetry-util-genai-emitters-traceloop/**`, `util/opentelemetry-util-genai-dev/src/opentelemetry/util/genai/{emitters/configuration.py,emitters/__init__.py,config.py,handler.py,environment_variables.py}`, docs, and launch configs. +- Follow-ups: Monitor adoption of the plug-in and remove any lingering mentions of the legacy compat emitter. + +### Validation Audit (Implementation Status up to Task 12) +Date: 2025-10-05 *(tasks 13–16 added afterwards; run a fresh audit once remaining milestones land)* + +Audit Summary: +- Tasks 1–12 are PRESENT in the codebase and align with the target architecture draft. +- `EmitterProtocol` defined in `interfaces.py`; legacy generator naming removed from active code paths. +- `CompositeEmitter` with category ordering implemented in `emitters/composite.py`. +- Evaluation emitters (`EvaluationMetrics`, `EvaluationEvents`, optional `EvaluationSpans`) integrated as a category inside the composite. +- Env parsing & capture logic delegated to `build_emitter_pipeline` + `Settings`; handler no longer constructs emitters directly (it only invokes the builder). +- Spec-based registration (`EmitterSpec`, `load_emitter_specs`) and category override logic implemented; ordering / replace modes (`replace-category`, `prepend`, `replace-same-name`, `append`) supported. +- Traceloop compat emitter now lives in `opentelemetry-util-genai-emitters-traceloop` and is consumed via entry points. +- Invocation-type filtering NOT YET implemented (pending Task 19 – no `invocation_types` evaluation in dispatch path yet). +- Error isolation: dispatch wrapper catches and logs exceptions (metrics counters still TODO – Task 12 follow-up). + +Outstanding (Not Started Unless Noted): +- Task 13–14: Completed (Traceloop extraction & removal of compat from core). +- Task 15: Test suite rewrite / pruning of legacy generator assumptions (partial – some tests still reference old names; needs cleanup pass). +- Task 16–18: Splunk evaluation aggregator & extra metrics emitter (not implemented here – separate package work pending; current Splunk package adaptation status unverified in this audit). +- Task 19–20: Invocation type filtering & tests (not implemented). +- Task 21–22: Documentation sync & architecture drift review (partially pending; README still legacy prior to this audit, will be rewritten). +- Task 23: Final cleanup / shim removal (future). + +Next Immediate Actions: +1. Implement invocation-type filtering in composite dispatch or during spec instantiation (Task 19). +2. Add metrics counters for emitter failures (extend Task 12 follow-up). +3. Rewrite README (Task 21) – concise quick start + link to architecture. + +Notes: +- Keep CHANGELOG append-only; do not retroactively edit earlier task sections. +- When Task 13 lands, add a new CHANGELOG entry rather than altering this audit. diff --git a/util/opentelemetry-util-genai-dev/README.rst b/util/opentelemetry-util-genai-dev/README.rst index 6688c743df..f9f92f3260 100644 --- a/util/opentelemetry-util-genai-dev/README.rst +++ b/util/opentelemetry-util-genai-dev/README.rst @@ -1,193 +1,21 @@ -OpenTelemetry GenAI Utilities (opentelemetry-util-genai) -======================================================== +OpenTelemetry GenAI Utilities (Concise Guide) +============================================= -A lightweight, extensible toolkit for **observing Generative AI workloads** with OpenTelemetry. -It standardizes the lifecycle of LLM, embedding, and tool invocations; captures structured -content (when allowed); and supports pluggable, asynchronous **evaluation frameworks**. - -.. contents:: Table of Contents - :depth: 3 - :local: - :backlinks: entry - -Vision ------- -Provide **zero/low–friction** primitives so instrumentation authors, platform teams, and -application developers can: - -* Emit semantically consistent telemetry (spans, metrics, events/logs) for GenAI operations. -* Select the *shape* of telemetry via a single environment variable ("flavor"). -* Defer expensive *evaluation* logic off the hot path (asynchronous sampling + background worker). -* Interoperate with existing ecosystems (e.g. Traceloop compatibility) without vendor lock‑in. -* Extend safely: add emitters, evaluators, upload hooks with minimal code. - -High‑Level Architecture ------------------------ -Instrumentation (your code or an auto‑instrumentor) builds domain objects and delegates -lifecycle to a ``TelemetryHandler``.

========================================================================================== +This package plugs the `deepeval `_ metrics +suite into the OpenTelemetry GenAI evaluation pipeline. When it is installed a +``Deepeval`` evaluator is registered automatically and, unless explicitly disabled, +is executed for every LLM/agent invocation alongside the builtin metrics. + +Requirements +------------ + +* ``deepeval`` and its transitive dependencies (installed automatically). +* An LLM provider supported by Deepeval. By default the evaluator uses OpenAI's + ``gpt-4o-mini`` model because it offers the best balance of latency and cost + for judge workloads right now, so make sure ``OPENAI_API_KEY`` is available. + To override the model, set ``DEEPEVAL_EVALUATION_MODEL`` (or ``DEEPEVAL_MODEL`` / + ``OPENAI_MODEL``) to a different deployment along with the corresponding + provider credentials. +* (Optional) ``DEEPEVAL_API_KEY`` if your Deepeval account requires it. + +Configuration +------------- + +Use ``OTEL_INSTRUMENTATION_GENAI_EVALS_EVALUATORS`` to select the metrics that +should run. Leaving the variable unset enables every registered evaluator with its +default metric set. Examples: + +* ``OTEL_INSTRUMENTATION_GENAI_EVALS_EVALUATORS=Deepeval`` – run the default + Deepeval bundle (Bias, Toxicity, Answer Relevancy, Faithfulness). +* ``OTEL_INSTRUMENTATION_GENAI_EVALS_EVALUATORS=Deepeval(LLMInvocation(bias(threshold=0.75)))`` – + override the Bias threshold for LLM invocations and skip the remaining metrics. +* ``OTEL_INSTRUMENTATION_GENAI_EVALS_EVALUATORS=none`` – disable the evaluator entirely. + +Results are emitted through the standard GenAI evaluation emitters (events, +metrics, spans). Each metric includes helper attributes such as +``deepeval.success``, ``deepeval.threshold`` and any evaluation model metadata +returned by Deepeval. Metrics that cannot run because required inputs are missing +(for example Faithfulness without a ``retrieval_context``) are marked as +``label="skipped"`` and carry a ``deepeval.error`` attribute so you can wire the +necessary data or disable that metric explicitly. diff --git a/util/opentelemetry-util-genai-evals-deepeval/pyproject.toml b/util/opentelemetry-util-genai-evals-deepeval/pyproject.toml index 4e51b75e8c..825b76c5be 100644 --- a/util/opentelemetry-util-genai-evals-deepeval/pyproject.toml +++ b/util/opentelemetry-util-genai-evals-deepeval/pyproject.toml @@ -30,8 +30,8 @@ dependencies = [ "opentelemetry-api>=1.31.0", ] -[project.entry-points.opentelemetry_utils_evaluator] -evaluator = "opentelemetry.util.evaluator.deepeval:DeepevalEvaluator" +[project.entry-points.opentelemetry_util_genai_evaluators] +deepeval = "opentelemetry.util.evaluator.deepeval:_REGISTRATION" [project.optional-dependencies] test = ["pytest>=7.0.0"] diff --git a/util/opentelemetry-util-genai-evals-deepeval/pytest.ini b/util/opentelemetry-util-genai-evals-deepeval/pytest.ini index a042e1fe0a..8300e5055e 100644 --- a/util/opentelemetry-util-genai-evals-deepeval/pytest.ini +++ b/util/opentelemetry-util-genai-evals-deepeval/pytest.ini @@ -1,5 +1,4 @@ [pytest] -addopts = -q +addopts = -p no:flaky -q log_cli = false testpaths = tests - diff --git a/util/opentelemetry-util-genai-evals-deepeval/src/opentelemetry/util/evaluator/__init__.py b/util/opentelemetry-util-genai-evals-deepeval/src/opentelemetry/util/evaluator/__init__.py index eb95097fa7..6899628f8b 100644 --- a/util/opentelemetry-util-genai-evals-deepeval/src/opentelemetry/util/evaluator/__init__.py +++ b/util/opentelemetry-util-genai-evals-deepeval/src/opentelemetry/util/evaluator/__init__.py @@ -12,21 +12,8 @@ # See the License for the specific language governing permissions and # limitations under the License. -"""Evaluator scaffolding (Phase 1). +"""Deepeval evaluator plugin package.""" -Provides a minimal pluggable registry for GenAI evaluators.

