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.

Enable it via an environment variable so downstream users can opt into backward-compatible telemetry without forking. + +## Summary +The current development callback handler (`opentelemetry-instrumentation-langchain-dev`) switched from in-place span construction (Traceloop style) to delegating LLM lifecycle to `TelemetryHandler` in `opentelemetry-util-genai-dev`. 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.

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/LICENSE b/util/opentelemetry-util-genai-dev/LICENSE new file mode 100644 index 0000000000..261eeb9e9f --- /dev/null +++ b/util/opentelemetry-util-genai-dev/LICENSE @@ -0,0 +1,201 @@ + Apache License + Version 2.0, January 2004 + http://www.apache.org/licenses/ + + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION + + 1.

For an audit of deltas between the original vision and code, see `README.implementation-findings.md`. + +## 1. Goals (Why this utility exists) +Provide a stable, extensible core abstraction (GenAI Types + TelemetryHandler + CompositeEmitter + Evaluator hooks) separating *instrumentation capture* from *telemetry flavor emission* so that: +- Instrumentation authors create neutral GenAI data objects once. +- Different telemetry flavors (semantic conventions, vendor enrichments, events vs attributes, aggregated evaluation results, cost / agent metrics) are produced by pluggable emitters without touching instrumentation code. +- Evaluations (LLM-as-a-judge, quality metrics) run asynchronously and re-emit results through the same handler/emitter pipeline. +- Third parties can add / replace / augment emitters in well-defined category chains. +- Configuration is primarily environment-variable driven; complexity is opt-in. + +Non-goal: Replace the OpenTelemetry SDK pipeline. Emitters sit *above* the SDK using public Span / Metrics / Logs / Events APIs. + +## 2. Core Concepts +### 2.1 GenAI Types (Data Model) +Implemented dataclasses (in `types.py`): +- `LLMInvocation` +- `EmbeddingInvocation` +- `Workflow` +- `AgentInvocation` +- `Task` +- `ToolCall` +- `EvaluationResult` (atomic) + +Planned (not yet implemented): `RetrievalInvocation`, `PlannerInvocation`, aggregated `EvaluationResults` wrapper (currently lists of `EvaluationResult` are passed directly). + +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. + +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). + +Messages: `InputMessage` / `OutputMessage` each hold `role` and `parts` (which may be `Text`, `ToolCall`, `ToolCallResponse`, or arbitrary parts). Output messages include `finish_reason`. + +`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. + +### 2.2 TelemetryHandler +`TelemetryHandler` (formerly referred to as `Handler`) orchestrates lifecycle & evaluation emission. + +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 / 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 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`. + +`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 +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). + +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 EmitterSpec & Discovery +Entry point group: `opentelemetry_util_genai_emitters` (vendor packages contribute specs). + +`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) + +Ordering hints will either gain a resolver or be removed (open item). + +### 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`). + +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:`. + +### 3.5 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 +Supported modes: `append`, `prepend`, `replace-category` (alias `replace`), `replace-same-name`. Ordering hints (`after` / `before`) are present but inactive. + +### 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). + +## 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. + +### 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`. + +### 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). + +### 4.4 Evaluation Emitters +Always present: +- `EvaluationMetricsEmitter` – fixed histograms: + - `gen_ai.evaluation.relevance` + - `gen_ai.evaluation.hallucination` + - `gen_ai.evaluation.sentiment` + - `gen_ai.evaluation.toxicity` + - `gen_ai.evaluation.bias` + (Legacy dynamic `gen_ai.evaluation.score.` instruments removed.) +- `EvaluationEventsEmitter` – event per `EvaluationResult`; optional legacy variant via `OTEL_GENAI_EVALUATION_EVENT_LEGACY`. + +Aggregation flag affects batching only (emitters remain active either way). + +Emitted attributes (core): +- `gen_ai.evaluation.name` – metric name +- `gen_ai.evaluation.score.value` – numeric score (events only; histogram carries values) +- `gen_ai.evaluation.score.label` – categorical label (pass/fail/neutral/etc.) +- `gen_ai.evaluation.score.units` – units of the numeric score (currently `score`) +- `gen_ai.evaluation.passed` – boolean derived when label clearly indicates pass/fail (e.g. `pass`, `success`, `fail`); numeric-only heuristic currently disabled to prevent ambiguous semantics +- Agent/workflow identity: `gen_ai.agent.name`, `gen_ai.agent.id`, `gen_ai.workflow.id` when available. + +## 5. Third-Party Emitters (External Packages) +- Traceloop span compatibility (`opentelemetry-util-genai-emitters-traceloop`). +- Splunk evaluation aggregation / extra metrics (`opentelemetry-util-genai-emitters-splunk`). + +## 6.

