This works because: + +1. **BaseObserver is Public API**: Pipecat's `BaseObserver` is designed for external extensions +2. **PipelineTask Accepts Observers**: Tasks can be initialized with custom observers +3. **Dynamic Registration**: `task.add_observer(observer)` works at runtime + +### Implementation Approaches + +#### Approach 1: Automatic Injection (Recommended) + +Wrap `PipelineTask.__init__` to automatically inject our observer: + +```python +# All code in openinference-instrumentation-pipecat package +from pipecat.pipeline.task import PipelineTask +from pipecat.observers.base_observer import BaseObserver + +class OpenInferenceObserver(BaseObserver): + """Our observer -

users just call `PipecatInstrumentor().instrument()` +- **No application code changes** - works with existing Pipecat code +- **Clean migration** from manual tracing example +- **Consistent with other instrumentations** (OpenAI, LangChain patterns) + +**Disadvantages:** +- Wraps framework initialization (slightly invasive, but still using public API) +- One shared observer instance across all tasks (may need thread safety) + +#### Approach 2: Manual Observer Registration + +Users explicitly add the observer to their tasks: + +```python +# User's application code +from openinference.instrumentation.pipecat import PipecatInstrumentor, OpenInferenceObserver + +# Instrument (sets up tracer, config) +instrumentor = PipecatInstrumentor() +instrumentor.instrument(tracer_provider=tracer_provider) + +# User creates observer and adds it manually +observer = instrumentor.create_observer() # Factory method +task = PipelineTask(pipeline, observers=[observer]) +``` + +**Advantages:** +- **Simpler implementation** - no monkey-patching needed +- **Explicit control** - users see exactly what's being added +- **Multiple observers** - easy to combine with custom observers +- **Thread-safe** - each task gets its own observer instance + +**Disadvantages:** +- **Requires code changes** - users must modify their applications +- **Less automatic** - not as seamless as other instrumentations +- **Migration friction** - harder to adopt + +#### Recommended: Hybrid Approach + +**Default to automatic injection, but expose observer for manual use:** + +```python +# Automatic (default) - most users +from openinference.instrumentation.pipecat import PipecatInstrumentor + +PipecatInstrumentor().instrument(tracer_provider=provider) +task = PipelineTask(pipeline) # Observer auto-injected ✅ + +# Manual (advanced users) - explicit control +from openinference.instrumentation.pipecat import PipecatInstrumentor, OpenInferenceObserver + +instrumentor = PipecatInstrumentor() +instrumentor.instrument(tracer_provider=provider) + +# Create observer manually for custom configuration or multiple observers +observer = OpenInferenceObserver.create_from_instrumentor(instrumentor) +custom_observer = MyCustomObserver() +task = PipelineTask(pipeline, observers=[observer, custom_observer]) + +# Or disable automatic injection +instrumentor.instrument(tracer_provider=provider, auto_inject=False) +observer = instrumentor.create_observer() +task = PipelineTask(pipeline, observers=[observer]) +``` + +**Benefits of Hybrid Approach:** +- **Automatic by default** - seamless instrumentation for most users +- **Manual override** - advanced users can disable auto-injection +- **Multi-observer support** - combine with custom observers +- **Configuration flexibility** - per-task observer configuration when needed + +### Thread Safety Considerations + +**Challenge**: If we auto-inject a single observer instance, it will be shared across all `PipelineTask` instances. + +**Solutions**: + +1. **Observer Factory Pattern** (Recommended): +```python +class _TaskInitWrapper: + def __init__(self, tracer: OITracer, config: TraceConfig): + self._tracer = tracer + self._config = config + + def __call__(self, wrapped, instance, args, kwargs): + wrapped(*args, **kwargs) + + # Create NEW observer instance for each task + observer = OpenInferenceObserver( + tracer=self._tracer, + config=self._config + ) + instance.add_observer(observer) +``` + +2. **Thread-Safe Shared Observer**: +```python +class OpenInferenceObserver(BaseObserver): + def __init__(self, tracer, config): + self._tracer = tracer + self._config = config + self._task_contexts = {} # task_id -> context + self._lock = asyncio.Lock() + + async def on_push_frame(self, data): + task_id = id(data.source._parent_task) # Get task identifier + async with self._lock: + # Handle per-task state safely + pass +``` + +**Recommendation**: Use **Observer Factory Pattern** to create one observer per task. This is cleaner, safer, and aligns with the principle that each task represents an independent conversation/session. + +### Implementation Summary + +**What gets added to Pipecat**: Nothing ✅ +**What stays in OpenInference package**: Everything ✅ + +``` +openinference-instrumentation-pipecat/ +└── src/openinference/instrumentation/pipecat/ + ├── __init__.py #