Refactoring Objectives + +A. Data Model +- Ensure every semconv attribute we emit is backed by a dedicated dataclass field with `metadata={'semconv': ...}` (already largely true). +- Remove / deprecate `chat_generations`: not required—`output_messages` suffices. +- Optionally add explicit optional fields ONLY if Traceloop requires something not derivable from existing semconv fields. (Current assessment: no new core fields needed; traceloop can compute from existing ones.) +- Mark `framework` either: (1) map to a future semconv if defined OR (2) keep as non-semconv; ensure span emitter does not treat it like a semconv attribute (only set if still desired). + +B. Span Emitter (`span.py`) +- Restrict attribute emission to: + * dataclass semconv attributes via `semantic_convention_attributes()`. + * explicit provider/framework bridging if approved (provider already semconv; framework maybe removed or feature-flagged). + * function definitions using semantic conv helper. +- Remove emission of arbitrary `attributes` unless those keys start with `gen_ai.` AND correspond to recognized spec fields (to avoid leaking `ls_*`). +- Add content message emission: when `CAPTURE_MESSAGE_CONTENT=true` AND mode is SPAN or SPAN_AND_EVENT, set `gen_ai.input.messages` and `gen_ai.output.messages`. (Currently done; just guard mode logic once integrated with env evaluation.) + +C. Traceloop Emitter (`traceloop.py`) +- Stop copying non-semconv arbitrary attributes into `traceloop.*` unless they are explicitly part of traceloop flavor contract. +- Derive enumerated prompt/completion attributes from `input_messages` / `output_messages`. +- Include request parameter semconv equivalents but NOT duplicate with `ls_` naming inside semantic conv span flavor. +- Provide mapping table (internal) so additions remain consistent. + +D. LangChain Callback Handler +- Populate only semconv-aligned fields on `LLMInvocation` for core params. +- Move ls_* vendor/legacy fields strictly into `attributes` (NOT new dataclass fields) – for consumption exclusively by traceloop emitter if needed. +- Remove population of `chat_generations`. +- Ensure request_* fields are set directly (temperature, top_p, etc.) and not left duplicated in `attributes` as raw invocation values. + +--- +## 4.

Open Questions / Assumptions +- Assumption: Backward compatibility does not require preserving `chat_generations`; callers rely on `output_messages`. +- Assumption: It is acceptable to drop `ls_*` attributes from semconv spans (they remain accessible via traceloop flavor if that emitter is enabled). +- Assumption: `gen_ai.framework` is temporarily retained; may become an official semconv or be removed later. +- Question: Should `user` (custom JSON) be standardized?

Aligned) -> Document purpose: Prescriptive reference architecture for the refactor of the development PoC ( *-dev* packages ) into `opentelemetry-util-genai` and related emitter / evaluator extension packages. Describes the *target* design (not current PoC state). Backward compatibility is **not** a constraint for this refactor branch. +Status: Updated to reflect the current implementation in the *-dev package as of 2025‑10‑08. + +This document supersedes earlier purely *target* design notes; it now describes the **actual implementation** and marks deferred items.

Emitters sit *above* the SDK using public Span / Metrics / Logs / Events APIs. ## 2. Core Concepts ### 2.1 GenAI Types (Data Model) -Neutral, in-memory domain objects capturing invocation lifecycle independent of final telemetry encoding. Envisioned (extensible) set: +Implemented dataclasses (in `types.py`): - `LLMInvocation` -- `AgentInvocation` -- `RetrievalInvocation` - `EmbeddingInvocation` -- `WorkflowInvocation` -- `StepInvocation` -- `PlannerInvocation` -- `EvaluationResults` (represents a batch/list of individual `EvaluationResult` objects aggregated by evaluator logic or raw single result when not aggregated) +- `Workflow` +- `AgentInvocation` +- `Task` +- `ToolCall` +- `EvaluationResult` (atomic) -Common base shape (conceptual): -``` -GenAIInvocation: - id: str (stable unique id – UUID or deterministic) - parent_id: Optional[str] - span_context: CapturedSpanContext (snapshot at creation) - start_time_ns: int - end_time_ns: Optional[int] - model/provider/tool identifiers (type-specific fields) - input_messages: List[Message] - output_messages: List[Message] - system_messages: List[Message] - tokens_prompt / tokens_completion / cost metrics (optional collected or provided later) - attributes: MutableMapping[str, Any] (extensible metadata) -``` -Messages hold role, content (structured parts), and optional metadata. +Planned (not yet implemented): `RetrievalInvocation`, `PlannerInvocation`, aggregated `EvaluationResults` wrapper (currently lists of `EvaluationResult` are passed directly). -#### 2.1.1 LLMInvocation semantic attribute contract +Base dataclass: `GenAI` – fields include timing (`start_time`, `end_time`), identity (`run_id`, `parent_run_id`), context (`provider`, `framework`, `agent_*`, `system`, `conversation_id`, `data_source_id`), plus `attributes: dict[str, Any]` for free-form metadata. -`LLMInvocation` now exposes the semantic-convention friendly fields directly on the dataclass instead of hiding everything in the generic `attributes` dictionary. Each field carries metadata (`metadata={"semconv": }`) so emitters can enumerate the canonical keys without hard-coding property names. Highlights: +Semantic attributes: fields tagged with `metadata={"semconv": }` feed `semantic_convention_attributes()` which returns only populated values; emitters rely on this reflective approach (no hard‑coded attribute lists). -- Base `GenAI` class adds `system`, `conversation_id`, `data_source_id`, `agent_name`, and `agent_id` to mirror proposed semantics. -- Request knobs (`request_temperature`, `request_top_p`, `request_top_k`, `request_frequency_penalty`, `request_presence_penalty`, `request_stop_sequences`, `request_max_tokens`, `request_choice_count`, `request_seed`, `request_encoding_formats`) and response details (`response_model_name`, `response_id`, `response_finish_reasons`, `response_service_tier`, `response_system_fingerprint`) are first-class fields. -- Token usage (`input_tokens`, `output_tokens`) and output modality (`output_type`) likewise map 1:1 to semantic attributes. -- The helper `semantic_convention_attributes()` walks the dataclass field metadata to produce a dict of populated semantic attributes; built-in emitters use this instead of bespoke mapping tables. +Messages: `InputMessage` / `OutputMessage` each hold `role` and `parts` (which may be `Text`, `ToolCall`, `ToolCallResponse`, or arbitrary parts). Output messages include `finish_reason`. -The `attributes: Dict[str, Any]` bag is still present for vendor or instrumentation-specific metadata. Built-in emitters only read keys that already have a semantic prefix (`gen_ai.*`, `traceloop.