Evaluators Integration +Entry point group: `opentelemetry_util_genai_evaluators`. + +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.

Compares actual implementation with the reference architecture in `README.architecture.md` and high-level snapshot in `../README.architecture.packages.md`. + +--- +## Summary +The implementation broadly aligns with the intended layered design (Types → Handler → CompositeEmitter → Emitters / Evaluation Manager). 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/README.refactoring.emitters.demo-scenarios.md b/util/opentelemetry-util-genai-dev/README.refactoring.emitters.demo-scenarios.md new file mode 100644 index 0000000000..b533113bb8 --- /dev/null +++ b/util/opentelemetry-util-genai-dev/README.refactoring.emitters.demo-scenarios.md @@ -0,0 +1,285 @@ +# GenAI Emitters Refactor Demo Scenarios + +This document extends the base demo guide and walks through distinct scenarios mapped to the reference architecture: + +Scenarios: +1.

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. Gap Analysis (Detailed) +| Aspect | Current | Target | Gap / Action | +|--------|---------|--------|--------------| +| Protocol name | `GeneratorProtocol.start/finish/error` | `EmitterProtocol.on_start/on_end/on_evaluation_results` | Rename + adapt method names + add evaluation handler layering | +| Composite orchestrator | `CompositeGenerator` ad-hoc role ordering | `CompositeEmitter` category-based lists (span, metrics, content_events, evaluation) | Implement new class; deprecate old; map existing emitters into categories | +| Env var namespace | `OTEL_INSTRUMENTATION_GENAI_*` | Same | No change needed (retain existing prefix) | +| Configuration parsing location | Inside `TelemetryHandler` | Inside `CompositeEmitter` (handler only calls builder) | Move logic; keep handler minimal | +| Registration/discovery | Custom plugin loader + `extra_emitters` in settings | Entry points returning `EmitterSpec` list | Replace plugin loader path with unified loader; migrate traceloop & splunk packages | +| Traceloop emitter placement | In core dev package | External package | **Completed:** emitted by `opentelemetry-util-genai-emitters-traceloop` | +| Splunk emission pattern | Basic example emitter (not full spec) | Replace evaluation category + append metrics | Expand Splunk package to implement evaluation aggregator + metrics extender | +| Evaluation emission | Separate `CompositeEvaluationEmitter` internal | Part of unified evaluation emitters chain | Fold evaluation emitters into CompositeEmitter evaluation category | +| Message content capture control | Mixed span/events logic in handler refresh | Config-driven category toggles & per-emitter flags | Abstract message capture decisions into emitter initialization & runtime settings | +| Invocation type filtering | `handles()` method per emitter | `invocation_types` list in spec | Provide adapter: wrap old `handles` or generate spec with invocation_types | +| Error isolation | Partial try/except (only error stage) | Wrap each call per emitter & emit counter | Add uniform wrapper & metric/log hook | +| Naming (`generator_kind`) | Terms: generator, generator_kind | Terms: emitter, categories | Rename config keys & adapt tests | +| Tests | Extensive tests referencing generators & traceloop_compat | New tests for registration, ordering, replacement, invocation filtering | Rewrite / remove obsolete tests | + +--- +## 5. 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.