(factory pattern) +- Service spans finish on `EndFrame` or `ErrorFrame` +- Turn spans finish on `BotStoppedSpeakingFrame` or interruption +- Works with all service providers (OpenAI, Anthropic, ElevenLabs, Deepgram, etc.) + +## Revised Requirements & Implementation Plan + +### Key Requirements (Updated) + +Based on discussion and analysis of Pipecat's extensive frame types (100+ frames across categories like LLM, TTS, STT, audio, control, function calling, etc.), the following requirements have been identified: + +#### 1. **Proper Span Hierarchy & Parent-Child Relationships** + - **Session Level**: All turns within a conversation share a session ID + - **Turn Level**: Root span for each interaction showing overall input/output + - **Service Level**: Child spans for LLM, TTS, STT operations within a turn + - **LLM Specifics**: When LLM is involved, use `OPENINFERENCE_SPAN_KIND = "LLM"` and extract messages + +#### 2. **Session Management** + - Utilize `using_session(session_id)` context manager from openinference-instrumentation + - Session ID propagated via OpenTelemetry context to all child spans + - PipelineTask `conversation_id` parameter maps to session.id attribute + +#### 3. **LLM Frame Handling** + - Detect LLM-related frames: `LLMMessagesFrame`, `LLMMessagesAppendFrame`, `LLMFullResponseStartFrame`, etc. + - Extract messages and use proper OpenInference LLM span kind + - Capture LLM-specific attributes (model, messages, function calls, etc.) + +#### 4. **Generic Frame Handling** + - Don't create unique handlers for every frame type (too many!) + - Capture frame class name as attribute for all frames + - Extract properties based on frame type pattern matching: + - Text content (TextFrame, TranscriptionFrame, etc.) + - Audio metadata (AudioRawFrame variants) + - Control signals (StartFrame, EndFrame, ErrorFrame) + - Function calling (FunctionCallFromLLM, FunctionCallResultFrame) + - Gracefully handle unknown frame types + +#### 5. **Span Hierarchy Example** +``` +Session Span (session.id = "conv-123") + └─> Turn Span 1 (conversation.turn_number = 1, input = "Hello", output = "Hi there!") + ├─> STT Span (service.name = "openai", frame.type = "TranscriptionFrame") + ├─> LLM Span (SPAN_KIND = "LLM", model = "gpt-4", messages = [...]) + │ └─> OpenAI ChatCompletion Span (from openai instrumentation) + └─> TTS Span (service.name = "elevenlabs", voice.id = "...) + └─> Turn Span 2 (conversation.turn_number = 2, ...) + └─> ... +``` + +### Implementation Tasks + +#### ❌ **NOT DONE: Session-Level Span Management** +**Current State**: No session span, turns are not connected +**Required Changes**: +1. Create session span when observer is initialized with `conversation_id` +2. Use `using_session(conversation_id)` to propagate session.id +3. Make all turn spans children of session span via OpenTelemetry context +4. Session span lifecycle: + - Start: When first turn begins OR when observer is created + - End: When pipeline task completes OR explicit session end + +#### ❌ **NOT DONE: Proper Parent-Child Span Relationships** +**Current State**: Spans are created independently, no parent-child links +**Required Changes**: +1. Use `trace_api.use_span()` context manager to set active span +2. Turn spans created within session span context +3. Service spans (LLM, TTS, STT) created within turn span context +4. Verify span hierarchy via `span.parent.span_id` in tests + +#### ❌ **NOT DONE: LLM Span Kind & Message Extraction** +**Current State**: LLM spans use `CHAIN` span kind, don't extract messages +**Required Changes**: +1. Detect LLM service type properly (already done) +2. Change span kind to `OpenInferenceSpanKindValues.LLM` for LLM operations +3. Extract messages from LLM frames: + - `LLMMessagesFrame` → full message list + - `LLMMessagesAppendFrame` → appended messages + - `LLMFullResponseStartFrame` / `LLMFullResponseEndFrame` → response tracking +4. Use `get_llm_input_message_attributes()` and `get_llm_output_message_attributes()` + +#### ✅ **PARTIALLY DONE: Generic Frame Attribute Extraction** +**Current State**: Basic frame attributes extracted (text, some metadata) +**Required Enhancements**: +1. Always capture `frame.type` = frame.__class__.__name__ +2. Pattern-based extraction: + ```python + # Text frames + if hasattr(frame, 'text') and frame.text: + yield SpanAttributes.INPUT_VALUE or OUTPUT_VALUE, frame.text + + # Audio frames + if hasattr(frame, 'audio') and hasattr(frame, 'sample_rate'): + yield "audio.sample_rate", frame.sample_rate + + # Function calling + if isinstance(frame, FunctionCallFromLLM): + yield "tool.name", frame.function_name + yield "tool.arguments", frame.arguments + ``` +3.