*`, etc.); everything else stays in-process unless a plug-in cares about it. This keeps semantic output deterministic while allowing instrumentation to stash raw extras that other emitters (Traceloop, Splunk, custom) can enrich. +`EvaluationResult` fields: `metric_name`, optional `score` (float), `label` (categorical outcome), `explanation`, `error` (contains `type`, `message`), `attributes` (additional evaluator-specific key/values). No aggregate wrapper class yet. -`EvaluationResult` (atomic) includes: metric_name, value (numeric or categorical), pass_fail (optional bool), confidence(optional), reasoning(optional), latency(optional), additional_attrs. +### 2.2 TelemetryHandler +`TelemetryHandler` (formerly referred to as `Handler`) orchestrates lifecycle & evaluation emission. -### 2.2 Handler -`Handler` is the façade used by instrumentation and evaluators. Responsibilities: -- Construct GenAI Types (factory helpers) capturing span context immediately (even if spans later suppressed or not emitted). -- Provide lifecycle methods: `start_*(invocation)` and `end_*(invocation)` OR a high-level context manager convenience. -- Delegate to a `CompositeEmitter` for actual telemetry emission at well-defined lifecycle points. -- Offer `evaluation_results(results: EvaluationResults)` for evaluators. -- Maintain optional registry of completion callbacks (e.g., Evaluation Manager) implementing `CompletionCallback.on_completion(gen_ai_invocation)`. +Capabilities: +- Type-specific lifecycle: `start_llm`, `stop_llm`, `fail_llm`, plus `start/stop/fail` for embedding, tool call, workflow, agent, task. +- Generic dispatchers: `start(obj)`, `finish(obj)`, `fail(obj, error)`. +- Dynamic content capture refresh (`_refresh_capture_content`) each LLM / agentic start (re-reads env + experimental gating). +- Delegation to `CompositeEmitter` (`on_start`, `on_end`, `on_error`, `on_evaluation_results`). +- Completion callback registry (`CompletionCallback`); Evaluation Manager auto-registers if evaluators present. +- Evaluation emission via `evaluation_results(invocation, list[EvaluationResult])`. -### 2.3 Span Context Capture -When a GenAI Type is instantiated, the active span (if any) is queried and encoded into a lightweight `CapturedSpanContext` containing trace_id, span_id, trace_flags, trace_state. This allows metrics/events emitters to correlate even if span emission is disabled. +### 2.3 Span / Trace Correlation +Invocation objects hold a `span` reference (if spans enabled). There is no separate captured-span-context snapshot object; emitters access the span directly. If spans are disabled, evaluation sampling falls back to queueing (trace-id sampling devolves to unconditional enqueue with a debug log). ## 3. Emitter Architecture -### 3.1 Emitter Protocol -`EmitterProtocol` replaces the earlier GeneratorProtocol idea. It defines the interface any emitter implements. Methods reference concrete GenAI Types (strong-typed union where practical) instead of loosely typed dicts. - -Minimal protocol surface (sync for simplicity; an async variant could be added later if required): -``` -class EmitterProtocol(Protocol): - # Called when an invocation is started (before user logic runs) - def on_start(self, invocation: GenAIInvocation) -> None: ... - - # Called when invocation finishes (success or failure). Invocation object now has end_time, outputs, errors populated. - def on_end(self, invocation: GenAIInvocation) -> None: ... +### 3.1 Protocol & Meta +`EmitterProtocol` offers: `on_start(obj)`, `on_end(obj)`, `on_error(error, obj)`, `on_evaluation_results(results, obj=None)`. Capability flags described in early design are **not implemented** (deferred). Invocation-type filtering is injected by wrapping `handles` when an `EmitterSpec` sets `invocation_types`. - # Optional: handle aggregated evaluation batches - def on_evaluation_results(self, results: EvaluationResults) -> None: ... - - # Capability flags (may be simple attributes): - emits_spans: bool - emits_metrics: bool - emits_events: bool -``` -Specialized subclasses MAY also exist (e.g., `SpanEmitter`, `MetricsEmitter`, `ContentEventsEmitter`, `EvaluationEmitter`) but they all adhere to the protocol so CompositeEmitter can treat them uniformly. +`EmitterMeta` supplies `role`, `name`, optional `override`, and a default `handles(obj)` returning `True`. Role names are informational and may not match category names (e.g., `MetricsEmitter.role == "metric"`). ### 3.2 CompositeEmitter -Central orchestrator owning ordered emitter chains per lifecycle category. Categories (initial pragmatic set): -- `span_emitters` – produce/annotate spans -- `metrics_emitters` – produce metrics derived from invocations / evaluations -- `content_event_emitters` – emit structured log/event records for input/output/system messages -- `evaluation_emitters` – emit evaluation results representation (standard semantic conv or vendor aggregated flavor) +Defines ordered category dispatch with explicit sequences: +- Start order: `span`, `metrics`, `content_events` +- End/error order: `evaluation`, `metrics`, `content_events`, `span` (span ends last so other emitters can enrich attributes first; evaluation emitters appear first in end sequence to allow flush behavior). -Responsibilities: -- Maintain insertion-ordered lists per category. -- Provide registration API supporting: append, prepend, replace (single category), conditional replace-by-type. -- Support third-party declarative registration via entry points and env-var overrides. -- Fan out lifecycle calls: on_start -> targeted categories (span emitters, maybe metrics preallocation), on_end -> span, metrics, content events; on_evaluation_results -> evaluation emitters (and optionally metrics emitters for evaluation metrics). -- Evaluate configuration precedence: (a) explicit programmatic registration, (b) env var directives (replace/append), (c) entry point defaults, (d) built-in defaults. +Public API (current): `iter_emitters(categories)`, `emitters_for(category)`, `add_emitter(category, emitter)`. A richer `register_emitter(..., position, mode)` API is **not yet implemented**. -### 3.3 Registration & Discovery -Entry point group: `opentelemetry_util_genai_emitters`. +### 3.3 EmitterSpec & Discovery +Entry point group: `opentelemetry_util_genai_emitters` (vendor packages contribute specs). -Each emitter package defines a single entry point referencing a function, typically named `load_emitters`, returning `List[EmitterSpec]`. +`EmitterSpec` fields: +- `name` +- `category` (`span`, `metrics`, `content_events`, `evaluation`) +- `factory(context)` +- `mode` (`append`, `prepend`, `replace-category`, `replace-same-name`) +- `after`, `before` (ordering hints – **currently unused / inert**) +- `invocation_types` (allow-list; implemented via dynamic `handles` wrapping) -`EmitterSpec` (plain dict) minimal fields: -``` -{ - "name": "SemanticConvSpan", # unique logical name - "kind": "span" | "metrics" | "content_events" | "evaluation", - "factory": callable, # returns an EmitterProtocol instance - "mode": "append" | "replace-category" | "replace-same-name", # default append - "position": "first" | "last" | "before:Name" | "after:Name", # optional ordering hint - "invocation_types": ["LLMInvocation", "AgentInvocation"], # optional filter -} -``` -This mirrors the simplicity of evaluator registration (one entry point -> many specs) and avoids rigid class contracts. Future fields can be added without breaking existing packages. +Ordering hints will either gain a resolver or be removed (open item). -Resolution steps: -1. Collect all `EmitterSpec`s from builtins + entry points. -2. Apply ordering hints (single pass; unresolved references ignored with warning). -3. Apply `mode` semantics (`replace-category`, `replace-same-name`). -4. Apply environment variable overrides last. -5. Freeze chains (immutable lists) for cheap hot-path iteration. +### 3.4 Configuration (Emitters) +Baseline selection: `OTEL_INSTRUMENTATION_GENAI_EMITTERS` (comma-separated tokens): +- `span` (default) +- `span_metric` +- `span_metric_event` +- Additional tokens -> extra emitters (e.g. `traceloop_compat`). If the only token is `traceloop_compat`, semconv span is suppressed (`only_traceloop_compat`). -Initial scope treats start/end the same; future phase hooks can extend `EmitterSpec` with e.g. `phases` if required. +Category overrides (`OTEL_INSTRUMENTATION_GENAI_EMITTERS_` with `` = `SPAN|METRICS|CONTENT_EVENTS|EVALUATION`) support directives: `append:`, `prepend:`, `replace:` (alias for `replace-category`), `replace-category:`, `replace-same-name:`. -### 3.4 Environment Variable Configuration (Emitters) -Target variables (illustrative naming; adjust for consistency with existing evaluator env var style): -``` -OTEL_INSTRUMENTATION_GENAI_EMITTERS_SPAN= - comma-separated list of emitter names with optional position / mode hints -OTEL_INSTRUMENTATION_GENAI_EMITTERS_METRICS= -OTEL_INSTRUMENTATION_GENAI_EMITTERS_CONTENT_EVENTS= -OTEL_INSTRUMENTATION_GENAI_EMITTERS_EVALUATION= -``` -Advanced syntax example (mirrors evaluator