`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.refactoring.telemetry.md b/util/opentelemetry-util-genai-dev/README.refactoring.telemetry.md new file mode 100644 index 0000000000..41e17e6bff --- /dev/null +++ b/util/opentelemetry-util-genai-dev/README.refactoring.telemetry.md @@ -0,0 +1,302 @@ +# GenAI Telemetry Refactoring: LLMInvocation Span Flavors (Semantic Conventions vs Traceloop) + +> Status: DRAFT (bootstrap commit) +> Owner: (add GitHub handle) +> Last Updated: 2025-10-06 + +This document tracks the refactoring to unify the `LLMInvocation` data model and emitters so that: + +1.

Refactoring Objectives + +A. Data Model +- Ensure every semconv attribute we emit is backed by a dedicated dataclass field with `metadata={'semconv': ...}` (already largely true). +- ✅ Removed `chat_generations`: `output_messages` is the authoritative response container. +- 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 +- Resolved: `chat_generations` removed; 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. +- Issue: Manual LangChain example (`examples/manual/main.py`) currently produces no telemetry events in the collector; root cause under investigation. +- Question: Should `user` (custom JSON) be standardized?

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. + +### Recent Progress Snapshot +- Replaced internal span maps with `_entities`/`_llms` registries and routed lifecycle calls through `TelemetryHandler`. +- Chain, tool, agent, and LLM callbacks now build neutral GenAI dataclasses and preserve `langchain_legacy` metadata. +- Metrics emitters attach span context when recording so exemplars are emitted (still validating via tests). + +### Outstanding Issues +- `tests/test_langchain_llm.py::test_langchain_call` currently fails because token usage exemplars are missing in replayed metrics. Investigate histogram context propagation. +- `tests/test_langchain_llm.py::test_langchain_call_with_tools` produces no spans under VCR replay with the new entity pipeline; trace suppression or parent linkage needs debugging. +- Pytest runs inside the sandbox require disabling the rerunfailures plugin; outside-sandbox verification still pending. + +## 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. Event → GenAI Lifecycle Mapping +``` +chat start -> build LLMInvocation -> handler.start_llm +chat end -> populate response_* tokens -> handler.stop_llm +chain start (root, non-agent) -> build Workflow -> handler.start_workflow +chain start (agent) -> build AgentInvocation -> handler.start_agent +chain start (nested non-agent) -> build Task(task_type="chain") -> handler.start_task +tool start -> build Task(task_type="tool_use") -> handler.start_task +chain/tool end -> set outputs -> handler.stop_*(obj) +errors (llm/chain/tool/agent) -> handler.fail_*(obj, Error) +``` +Parent propagation: Keep dict[run_id -> GenAI] similar to existing `_invocations` / `_agents`; unify under `_entities` with a typed wrapper so we can look up parent quickly and populate `parent_run_id`. + +## 6. 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.

+- Provide test harness simulating traceloop plugin returning override span emitter. + +### Phase 6: Splunk Evaluation Aggregation Plugin Support +- Define aggregated event schema contract doc. +- Implement fallback aggregator if plugin present (core must NOT emit standard eval events when override active). +- Tests: ensure only single aggregated event emitted; no per-result duplication. + +### Phase 7: Harden & Document +- Add metrics for internal instrumentation (optional): counts of invocations, failures, evaluation count. +- Provide upgrade guide referencing semconv version. +- Add ADR cross-links. + +## 7.

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?

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. For `span_metric_event`, content is emitted as events; for others, as span attributes. + +### 5.6 Plugin Overrides +Entry points: +- `opentelemetry_genai.generators` → emitters +- `opentelemetry_genai.evaluators` → evaluators + +Override resolution: +1. 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.

Acceptance Criteria +| ID | Criteria | +|----|----------| +| A1 | All existing tests pass using emission path with legacy disabled. | +| A2 | Setting each flavor yields correct distribution of content (attrs vs events). | +| A3 | Metrics & events emitted only while invocation span active (verified via context assertions). | +| A4 | Error path emits span with error attrs, no metrics/events/evals (except allowed input capture). | +| A5 | Plugin override unit tests demonstrate: traceloop span override & splunk evaluation aggregation. | +| A6 | Legacy generator imports produce deprecation warning only, no functional divergence. | +| A7 | Documentation updated (README section + ADRs) and explains migration. | +| A8 | Codebase free of concrete per-type generator classes (except stubs). | + +## 9.