Implementation Plan - -## Executive Summary - -This document outlines the plan to generalize the current manual tracing implementation for Pipecat into a proper OpenInference instrumentation package that follows established patterns from other OpenInference instrumentations (OpenAI, LangChain, LlamaIndex). - -## Current State Analysis - -### Existing Example Implementation - -The current tracing example ([examples/trace/tracing_setup.py](examples/trace/tracing_setup.py)) uses a **manual monkey-patching approach** with the following characteristics: - -1. **Manual Span Creation**: Directly patches `OpenAILLMService.process_frame`, `OpenAISTTService._transcribe`, and `OpenAITTSService.run_tts` -2. **Turn-Based Tracing**: Implements a `TurnTracker` class to manage conversation turns as separate traces -3. **Trace Structure**: Creates hierarchical traces: - - Root: `Interaction` span (one per user turn) - - Children: `STT` → `LLM` → `TTS` spans - - Auto-instrumented OpenAI spans nested under appropriate parents -4. **OpenInference Conventions**: Uses `CHAIN` span kind for manual operations, relies on OpenAI auto-instrumentation for `LLM` spans - -### Key Insights from Current Implementation - -**Strengths:** -- Captures full conversation context (user input → bot output) -- Proper parent-child relationships between pipeline phases -- Handles streaming and async operations correctly -- Integrates well with existing OpenAI instrumentation - -**Limitations:** -- Hardcoded for OpenAI services only -- Manual patching is fragile and library-specific -- No generalization to other LLM/TTS/STT providers -- Requires deep knowledge of Pipecat internals -- Not reusable across different Pipecat applications - -## OpenInference Instrumentation Patterns - -### Pattern Analysis from Existing Instrumentations - -#### 1. OpenAI Instrumentation Pattern -**File**: [openinference-instrumentation-openai](../openinference-instrumentation-openai/src/openinference/instrumentation/openai/__init__.py) - -**Key Characteristics:** -- **BaseInstrumentor**: Extends OpenTelemetry's `BaseInstrumentor` -- **Wrapping Strategy**: Uses `wrapt.wrap_function_wrapper` to intercept method calls -- **Target**: Single method interception - `OpenAI.request()` and `AsyncOpenAI.request()` -- **Span Management**: - - Creates spans before method execution - - Handles streaming responses by monkey-patching response objects - - Extracts attributes from both request and response -- **Context Propagation**: Uses OpenTelemetry context API for proper parent-child relationships - -**Code Pattern:** -```python -class OpenAIInstrumentor(BaseInstrumentor): - def _instrument(self, **kwargs): - tracer = OITracer(...) - wrap_function_wrapper( - module="openai", - name="OpenAI.request", - wrapper=_Request(tracer=tracer, openai=openai) - ) -``` - -#### 2. LangChain Instrumentation Pattern -**File**: [openinference-instrumentation-langchain](../openinference-instrumentation-langchain/src/openinference/instrumentation/langchain/__init__.py) - -**Key Characteristics:** -- **Callback-Based**: Integrates with LangChain's existing callback system -- **Hook Point**: Wraps `BaseCallbackManager.__init__` to inject custom callback handler -- **Tracer Integration**: Adds `OpenInferenceTracer` to all callback managers -- **Run Tracking**: Maintains a map of run IDs to spans for context propagation -- **Non-Invasive**: Works through LangChain's designed extension points - -**Code Pattern:** -```python -class LangChainInstrumentor(BaseInstrumentor): - def _instrument(self, **kwargs): - tracer = OpenInferenceTracer(...) - wrap_function_wrapper( - module="langchain_core.callbacks", - name="BaseCallbackManager.__init__", - wrapper=_BaseCallbackManagerInit(tracer) - ) -``` - -#### 3. LlamaIndex Instrumentation Pattern -**File**: [openinference-instrumentation-llama-index](../openinference-instrumentation-llama-index/src/openinference/instrumentation/llama_index/__init__.py) - -**Key Characteristics:** -- **Event/Span Handlers**: Uses LlamaIndex's built-in instrumentation dispatcher -- **Handler Registration**: Registers custom `_SpanHandler` and `EventHandler` with dispatcher -- **Framework Integration**: Leverages library's native instrumentation hooks -- **No Monkey-Patching**: Uses official extension points instead - -**Code Pattern:** -```python -class LlamaIndexInstrumentor(BaseInstrumentor): - def _instrument(self, **kwargs): - dispatcher = get_dispatcher() - span_handler = _SpanHandler(tracer=tracer) - event_handler = EventHandler(span_handler=span_handler) - dispatcher.add_span_handler(span_handler) - dispatcher.add_event_handler(event_handler) -``` - -### Common Patterns Across All Instrumentations - -1. **BaseInstrumentor Inheritance**: All extend `opentelemetry.instrumentation.instrumentor.BaseInstrumentor` -2. **OITracer Usage**: Wrap OTEL tracer with `openinference.instrumentation.OITracer` -3. **TraceConfig Support**: Accept optional `TraceConfig` for customization -4. **Clean Uninstrumentation**: Implement `_uninstrument()` to restore original behavior -5. **Attribute Extraction**: Separate request/response attribute extraction logic -6. **Context Preservation**: Maintain OpenTelemetry context for proper span hierarchy - -## Pipecat Architecture Analysis - -### Core Architecture Overview - -Pipecat is built on a **frame-based processing model** where: -- All data flows through the pipeline as `Frame` objects -- Processors are linked sequentially and process frames asynchronously -- Frames can flow both downstream (source → sink) and upstream (sink → source) -- System frames have priority over data frames - -### Base Classes - Detailed Analysis - -#### 1. FrameProcessor (`src/pipecat/processors/frame_processor.py`) - -**Inheritance**: `FrameProcessor` extends `BaseObject` - -**Key Methods for Instrumentation**: -- `__init__(*, name, enable_direct_mode, metrics, **kwargs)`: Initialization hook -- `process_frame(frame, direction)`: Main frame processing dispatcher -- `queue_frame(frame, direction, callback)`: Frame queueing with cancellation support -- `push_frame(frame, direction)`: Pushes frames to next/previous processor -- `setup(setup)` / `cleanup()`: Lifecycle management - -**Event Handlers Available**: -- `on_before_process_frame`: Before frame processing -- `on_after_process_frame`: After frame processing -- `on_before_push_frame`: Before pushing to next processor -- `on_after_push_frame`: After pushing to next processor - -**Instrumentation Strategy**: We can hook into the event handlers to create spans around frame processing. - -#### 2. Pipeline (`src/pipecat/pipeline/pipeline.py`) - -**Inheritance**: Compound `FrameProcessor` - -**Key Components**: -- `__init__(processors, *, source, sink)`: Accepts list of processors and links them -- `process_frame(frame, direction)`: Routes frames through source/sink -- `processors_with_metrics`: Returns processors that support metrics -- `_link_processors()`: Connects processors sequentially - -**Instrumentation Strategy**: Pipeline acts as a container; we'll primarily instrument individual processors rather than the pipeline itself. - -#### 3. PipelineTask (`src/pipecat/pipeline/task.py`) - -**Inheritance**: Extends `BasePipelineTask` - -**Key Parameters**: -- `pipeline`: The frame processor pipeline -- `observers`: List of `BaseObserver` instances for monitoring -- `enable_turn_tracking`: Whether to enable turn tracking (default: True) -- `enable_tracing`: Whether to enable tracing (default: False) -- `conversation_id`: Optional conversation identifier - -**Observer Management**: -- `add_observer(observer)`: Add observer at runtime -- `remove_observer(observer)`: Remove observer -- `turn_tracking_observer`: Access to turn tracking instance - -**Event Handlers**: -- `on_pipeline_started`, `on_pipeline_finished`, `on_pipeline_error` -- `on_frame_reached_upstream`, `on_frame_reached_downstream` -- `on_idle_timeout` - -**Instrumentation Strategy**: This is our **primary injection point**. We'll wrap `PipelineTask.__init__` to automatically inject our `OpenInferenceObserver`. - -#### 4. BaseObserver (`src/pipecat/observers/base_observer.py`) - -**Class Definition**: -```python -class BaseObserver(BaseObject): - async def on_process_frame(self, data: FrameProcessed): - """Handle frame being processed by a processor""" - pass - - async def on_push_frame(self, data: FramePushed): - """Handle frame being pushed between processors""" - pass -``` - -**Event Data Classes**: -```python -@dataclass -class FramePushed: - source: FrameProcessor - destination: FrameProcessor - frame: Frame - direction: FrameDirection - timestamp: int -``` - -**Instrumentation Strategy**: We'll create `OpenInferenceObserver(BaseObserver)` to capture all frame flows and create appropriate spans. - -#### 5. Service Base Classes - -##### LLMService (`src/pipecat/services/llm_service.py`) - -**Inheritance**: `LLMService` extends `AIService` - -**Key Methods**: -- `process_frame(frame, direction)`: Handles LLM-related frames -- `run_function_calls()`: Executes function calls from LLM -- `register_function()`, `unregister_function()`: Function call management -- `get_llm_adapter()`: Returns adapter for LLM communication - -**Detection Pattern**: -```python -isinstance(processor, LLMService) -``` - -**Provider Detection**: Check `processor.