metric selection philosophy): -``` -# Replace span emitter chain with SemanticConv + Traceloop extras appended -OTEL_INSTRUMENTATION_GENAI_EMITTERS_SPAN="replace:SemanticConvSpan,TraceloopSpan" - -# Append Splunk evaluation event aggregator, replacing standard evaluation content event emitter -OTEL_INSTRUMENTATION_GENAI_EMITTERS_EVALUATION="replace-category:SplunkEvaluationAggregator" -``` -(We keep parsing rules simple: prefix directives like `replace:` or `replace-category:`.) - -CompositeEmitter performs parsing; Handler stays ignorant of env var parsing logic (single responsibility). - -### 3.5 Lifecycle Insertion Points (Fine-Grained) -Beyond category-level ordering, third parties may request insertion for specific invocation types and phases. Provide API: -``` -register_emitter(emitter, category, *, position="last", invocation_types=None, mode="append") -``` -During emission, CompositeEmitter filters by invocation type if provided. +### 3.5 Invocation-Type Filtering +Implemented through `EmitterSpec.invocation_types`; configuration layer replaces/augments each emitter’s `handles` method to short‑circuit dispatch cheaply. No explicit positional insertion API yet; runtime additions can call `add_emitter` (append only). ### 3.6 Replace vs Append Semantics -- `append` – emitter added after existing ones (default) -- `prepend` – added to front -- `replace-category` – wipes existing category chain, installs listed emitters -- `replace-same-name` – if emitter with same logical name exists, replace in-place; else append -- (future) `replace-first-of-category` – replace only first builtin keeping vendor augmentations (defer until concrete need). - -### 3.7 Error Handling Strategy -Emitters should never raise upstream; CompositeEmitter wraps calls and logs errors (instrumentation must not break app flow). Provide minimal hook to collect error metrics. - -## 4. Telemetry Flavor Examples -### 4.1 Semantic Convention Span Emitter (Built-In) -- Maps GenAI Invocation fields to proposed / existing OpenTelemetry semantic attributes (e.g., model name, token counts, message roles + truncated content, latency). -- Optionally sends message contents as attributes OR defers to content events emitter (config toggle `OTEL_GENAI_SPAN_ATTACH_MESSAGES=true|false`). - -### 4.2 Content Events Emitter (Built-In) -- Emits structured log records (or span events if chosen) for each input / output / system message with ordering index and role. -- Could be replaced by Splunk aggregated event emitter for evaluation results only, while still keeping standard message events. - -### 4.3 Metrics Emitter (Built-In) -- Emits counters (invocation_count), histograms (latency, prompt_tokens, completion_tokens, total_tokens), up-down counters (inflight_invocations), gauge-like observations (cost if available). -- Derives trace correlation via captured span context. - -### 4.4 Evaluation Results Emitter (Built-In) -- If not aggregated: emits one log/event per `EvaluationResult` with metric name & value. -- If aggregated upstream (Manager sets `EvaluationResults` container), emits single aggregated log record referencing list. - -## 5. Third-Party Emitter Examples -### 5.1 TraceloopEmitter (External Package `opentelemetry-util-genai-emitters-traceloop`) -Purpose: Extend semantic conventions with proprietary attributes absent (or contentious) in current spec (e.g. `traceloop.span.kind`, `request_top_p`, `request_temperature`, `agent_chain_depth`). - -Design: -- Provides a `SpanEmitter` variant that wraps / decorates base Semantic Convention span emitter: either - 1. Replace-same-name mode OR - 2. Append after base span emitter and only add extra attributes (preferred to preserve baseline). -- Reuses shared mapping helpers from `opentelemetry.util.genai.emitters.util`. -- Registers via entry point EmitterSpec with `kind="span"`, `mode="append"`, `invocation_types=None`. - -Example `EmitterSpec` inside `load_emitters()`: -``` -def load_emitters(): - return [ - { - "name": "TraceloopSpan", - "kind": "span", - "factory": lambda: TraceloopSpanEmitter(base_helpers=semantic_helpers), - "position": "after:SemanticConvSpan", - "mode": "append" - } - ] -``` +Supported modes: `append`, `prepend`, `replace-category` (alias `replace`), `replace-same-name`. Ordering hints (`after` / `before`) are present but inactive. -Usage scenario: User installs package; by default Traceloop attributes now appear. User can disable by overriding env var to exclude name. +### 3.7 Error Handling +CompositeEmitter wraps all emitter calls; failures are debug‑logged. Error metrics hook (`genai.emitter.errors`) is **not yet implemented** (planned enhancement). -### 5.2 SplunkEmitter (External Package `opentelemetry-util-genai-emitters-splunk`) -Purpose: Provide vendor-specific enriched evaluation aggregation & optional metrics enrichment. +## 4. Built-In Telemetry Emitters +### 4.1 SpanEmitter +Emits semantic attributes, optional input/output message content, system instructions, function definitions, token usage, and agent context. Finalization order ensures attributes set before span closure. -Components: -- `SplunkEvaluationAggregator` (category `evaluation`, mode `replace-category` if user chooses) – emits one event containing list of evaluation results plus summarized message previews. -- `SplunkExtraMetricsEmitter` (category `metrics`, mode `append`) – emits cost, model usage, or agent step custom metrics not yet in semantic conventions. +### 4.2 MetricsEmitter +Records durations and token usage to histograms: `gen_ai.client.operation.duration`, `gen_ai.client.token.usage`, plus agentic histograms (`gen_ai.workflow.duration`, `gen_ai.agent.duration`, `gen_ai.task.duration`). Role string is `metric` (singular) – may diverge from category name `metrics`. -Composite configuration examples: -``` -# Replace only evaluation emitter chain with Splunk aggregator -export OTEL_GENAI_EMITTERS_EVALUATION="replace-category:SplunkEvaluationAggregator" +### 4.3 ContentEventsEmitter +Emits **one** structured log record summarizing an entire LLM invocation (inputs, outputs, system instructions) — a deliberate deviation from earlier message-per-event concept to reduce event volume. Agent/workflow/task event emission is commented out (future option). -# Append Splunk metrics emitter while keeping default metrics -export OTEL_GENAI_EMITTERS_METRICS="append:SplunkExtraMetrics" -``` -If both Splunk and base evaluation emitter active (user chooses append), Splunk could mark events with vendor attribute `vendor="splunk"` to allow consumer filtering. - -## 6. Configuration & Environment Variables (Proposed Set) -Evaluator env vars already exist pattern-wise; emitters follow similar naming. +### 4.4 Evaluation Emitters +Always present: +- `EvaluationMetricsEmitter` – histogram `gen_ai.evaluation.score` per numeric score. +- `EvaluationEventsEmitter` – event per `EvaluationResult`; optional legacy variant via `OTEL_GENAI_EVALUATION_EVENT_LEGACY`. -Core toggles: -``` -OTEL_INSTRUMENTATION_GENAI_ENABLE=true|false (master switch) -OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGES=span|events|both|none (controls mapping strategy; defaults to events) +Aggregation flag affects batching only (emitters remain active either way). -# Emitter chain directives -OTEL_INSTRUMENTATION_GENAI_EMITTERS_SPAN=... -OTEL_INSTRUMENTATION_GENAI_EMITTERS_METRICS=... -OTEL_INSTRUMENTATION_GENAI_EMITTERS_CONTENT_EVENTS=... -OTEL_INSTRUMENTATION_GENAI_EMITTERS_EVALUATION=... +## 5. Third-Party Emitters (External Packages) +- Traceloop span compatibility (`opentelemetry-util-genai-emitters-traceloop`). +- Splunk evaluation aggregation / extra metrics (`opentelemetry-util-genai-emitters-splunk`). -# Evaluation manager aggregation toggle (consumed by evaluators, influences evaluation_results emission path) -OTEL_INSTRUMENTATION_GENAI_EVALS_RESULTS_AGGREGATION=true|false -``` -Parsing keeps grammar intentionally narrow: comma-separated tokens; optional directive prefix preceding first token. +## 6.