Risks & Mitigations +| Risk | Mitigation | +|------|------------| +| Plugin conflict | Deterministic first-wins override + logged warning. | +| Performance overhead | Emitters minimal; early bail on roles not handling object type. | +| API churn for external adopters | Maintain stable handler interface; deprecate gradually. | +| Missing span context during emission | Central orchestrator ensures active span; test assertions. | +| Schema drift (vendor) | Contract tests + semconv compliance checklist. | + +## 12. Open Questions +- Should evaluation aggregation optionally still set summary span attrs when overridden? (Default: yes.) +- Need standardized hashing algorithm for content summaries? (Chosen: SHA-256; configurable later.) +- Truncation thresholds for large content? (Add config: `OTEL_GENAI_CONTENT_TRUNCATE_BYTES`.) + +## 13. Implementation Notes +- Use a lightweight `EmitterContext` dataclass carrying tracer, span, config, timing, and scratch fields (e.g. token counts). +- Provide `register_probe_emitter(test_recorder)` utility for ordering tests. +- Avoid coupling emitters to evaluation internals; evaluation results emitted as separate domain objects. + +## 14. Deprecation Strategy +- First release with emission path: emit `DeprecationWarning` on import from `opentelemetry.util.genai.generators` pointing to ADR 0002. +- After one minor version: remove stubs (subject to semantic versioning policy; if <1.0, document in CHANGELOG). + +## 15.

+====================================== + +This package provides the legacy Traceloop-compatible span emitter that was +previously bundled with ``opentelemetry-util-genai``. It exposes an entry point +named ``traceloop`` under ``opentelemetry_util_genai_emitters`` so that the +refactored composite emitter can discover and append the Traceloop span logic +at runtime. + +Installation +------------ + +.. code-block:: bash + + pip install opentelemetry-util-genai-emitters-traceloop + +When working from the refactor branch you can use the editable install: + +.. code-block:: bash + + pip install -e util/opentelemetry-util-genai-emitters-traceloop + +Usage +----- + +Add ``traceloop_compat`` to ``OTEL_INSTRUMENTATION_GENAI_EMITTERS`` (or the +category-specific environment variables) once the package is installed: + +.. code-block:: bash + + export OTEL_INSTRUMENTATION_GENAI_EMITTERS="span_metric_event,traceloop_compat" + +The emitter will append a span that mirrors the original Traceloop LangChain +telemetry, including optional message content capture when span or event +content capture is enabled in ``opentelemetry-util-genai``. + +Tests +----- +Run the

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 new file mode 100644 index 0000000000..825b76c5be --- /dev/null +++ b/util/opentelemetry-util-genai-evals-deepeval/pyproject.toml @@ -0,0 +1,54 @@ +[build-system] +requires = ["hatchling"] +build-backend = "hatchling.build" + +[project] +name = "opentelemetry-util-genai-evals-deepeval" +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_util_genai_evaluators] +deepeval = "opentelemetry.util.evaluator.deepeval:_REGISTRATION" + +[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/evaluator/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-evals-deepeval/pytest.ini b/util/opentelemetry-util-genai-evals-deepeval/pytest.ini new file mode 100644 index 0000000000..8300e5055e --- /dev/null +++ b/util/opentelemetry-util-genai-evals-deepeval/pytest.ini @@ -0,0 +1,4 @@ +[pytest] +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 new file mode 100644 index 0000000000..6899628f8b --- /dev/null +++ b/util/opentelemetry-util-genai-evals-deepeval/src/opentelemetry/util/evaluator/__init__.py @@ -0,0 +1,19 @@ +# Copyright The OpenTelemetry Authors +# +# Licensed under the Apache License, Version 2.0 (the "License");