__class__.__module__`: -- `pipecat.services.openai.llm` → provider: "openai" -- `pipecat.services.anthropic.llm` → provider: "anthropic" -- etc. - -##### TTSService (`src/pipecat/services/tts_service.py`) - -**Inheritance**: `TTSService` extends `AIService` - -**Key Methods**: -- `_process_text_frame(frame)`: Handles incoming text -- `run_tts(text)`: **Abstract method** - subclasses implement text-to-audio conversion -- `_push_tts_frames()`: Applies filters and manages audio output - -**Processing Pipeline**: -1. Receives `TextFrame` or `TTSSpeakFrame` -2. Optional text aggregation (sentence grouping) -3. Text filtering -4. `run_tts()` call → generates audio frames -5. Emits `TTSAudioRawFrame` downstream - -**Detection Pattern**: -```python -isinstance(processor, TTSService) -``` - -##### STTService - -**Pattern**: Similar to TTSService, processes audio → text - -**Detection Pattern**: -```python -isinstance(processor, STTService) -``` - -### Service Provider Architecture - -Pipecat supports **61+ service providers** organized as: -``` -src/pipecat/services/ -├── openai/ # OpenAI LLM, TTS, STT -├── anthropic/ # Claude LLM -├── elevenlabs/ # ElevenLabs TTS -├── deepgram/ # Deepgram STT -├── cartesia/ # Cartesia TTS -└── ... (58 more providers) -``` - -**Provider Detection Strategy**: -```python -def get_provider_from_service(service: FrameProcessor) -> str: - module = service.__class__.__module__ - # e.g., "pipecat.services.openai.llm" → "openai" - parts = module.split('.') - if len(parts) >= 3 and parts[0] == 'pipecat' and parts[1] == 'services': - return parts[2] - return "unknown" -``` - -### Potential Instrumentation Strategies - -#### Option A: Observer-Based Instrumentation (Recommended) -**Advantages:** -- Uses Pipecat's native extension point (`BaseObserver`) -- Non-invasive, works with any service implementation -- Can capture all frame types and pipeline events -- Aligns with LangChain/LlamaIndex patterns (using framework hooks) - -**Implementation:** -- Create `OpenInferenceObserver` extending `BaseObserver` -- Register with `PipelineTask` observers -- Hook into frame events: `on_push_frame` -- Use turn tracking events for conversation-level spans - -#### Option B: Service Wrapper Pattern -**Advantages:** -- More direct control over span lifecycle -- Can wrap specific service methods -- Similar to OpenAI instrumentation pattern - -**Disadvantages:** -- Requires wrapping multiple service base classes -- More invasive, brittle to Pipecat changes -- Doesn't generalize well across providers - -#### Option C: Hybrid Approach (Best of Both Worlds) -**Advantages:** -- Observer for pipeline-level and conversation spans -- Selective wrapping for critical service methods -- Captures both high-level flow and detailed service metrics - -**Implementation:** -- Observer for conversation/turn/pipeline spans -- Wrap `FrameProcessor.process_frame()` for detailed tracing -- Special handling for LLM/TTS/STT service types - -## Recommended Implementation Plan - -## Integration Strategy: No Pipecat Changes Required - -### Key Design Principle: External Observer Pattern - -**All logic stays in the OpenInference package** - we do not need to modify Pipecat itself. This works because: - -1. **BaseObserver is Public API**: Pipecat's `BaseObserver` is designed for external extensions -2. **PipelineTask Accepts Observers**: Tasks can be initialized with custom observers -3. **Dynamic Registration**: `task.add_observer(observer)` works at runtime - -### Implementation Approaches - -#### Approach 1: Automatic Injection (Recommended) - -Wrap `PipelineTask.__init__` to automatically inject our observer: - -```python -# All code in openinference-instrumentation-pipecat package -from pipecat.pipeline.task import PipelineTask -from pipecat.observers.base_observer import BaseObserver - -class OpenInferenceObserver(BaseObserver): - """Our observer - entirely in OpenInference package""" - def __init__(self, tracer: OITracer, config: TraceConfig): - super().