Extensibility Mechanics -### 7.1 Entry Point Discovery Flow -1. CompositeEmitter initialization. -2. Load builtin emitters (semantic conv baseline) into chains. -3. Discover third-party entry points -> collect specs. -4. Apply ordering + mode semantics. -5. Apply env var chain overrides (final authority). -6. Lock in final emitter lists (immutable for runtime simplicity) unless explicit dynamic modification API used. - -### 7.2 Programmatic API Examples -``` -from opentelemetry.util.genai import Handler, CompositeEmitter, SemanticConvEmitters - -composite = CompositeEmitter.default() -# Programmatically add a custom metrics emitter for only AgentInvocation -composite.register_emitter( - MyAgentMetricsEmitter(), - category="metrics", - position="last", - invocation_types={"AgentInvocation"}, - mode="append" -) -handler = Handler(emitter=composite) -``` +### 7.1 Entry Point Flow +1. Parse baseline & extras. +2. Register built-ins (span/metrics/content/evaluation). +3. Load entry point emitter specs & register. +4. Apply category overrides. +5. Instantiate `CompositeEmitter` with resolved category lists. + +### 7.2 Programmatic API (Current State) +`CompositeEmitter.add_emitter(category, emitter)` (append). A richer `register_emitter` API (mode + position) is **planned**. -### 7.3 Invocation-Type Filtering -Emitters that declare `invocation_types` only receive lifecycle calls for those types. Evaluation emitters see `EvaluationResults` independently of invocation type filters. +### 7.3 Invocation Type Filtering +`EmitterSpec.invocation_types` drives dynamic `handles` wrapper (fast pre-dispatch predicate). Evaluation emitters see results independently of invocation type filtering. ## 8. Evaluators Integration -Evaluators (external packages) register via `opentelemetry_util_genai_evaluators` entry point group. The Evaluator Manager: -- Implements `CompletionCallback` and is registered with Handler. -- Samples finished invocations (Sampler protocol) and enqueues for asynchronous evaluation. -- Periodically drains queue, runs each evaluator’s `evaluate()` returning `List[EvaluationResult]`. -- Aggregates results to `EvaluationResults` if `OTEL_INSTRUMENTATION_GENAI_EVALS_RESULTS_AGGREGATION=true` else emits individually. -- Calls `handler.evaluation_results(...)` which triggers CompositeEmitter -> evaluation emitters. +Entry point group: `opentelemetry_util_genai_evaluators`. -Evaluators code strictly against GenAI Types (not specific telemetry), ensuring portability across flavors. +Evaluation Manager: +- Auto-registers if evaluators available. +- Trace-id ratio sampling via `OTEL_INSTRUMENTATION_GENAI_EVALUATION_SAMPLE_RATE` (falls back if no span context). +- Parses evaluator grammar into per-type plans (metric + options). +- Aggregation flag merges buckets into a single list when true. +- Emits lists of `EvaluationResult` (no wrapper class yet). +- Marks invocation `attributes["gen_ai.evaluation.executed"] = True` post emission. ## 9.

Error & Performance Considerations -- Emitters must be lightweight; heavy processing (like large content redaction or summarization) should happen asynchronously or in evaluator layer. -- Guard rails: size limits for message content attributes, truncation helpers in shared utils. -- CompositeEmitter wraps each emitter call in try/except; errors increment internal counter metric `genai.emitter.errors` with labels (emitter_name, category, phase). -- Handler optionally exposes a debug flag to log emitter ordering & configuration resolution. -- Invocation-type filtering executed before expensive work (e.g., deep serialization) to minimize overhead. - -## 12. Minimal Shared Utilities -`opentelemetry.util.genai.emitters.util` provides: -- Attribute mapping helpers (e.g., map_invocation_to_span_attrs(invocation)) -- Token & cost normalization helpers -- Truncation & hashing functions for large inputs -- Safe serialization (to JSON) for events - -## 13. Future Considerations (Not in initial scope) -- Async emitter interface for IO-bound enrichments. -- Dynamic runtime reconfiguration (hot swap emitters) – currently static after init. -- Fine-grained privacy redaction policies / PII classifiers (pluggable later). -- Backpressure / queue for high-volume content events (initial impl synchronous with small volume assumption). -- Unified schema version negotiation among emitters (version attribute for future migrations). +- Emitters sandboxed (exceptions suppressed & debug logged). +- No error metric yet (planned: `genai.emitter.errors`). +- Content capture gated by experimental opt-in to prevent accidental large data egress. +- Single content event per invocation reduces volume. +- Invocation-type filtering occurs before heavy serialization. + +## 12. Shared Utilities +`emitters/utils.py` includes: semantic attribute filtering, message serialization, enumeration builders (prompt/completion), function definition mapping, finish-time token usage application. Truncation / hashing helpers & PII redaction are **not yet implemented** (privacy work deferred). + +## 13. Future Considerations +- Implement ordering resolver for `after` / `before` hints. +- Programmatic rich registration API (mode + position) & removal. +- Error metrics instrumentation. +- Aggregated `EvaluationResults` wrapper (with evaluator latency, counts). +- Privacy redaction & size-limiting/truncation helpers. +- Async emitters & dynamic hot-reload (deferred). +- Backpressure strategies for high-volume content events. ## 14. Non-Goals -- Replacing OpenTelemetry SDK exporters. -- Providing vendor-specific network export logic (handled at telemetry pipeline level already). -- Building a full evaluation orchestration framework beyond sampler + worker loop (focus remains narrow). +Unchanged: Not replacing SDK exporters; no vendor-specific network export logic; minimal evaluation orchestration (queue + sampling + worker only). -## 15.

Key divergences concern: + +* Naming / protocol drift (`TelemetryHandler` vs proposed `Handler`; `EmitterMeta.role` values differ from documented category names; `MetricsEmitter.role = "metric"` vs expected `metrics`). +* Category names / ordering semantics differ slightly from the architecture doc (implementation uses `span`, `metrics`, `content_events`, `evaluation` with explicit start/end ordering arrays; architecture text implies fan-out with some different phrasing and capability flags). +* Evaluation results aggregation: implementation aggregates only when env flag set; architecture doc matches this but does not mention dual emitters (metrics + events) always registered. +* Environment variable grammar: supports additional directives (`prepend`, `replace-same-name`) and a consolidated baseline selector `OTEL_INSTRUMENTATION_GENAI_EMITTERS` (values: `span`, `span_metric`, `span_metric_event`, plus extras) not fully described in current architecture README. +* Content capture gating depends on experimental semantic convention opt-in (`OTEL_SEMCONV_STABILITY_OPT_IN=gen_ai_latest_experimental`); doc currently presents capture variables w/o experimental caveat. +* Invocation types extended (Workflow, AgentInvocation, Task, EmbeddingInvocation, ToolCall) with additional metrics; architecture snapshot partially anticipates but does not detail metrics instrumentation for agentic types. +* Missing `EvaluationResults` aggregate class (architecture document references an aggregate container) – implementation forwards raw `list[EvaluationResult]`. +* No explicit `CompositeEmitter.register_emitter` public API (architecture describes one); implementation relies on env parsing + spec registration but lacks runtime chain mutation helpers beyond instantiation. +* Evaluator plugin system more elaborate than described (plan parsing, per-type metric configuration), but lacks an abstraction for aggregated vs non-aggregated result object. +* Some TODO / compatibility code (e.g. legacy event names, traceloop compat paths) not captured in architecture doc. + +--- +## Detailed Findings + +### 1. Types (`types.py`) +| Aspect | Implementation | Architecture Expectation | Finding | +|--------|----------------|--------------------------|---------| +| Base class name | `GenAI` dataclass | `GenAIInvocation` conceptually | Minor naming divergence (fine if documented) | +| Semantic attribute surfacing | Dataclass fields with `metadata{"semconv"}` + `semantic_convention_attributes()` | Matches spec | ✅ | +| Message modeling | `InputMessage` / `OutputMessage` with `parts` (Text / ToolCall / ToolCallResponse / Any) | Doc mentions role/content parts | ✅ | +| Additional invocation types | `EmbeddingInvocation`, `Workflow`, `AgentInvocation`, `Task`, `ToolCall` | Architecture lists prospective