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.

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;

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). Defer class explosions and multi-package fragmentation until real, measurable divergence appears. This keeps iteration speed high, lowers cognitive load, and reduces risk of locking into an inflexible inheritance design while semantic conventions are still stabilizing. + +## 18. Optional Next Additions (If You Want Quick Wins) +- Add a simple logging emitter (debug-level) to validate composite fan-out. +- Provide a sample evaluator that calculates prompt/response token delta or length-based heuristic, just to exercise the pipeline. +- Include an internal metrics counter (number of invocations, failures) to dogfood metric emission design later. + +--- +Feel free to iterate on any section; this document can evolve into an ADR reference. + diff --git a/util/opentelemetry-util-genai-dev/GENERATORS.rst b/util/opentelemetry-util-genai-dev/GENERATORS.rst deleted file mode 100644 index 46eff38963..0000000000 --- a/util/opentelemetry-util-genai-dev/GENERATORS.rst +++ /dev/null @@ -1,175 +0,0 @@ -GenAI Telemetry Generators -========================== - -This document describes strategy implementations ("generators") that translate a logical GenAI model -invocation (``LLMInvocation``) into OpenTelemetry signals. - -Generator Matrix ----------------- -The following summarizes capabilities (✅ = provided, ❌ = not provided; "Optional" = controlled by -content capture mode / configuration): - -======================== ===== ======= ====================== ========================= ================== -Generator Spans Metrics Structured Log Events Message Content Capture Intended Stability -======================== ===== ======= ====================== ========================= ================== -SpanGenerator ✅ ❌ ❌ Optional (env+flag) Default / earliest -SpanMetricGenerator ✅ ✅ ❌ Optional Experimental -SpanMetricEventGenerator ✅ ✅ ✅ (choices & inputs) Optional Experimental -======================== ===== ======= ====================== ========================= ================== - -Note: Only ``SpanGenerator`` is presently wired by ``TelemetryHandler`` for general usage.

Context +Earlier iterations introduced a `generators/` package with multiple base and concrete *Generator* classes (span, metric, event, evaluation, etc.). Ongoing evolution showed: +- The class hierarchy added boilerplate without delivering the flexibility it was designed for. +- Real divergence of behavior is emerging mainly across "telemetry flavor" (span | span_metric | span_metric_event) and vendor/plugin extensions (Traceloop, Splunk evaluation aggregation). +- We need a leaner, composition-based emission layer that centralizes ordering, keeps spans open while emitting derived telemetry, and enables external overrides (plugins) without subclass proliferation. + +This ADR finalizes the direction to eliminate legacy generator classes and move all telemetry production logic into composable emitters inside an `emission/` module. + +## 2. Problem Statement +We must: +1. Support 3 flavors of GenAI telemetry with clear data capture semantics. +2. Allow vendor-specific span augmentation (Traceloop) without sacrificing semantic convention compatibility. +3. Allow a proprietary evaluation results aggregation event (Splunk) that replaces default per-result emission. +4. Guarantee that metrics and events are emitted in the active span context. +5. Provide a stable plugin/override mechanism and migration path. +6. Reduce maintenance burden (remove deep inheritance & redundant per-type generator classes). + +## 3. 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. Non-Goals +- Streaming/partial evaluation emission (future consideration). +- Asynchronous batching of metrics/events. +- Full metrics parity for evaluation scores (can be gated later). + +## 5. Key Concepts +### 5.1 Domain Types +Remain pure (no emission logic): `LLMInvocation`, `EmbeddingInvocation`, `ToolCall`, `EvaluationResult`, `Error`, and future extensions. + +### 5.2 Emitters +Role-oriented small components implementing: +```python +class EmitterProtocol(Protocol): + role: str # span | metric | content_event | evaluation_result + name: str + handles: set[type] + override: bool # if true, replaces all defaults for its role when selected + def start(self, obj, ctx): ... + def finish(self, obj, ctx): ... + def error(self, obj, err, ctx): ... +``` +Only methods relevant to lifecycle need non-noop implementations per role. + +### 5.3 Composite Orchestrator +`CompositeGenerator` (or `EmissionOrchestrator`) maintains ordered list of emitters and span lifecycle control. Ordering constraints: +1. span.start +2. (optional) content_event.start (input side) for `span_metric_event` flavor +3. metric.start (if any start-time metrics) +4. User completes invocation +5. metric.finish +6. content_event.finish (output, tool calls) +7. evaluation_result emission (start/finish per result OR aggregated) while span active +8. span.finish + +Errors short-circuit after span.error → span.finish (no metrics/events/evaluations unless minimal input capture allowed). + +### 5.4 Flavors +| Flavor | Metrics | Content Events | Content on Span | Evaluation Result Default | +|--------|---------|----------------|-----------------|---------------------------| +| span | No | No | Yes (if capture enabled) | Span attributes per result | +| span_metric | Yes | No | Yes | Span attrs + (optional) metrics | +| span_metric_event | Yes | Yes | Minimal summary only | Events per result (unless overridden) | + +### 5.5 Data Capture Modes +`OTEL_GENAI_CAPTURE_CONTENT=none|input|output|full` determines inclusion of input/output.

Load defaults per role. +2. Load plugins. +3. Apply explicit `OTEL_GENAI_PLUGIN_OVERRIDES` (e.g. `span:traceloop,evaluation_result:splunk`). +4. Apply implicit convenience variable `OTEL_GENAI_SPAN_VENDOR=traceloop` if set. +5. For each role: if one or more selected emitters have `override=True`, keep first and drop others (log warning if >1 different override candidates). + +### 5.7 Vendor Examples +- Traceloop Span Emitter: role=span, override or selected by vendor var; adds `traceloop.*` attrs + standard semconv attributes. +- Splunk Evaluation Emitter: role=evaluation_result, override; emits a single aggregated event `gen_ai.evaluations` summarizing all results. + +### 5.8 Evaluation Flow +Evaluators run after invocation finish (success only): +``` +results = [r for ev in evaluators for r in ev.evaluate(invocation)] +for r in results: + composite.start(r) # if per-result path + composite.finish(r) +# OR aggregated emitter receives full list (implementation-defined) +``` +Aggregation is enabled by an emitter declaring it handles list-of-results input or by override semantics. + +## 6.