types (Agent, Workflow, Step/Task) | ✅ (needs README refresh) | +| Evaluation aggregate | Only `EvaluationResult` (atomic) | `EvaluationResults` aggregate class referenced | Missing class or doc update required | +| Error representation | `Error(message, type)` | Architecture brief mention only | ✅ | +| Token fields for embedding | `input_tokens` only; no output tokens | Acceptable (embedding output token concept ambiguous) | Note for doc | + +### 2. Interfaces / Protocols (`interfaces.py`) +* `EmitterProtocol` includes `on_error` (architecture simplified protocol omitted this) and `on_evaluation_results(results, obj=None)` returns `None` – doc should reflect extra hook. +* `EmitterProtocol` does not define capability flags (`emits_spans`, etc.) – remove or document as deferred. +* `EmitterMeta` carries `role`, `name`, `override` plus `handles(obj)` predicate. Architecture describes categories & invocation type filtering; actual filtering implemented by dynamically wrapping `handles` in configuration layer, not inherent to protocol. + +### 3. Handler (`handler.py`) +* Named `TelemetryHandler` (vs `Handler`). Provides granular per-type start/stop/fail plus generic `start/finish/fail` dispatchers. Architecture README should adopt this or specify alias. +* Content capture refresh: `_refresh_capture_content()` inspects env each LLM start; architecture envisioned central config at initialization – highlight dynamic refresh behavior. +* Completion callbacks implemented; evaluation manager auto-registered only if evaluators present. +* Evaluation emission method signature: `evaluation_results(invocation, results: list[EvaluationResult])` (no EvaluationResults wrapper). + +### 4. Emitters – Spec & Configuration +| Component | Implementation | Difference / Issue | +|-----------|----------------|--------------------| +| Spec class | `EmitterSpec(name, category, factory, mode, after, before, invocation_types)` | Architecture spec fields differ: uses `kind`, `position` with before/after semantics; doc must sync to actual names. | +| Modes supported | `append` (default), `replace-category`, `prepend`, `replace-same-name` | Architecture lists same + some textual differences; confirm naming. | +| Ordering hints | `after`, `before` sequences present on spec but unused in `build_emitter_pipeline` ordering logic (no explicit resolution code) | Potential gap: `after` / `before` not applied; doc or code update needed. | +| Category overrides | Env var parsing yields `CategoryOverride(mode, emitter_names)`; directives: `append`, `prepend`, `replace`, `replace-category`, `replace-same-name` | Architecture examples use `replace-category:` prefix – consistent; need to document accepted aliases (`replace:`). | +| Programmatic registration | No public `register_emitter` on `CompositeEmitter` (only `add_emitter` without ordering/mode handling) | Missing or intentionally deferred; document limitation. | +| Invocation type filtering | Implemented by wrapping `.handles` via dynamic method patch in `_instantiate_category` | Implementation detail differs from design’s declarative `invocation_types` filter; should document. | +| Content capture gating | Controlled by `Settings.capture_messages_mode`, `capture_messages_override`, plus experimental mode check | Architecture lacks experimental stable/unstable semantics – update needed. | + +### 5. Emitters – Individual +* `SpanEmitter`: Implements content capture for input and output messages; enumerates request functions; adds supplemental filtered `attributes` keys restricted to semantic + allowed extras. Adds system instructions as `gen_ai.system.instructions` attribute (not in architecture doc – add). +* `MetricsEmitter`: Role string is `metric` (singular) but category configured as `metrics`; potential mismatch for introspection (only used by composite lists). Should standardize or clarify role vs category concept. +* `ContentEventsEmitter`: Currently emits only a single event summarizing an entire LLM invocation (NOT per message). Architecture doc originally described potentially one event per message; adjust doc or implementation. Commented-out code hints at future agent/workflow events. +* `EvaluationMetricsEmitter` and `EvaluationEventsEmitter` are both always registered; architecture doc envisioned possibly a single evaluation emitter chain – update. +* Missing vendor emitters (Traceloop, Splunk) in this dev package – expected to come from separate packages; document absence and extension points. + +### 6. CompositeEmitter (`composite.py`) +* Enforces start ordering (`span`, `metrics`, `content_events`) and end ordering (`evaluation`, `metrics`, `content_events`, `span`). Architecture described span first on start and last on end – consistent; evaluation ordering should be clarified (evaluation emitters do not receive lifecycle end events except via explicit code path inside dispatch – design doc should reflect evaluation results are dispatched separately, plus evaluation emitters ALSO receive on_end/on_error per dispatch ordering?). +* Evaluation emitters only receive `on_evaluation_results`; they are also iterated in `_CATEGORY_END_ORDER` so they receive `on_end` / `on_error` (currently `_CATEGORY_END_ORDER` begins with `evaluation`). Architecture doc should clarify this hook (flush semantics) or code should drop them if not required. + +### 7. Configuration (`config.py` + env vars) +* Baseline multi-token env var `OTEL_INSTRUMENTATION_GENAI_EMITTERS` drives enabling of span/metrics/content events – not fully documented in architecture README. +* Category-specific overrides parse directives with optional colon prefix (`replace:SemanticConvSpan,TraceloopSpan`). Accepts synonyms (`replace`, `replace-category`). Additional directive `replace-same-name` supported though not documented earlier. +* Legacy capture compatibility via `OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT` still influences handler refresh; architecture doc treats capture controls more simply. +* Evaluation sample rate env var `OTEL_INSTRUMENTATION_GENAI_EVALUATION_SAMPLE_RATE` not described in architecture doc. +* Legacy evaluation event flag `OTEL_GENAI_EVALUATION_EVENT_LEGACY` not mentioned. + +### 8. Evaluation Manager +* Sampling uses Span trace ID with `TraceIdRatioBased`; architecture doc did not mention sampling; add section. +* Complex evaluator config grammar implemented (supports per-metric options) – architecture doc only lightly sketches grammar; ensure updated examples include options syntax (already present in env var docstring). +* Aggregation implemented as boolean flag; architecture doc consistent but lacks detail that evaluation metrics emitter and events run regardless of aggregation (list vs per-bucket emission difference). +* Manager flags invocation with attribute `gen_ai.evaluation.executed` – not documented. + +### 9. Missing / Deferred Features +| Feature | Architecture Status | Implementation Status | Action | +|---------|---------------------|------------------------|--------| +| `EvaluationResults` container class | Described | Not implemented | Implement class or amend docs | +| Programmatic emitter chain mutation API (`register_emitter` with position) | Described | Only `add_emitter(category, emitter)` simple append | Implement or update docs | +| Ordering hints (`position="after:Name"`) | Described | Spec has `after`/`before` but no resolution logic | Implement resolution or remove from doc | +| Capability flags (`emits_spans`, etc.) | Described | Not implemented | Remove from doc or add flags | +| Async emitters | Explicitly out of scope | Not implemented | ✅ | +| Dynamic hot-swap reconfig | Deferred | Not implemented (except capture refresh partial) | ✅ | + +### 10. Potential Bugs / Risks +1. `after` / `before` fields in `EmitterSpec` unused – user expectations unmet if third-party supplies ordering hints. +2. `MetricsEmitter.role = "metric"` may cause confusion; composite categories use plural name. +3. `ContentEventsEmitter` excludes agent/workflow/task events (commented out) – mismatch with potential future design; silent omission might surprise users. +4. Content capture silently disabled unless experimental semconv opt-in env var includes `gen_ai_latest_experimental`; architecture doc could mislead users expecting capture. +5. Evaluation sampling relies on presence of `invocation.span` and its context; if spans disabled but evaluations desired, sampling may degrade (manager logs debug). Consider fallback to random sampling when no trace id. +6. `_refresh_capture_content` mutates emitters mid-flight; race conditions unlikely (single-thread instrumentation typical) but not guarded by locks. +7. `EvaluationMetricsEmitter` assumes histogram creation succeeded; missing defensive null checks (low risk). +8. Potential attribute duplication: `SpanEmitter` first applies invocation semantic attrs then calls `_apply_gen_ai_semconv_attributes` again in finish; benign but redundant. +9. Legacy evaluation event emission controlled by `OTEL_GENAI_EVALUATION_EVENT_LEGACY` – if accidentally set, could double event volume; consider documenting rate impact. + +### 11. Documentation Gaps To Address in `README.architecture.md` +* Rename / acknowledge `TelemetryHandler` vs `Handler`. +* Update emitter spec field names and supported directives. +* Clarify evaluation emitters (metrics + events) always registered; how aggregation affects only batching, not emitter presence. +* Add sampling explanation + env var for evaluation sample rate. +* Clarify experimental gating for content capture variables. +* Note absence of `EvaluationResults` class (or add it) and current list-based API. +* Add new agentic types + associated metrics histograms. +* Document implementation detail of invocation type filtering (dynamic wrapping of `handles`). +* Clarify single-event content emission vs per-message (and rationale). +* Mention legacy flags (`OTEL_GENAI_EVALUATION_EVENT_LEGACY`, legacy capture envs) and compatibility posture. + +### 12. Recommendations +1. Decide whether to implement ordering resolution for `after`/`before` or remove from spec to prevent confusion. +2. Either rename `MetricsEmitter.role` to `metrics` or explicitly state role is informational and categories are separate. +3. Introduce optional `EvaluationResults` dataclass wrapper for future aggregated metadata (e.g., evaluator count, latency) – low effort. +4. Provide explicit helper API to register emitters programmatically with mode/ordering semantics (thin layer invoking internal registry logic) to match documented extensibility. +5. Enhance documentation with experimental gating explanation for content capture to prevent user confusion. +6. Add unit tests around category overrides (prepend, replace-same-name) and ensure negative cases (unknown emitter) log warnings (currently partial). +7. Consider fallback random sampling in evaluation manager when no trace ID present, to maintain sample rate consistency. +8. Consolidate duplicate attribute application in `SpanEmitter` to reduce overhead (micro-optimization). + +--- +## Appendix: Environment Variables (Observed vs Documented) + +| Variable | Implemented | Doc Status (current) | Action | +|----------|-------------|----------------------|--------| +| OTEL_INSTRUMENTATION_GENAI_EMITTERS | Baseline + extras (span_metric_event) | Partially (older doc) | Update doc with baseline modes | +| OTEL_INSTRUMENTATION_GENAI_EMITTERS_ | Supports append/prepend/replace/replace-category/replace-same-name | Partially (replace-category examples only) | Expand docs | +| OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGES | span/events/both/none + experimental gating | Mentioned (no gating) | Add experimental note | +| OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT(_MODE) | Legacy fallback | Not emphasized | Mark legacy | +| OTEL_INSTRUMENTATION_GENAI_EVALS_EVALUATORS | Full grammar with per-type metric(options) | Summarized | Align examples | +| OTEL_INSTRUMENTATION_GENAI_EVALS_RESULTS_AGGREGATION | Bool | Mentioned | ✅ | +| OTEL_INSTRUMENTATION_GENAI_EVALS_INTERVAL | Poll interval | Omitted in architecture | Add | +| OTEL_INSTRUMENTATION_GENAI_EVALUATION_SAMPLE_RATE | Trace-based sampling ratio | Omitted | Add | +| OTEL_GENAI_EVALUATION_EVENT_LEGACY | Emit legacy evaluation event format | Omitted | Add | + +--- +## Change Log (for this findings doc) +* v1 (2025-10-08): Initial audit results. + +--- +End of implementation findings. diff --git a/util/opentelemetry-util-genai-dev/tests/test_evaluation_manager.py b/util/opentelemetry-util-genai-dev/tests/test_evaluation_manager.py new file mode 100644 index 0000000000..46228f434c --- /dev/null +++ b/util/opentelemetry-util-genai-dev/tests/test_evaluation_manager.py @@ -0,0 +1,67 @@ +from __future__ import annotations + +from opentelemetry.util.genai.evaluators.manager import Manager +from opentelemetry.util.genai.types import EvaluationResult, LLMInvocation + + +class _StubHandler: + def __init__(self) -> None: + self.calls: list[tuple[LLMInvocation, list[EvaluationResult]]] = [] + + def evaluation_results( + self, invocation: LLMInvocation, results: list[EvaluationResult] + ) -> None: + self.calls.append((invocation, list(results))) + + +def _make_manager( + monkeypatch, aggregate: bool +) -> tuple[Manager, _StubHandler]: + monkeypatch.setenv("OTEL_INSTRUMENTATION_GENAI_EVALS_EVALUATORS", "none") + if aggregate: + monkeypatch.setenv( + "OTEL_INSTRUMENTATION_GENAI_EVALS_RESULTS_AGGREGATION", "true" + ) + else: + monkeypatch.delenv( + "OTEL_INSTRUMENTATION_GENAI_EVALS_RESULTS_AGGREGATION", + raising=False, + ) + handler = _StubHandler() + manager = Manager(handler) + manager._evaluators = {"LLMInvocation": []} + manager._aggregate_results = aggregate + return manager, handler + + +def test_manager_emits_single_batch_when_aggregation_enabled(monkeypatch): + manager, handler = _make_manager(monkeypatch, aggregate=True) + invocation = LLMInvocation(request_model="agg-model") + buckets = [ + [EvaluationResult(metric_name="bias", score=0.1)], + [EvaluationResult(metric_name="toxicity", score=0.2)], + ] + + flattened = manager._emit_results(invocation, buckets) + + assert len(handler.calls) == 1 + emitted = handler.calls[0][1] + assert [res.metric_name for res in emitted] == ["bias", "toxicity"] + assert flattened == emitted + + +def test_manager_emits_per_bucket_when_aggregation_disabled(monkeypatch): + manager, handler = _make_manager(monkeypatch, aggregate=False) + invocation = LLMInvocation(request_model="no-agg-model") + buckets = [ + [EvaluationResult(metric_name="bias", score=0.1)], + [EvaluationResult(metric_name="toxicity", score=0.2)], + ] + + flattened = manager._emit_results(invocation, buckets) + + calls = handler.calls + assert len(calls) == 2 + assert [res.metric_name for res in calls[0][1]] == ["bias"] + assert [res.metric_name for res in calls[1][1]] == ["toxicity"] + assert flattened == [item for bucket in buckets for item in bucket] From d9f3bffb382b310ed4c0aee4946bc20d233d4c6a Mon Sep 17 00:00:00 2001 From: Sergey Sergeev Date: Wed, 8 Oct 2025 20:12:29 -0700 Subject: [PATCH 39/55] types refactoring plan --- .../README.refactoring.types.md | 175 ++++++++++++++++++ 1 file changed, 175 insertions(+) create mode 100644 util/opentelemetry-util-genai-dev/README.refactoring.types.md diff --git a/util/opentelemetry-util-genai-dev/README.refactoring.types.md b/util/opentelemetry-util-genai-dev/README.refactoring.types.md new file mode 100644 index 0000000000..7beb62150a --- /dev/null +++ b/util/opentelemetry-util-genai-dev/README.refactoring.types.md @@ -0,0 +1,175 @@ +# GenAI Types Refactor Plan for LangChain Instrumentation + +Status: DRAFT (initial plan) +Owner: (add GitHub handle) +Last Updated: 2025-10-08 + +## 1. Objective +Refactor `opentelemetry-instrumentation-langchain-dev` so it no longer emits spans / attributes directly. Instead it constructs GenAI dataclass instances (`LLMInvocation`, `Workflow`, `AgentInvocation`, `Task`, `ToolCall`) and drives emission exclusively through `opentelemetry.util.genai` (`TelemetryHandler`). This aligns LangChain instrumentation with the implementation‑aligned architecture and enables: centralized emitter configuration, evaluation pipeline reuse, consistent semantic conventions, and simplified vendor flavor extensions. + +### Vendor-Neutral Schema Rule +GenAI dataclasses MUST remain vendor-neutral: +- Do not introduce proprietary or emitter-specific prefixes (e.g. `traceloop.*`) into field names or directly into `attributes` at instrumentation time. +- Fields representing approved semantic convention attributes are annotated via `metadata={"semconv": }`. +- Pre-spec / provisional concepts use neutral descriptive names (e.g. `framework`, `tools`, `input_context`). +- Legacy LangChain / provider metadata gathered during callbacks is stored under a single neutral container key: `attributes['langchain_legacy']` (dictionary) — never `_ls_metadata`, never flattened vendor keys. +- Vendor emitters (e.g. a Traceloop emitter) are solely responsible for mapping neutral dataclass fields + `langchain_legacy` contents into proprietary attribute namespaces. + +Instrumentation MUST NOT set keys beginning with `traceloop.` or raw `ls_*` directly on spans; such projection logic lives only in emitters. + +## 2. Current State (Summary) +The callback handler mixes two patterns: +- Direct OpenTelemetry span creation + attribute setting (legacy Traceloop style) +- Partial adoption of util‑genai (`LLMInvocation` + `AgentInvocation` objects for chat model start/end) +It still: +- Creates spans for chains/tools/LLM completions manually. +- Filters / normalizes params ad hoc (ls_* keys) inside handler. +- Emits request/response prompt data through span attributes or events depending on env gating. + +## 3. Target Model +LangChain callbacks map to GenAI invocation types: +| LangChain Callback | GenAI Type | Notes / Parent Link | +|--------------------|-----------|---------------------| +| `on_chat_model_start` | `LLMInvocation` | `parent_run_id` links to enclosing `AgentInvocation` or `Workflow` if present. | +| `on_llm_start` | (Initial Phase) `LLMInvocation` | Non-chat, treat as completion style; same dataclass. | +| `on_llm_end` | (Finish) same `LLMInvocation` | Populate response fields, tokens, finish reasons then `stop_llm()`. | +| `on_chain_start` (root) | `Workflow` | First chain in a trace becomes a `Workflow`. | +| `on_chain_start` (nested non-agent) | `Task` | Nested chain that is not agent -> `Task` child of workflow / agent. | +| `on_chain_start` (agent detected) | `AgentInvocation` | Use heuristics already present to classify. | +| `on_chain_end` | Finish corresponding object | `stop_workflow` / `stop_task` / `stop_agent`. | +| `on_tool_start` | `Task` (or future `ToolInvocation`) | Represent tool execution as `Task` with `task_type="tool_use"` and name=tool. (Optional future: distinct `ToolInvocation` dataclass). | +| `on_tool_end` | Finish Task | Set `output_data`. | +| `on_*_error` | Fail relevant type | Use `fail_*` API with `Error(message, type)` before discarding state. | + +## 4. Required / Proposed Type Adjustments +| Type | Change | Rationale | +|------|--------|-----------| +| `Workflow` | Add semconv fields? (None needed now) | Keep minimal; semantic conventions for workflows evolving. | +| `AgentInvocation` | Already includes `operation`, `description`, `model`, `tools` | Ensure mapping of agent id/name from run_id and name. | +| `Task` | Reuse for chain/task/tool nodes | Avoid over-proliferation; `task_type` differentiates (chain, tool, internal). | +| `ToolCall` | Already present for LLM tool calls (function calling) | No change; enumeration occurs inside LLM content parts. | +| New (defer) | `ToolInvocation` specialized dataclass | Only if semantics diverge strongly from generic Task. | + +No immediate schema changes required; rely on `attributes` for ancillary *neutral* data (tags, metadata). Add helper to convert LangChain metadata into sanitized `attributes` while placing any legacy `ls_*` / LangChain-specific keys inside `attributes['langchain_legacy']` (a dict). Vendor emitters may later translate those into their own prefixed attributes. + +## 5.

State Management Strategy +Internal maps: +- `_entities: dict[UUID, GenAI]` stores all active objects (workflow, agent, task, llm). +- `_llms: dict[UUID, LLMInvocation]` subset for quick access. +- Optional stacks are derivable via parent links; no explicit stack structure required. +Creation rules: +1. Root `on_chain_start` with no parent -> Workflow. +2. `on_chain_start` with agent heuristic true -> AgentInvocation. +3. Other chain start -> Task(task_type="chain"). +4. `on_tool_start` -> Task(task_type="tool_use"). +5. LLM chat/completion -> LLMInvocation (child of enclosing agent/task/workflow). If parent is AgentInvocation, copy `agent_name/id`. + +## 7. Error Handling +- On `on_*_error`, locate entity, populate any partial fields (e.g., `output_result=str(error)` for Agent, `output_data` for Task) then call `fail_*` with `UtilError(message, type(exception))`. +- Ensure entity removal from `_entities` after fail to avoid memory growth. + +## 8. Token & Content Population +LLM end: +- Extract first generation content + finish_reason. +- Map usage: `prompt_tokens -> input_tokens`, `completion_tokens -> output_tokens`. +- Functions/tool calls: push into `request_functions` if available at start; response tool calls appear as output message parts if LangChain provides them (future – currently minimal). +Tasks / tools: +- Serialize inputs/outputs into `input_data` / `output_data` when JSON-serializable and small (< configurable size threshold, e.g., 8 KB) else put a truncated marker and length attribute. + +## 9. Telemetry Handler Integration Pattern +Provide helper methods: +```python +def _start(entity: GenAI) -> None: ... # dispatches to handler based on isinstance + +def _stop(entity: GenAI) -> None: ... + +def _fail(entity: GenAI, exc: BaseException) -> None: ... +``` +This removes duplication in callback methods. + +## 10. Refactoring Steps / Tasks +(Each should become a PR / changelog entry.) +1. Introduce `_entities` registry + helpers without changing current behavior (internal prep). +2. Replace direct span creation for chat model start/end with existing util calls (already partially done) — remove legacy commented span code. +3. Implement Workflow/Agent/Task creation logic in `on_chain_start` / `on_tool_start`; adjust `on_chain_end`, `on_tool_end` to stop entities instead of ending spans. +4. Migrate error pathways to `_fail` helper invoking handler.fail_*. +5. Remove now-unused span creation utilities for LLM spans (`_create_llm_span`, `set_llm_request`, etc.) or gate behind legacy flag for rollback (since dev branch, removal acceptable). +6. Purge residual attribute setting / association_properties logic (rely on util emitters for semantic attr projection). Retain minimal metadata sanitation to fill `attributes` dict of dataclasses. +7. Add task/tool output serialization & truncation helper. +8. Update tests & examples to validate new pipeline (spans still produced through util emitters, but instrumentation no longer sets them directly). +9. Update docs: this README (plan) and `README.refactoring.telemetry.md` changelog. + +## 11. Risks & Mitigations +| Risk | Mitigation | +|------|------------| +| Loss of vendor-specific attributes (ls_*) | Preserve under neutral container `attributes['langchain_legacy']`; vendor emitter maps to proprietary keys. | +| Missing parent linkage in deeply nested chains | Ensure parent_run_id passed through all callbacks (LangChain provides); add defensive check & fallback to last seen root workflow. | +| Token counts missing for some providers | Leave fields None; metrics emitter tolerates absence. | +| Large input/output payload overhead | Implement truncation; disable capture if exceeds threshold. | + +## 12. Acceptance Criteria +- No direct OpenTelemetry span creation calls remain in handler (except maybe for still-unconverted paths clearly flagged TODO). +- All LangChain lifecycle events create/update GenAI dataclasses and call appropriate handler methods. +- Tests green; manual example emits spans with semantic `gen_ai.*` attributes only (no `ls_*`, no `traceloop.*`). +- README changelog entries created per task. + +## 13.

Prompt for AI Coder (Execute Incrementally) +You are a senior software engineer refactoring LangChain instrumentation to use `opentelemetry.util.genai` dataclasses and handler lifecycle. + +Context: +- Current callback handler file: `instrumentation-genai/opentelemetry-instrumentation-langchain-dev/src/opentelemetry/instrumentation/langchain/callback_handler.py` (see sections creating spans, maintaining `self.spans`, building agents, and LLM invocation logic). +- GenAI dataclasses: `util/opentelemetry-util-genai-dev/src/opentelemetry/util/genai/types.py`. +- Telemetry handler API: `opentelemetry.util.genai.handler.get_telemetry_handler()` and its `start_*`, `stop_*`, `fail_*` methods. + +Requirements: +1. Replace direct span creation for new flows with dataclass creation + handler lifecycle calls. +2. Maintain parent-child relationships using `run_id` / `parent_run_id` fields. +3. Maintain agent context (agent name/id) on descendant `LLMInvocation`s. +4. Preserve legacy metadata in neutral container `attributes['langchain_legacy']` but do not emit vendor attrs on semantic spans. +5. Provide truncation for large serialized inputs/outputs (>8KB) with placeholder `""` and store original length under `attributes['orig_length']`. +6. Remove or gate unused legacy span utilities. +7. Update tests referencing removed span attribute logic. +8. Update this README (Section 13) with each implemented step. +9. Keep commits logically small and labeled with changelog slug. + +Definition of Done: See Acceptance Criteria (Section 12). + +Proceed stepwise; after each step, run tests and update changelog. + +## 15. Open Questions +- Should `ToolInvocation` become its own dataclass? (Defer). +- Workflow semantic conventions not yet standardized—OK to keep minimal for now. + +--- +End of document.