__init__() - self._tracer = tracer - self._config = config - self._span_handler = _SpanHandler(tracer) - - async def on_push_frame(self, data: FramePushed): - # Create spans based on frame type and processors - await self._span_handler.handle_frame_push(data) - -class PipecatInstrumentor(BaseInstrumentor): - def _instrument(self, **kwargs): - tracer = OITracer(...) - self._observer = OpenInferenceObserver(tracer=tracer, config=config) - - # Store original __init__ - self._original_task_init = PipelineTask.__init__ - - # Wrap PipelineTask.__init__ to inject our observer - wrap_function_wrapper( - module="pipecat.pipeline.task", - name="PipelineTask.__init__", - wrapper=_TaskInitWrapper(self._observer) - ) - - def _uninstrument(self, **kwargs): - # Restore original - PipelineTask.__init__ = self._original_task_init - self._observer = None - -class _TaskInitWrapper: - def __init__(self, observer: OpenInferenceObserver): - self._observer = observer - - def __call__(self, wrapped, instance, args, kwargs): - # Call original __init__ - wrapped(*args, **kwargs) - - # Inject our observer after initialization - instance.add_observer(self._observer) -``` - -**Advantages:** -- **Completely automatic** - users just call `PipecatInstrumentor().instrument()` -- **No application code changes** - works with existing Pipecat code -- **Clean migration** from manual tracing example -- **Consistent with other instrumentations** (OpenAI, LangChain patterns) - -**Disadvantages:** -- Wraps framework initialization (slightly invasive, but still using public API) -- One shared observer instance across all tasks (may need thread safety) - -#### Approach 2: Manual Observer Registration - -Users explicitly add the observer to their tasks: - -```python -# User's application code -from openinference.instrumentation.pipecat import PipecatInstrumentor, OpenInferenceObserver - -# Instrument (sets up tracer, config) -instrumentor = PipecatInstrumentor() -instrumentor.instrument(tracer_provider=tracer_provider) - -# User creates observer and adds it manually -observer = instrumentor.create_observer() # Factory method -task = PipelineTask(pipeline, observers=[observer]) -``` - -**Advantages:** -- **Simpler implementation** - no monkey-patching needed -- **Explicit control** - users see exactly what's being added -- **Multiple observers** - easy to combine with custom observers -- **Thread-safe** - each task gets its own observer instance - -**Disadvantages:** -- **Requires code changes** - users must modify their applications -- **Less automatic** - not as seamless as other instrumentations -- **Migration friction** - harder to adopt - -#### Recommended: Hybrid Approach - -**Default to automatic injection, but expose observer for manual use:** - -```python -# Automatic (default) - most users -from openinference.instrumentation.pipecat import PipecatInstrumentor - -PipecatInstrumentor().instrument(tracer_provider=provider) -task = PipelineTask(pipeline) # Observer auto-injected ✅ - -# Manual (advanced users) - explicit control -from openinference.instrumentation.pipecat import PipecatInstrumentor, OpenInferenceObserver - -instrumentor = PipecatInstrumentor() -instrumentor.instrument(tracer_provider=provider) - -# Create observer manually for custom configuration or multiple observers -observer = OpenInferenceObserver.create_from_instrumentor(instrumentor) -custom_observer = MyCustomObserver() -task = PipelineTask(pipeline, observers=[observer, custom_observer]) - -# Or disable automatic injection -instrumentor.instrument(tracer_provider=provider, auto_inject=False) -observer = instrumentor.create_observer() -task = PipelineTask(pipeline, observers=[observer]) -``` - -**Benefits of Hybrid Approach:** -- **Automatic by default** - seamless instrumentation for most users -- **Manual override** - advanced users can disable auto-injection -- **Multi-observer support** - combine with custom observers -- **Configuration flexibility** - per-task observer configuration when needed - -### Thread Safety Considerations - -**Challenge**: If we auto-inject a single observer instance, it will be shared across all `PipelineTask` instances. - -**Solutions**: - -1. **Observer Factory Pattern** (Recommended): -```python -class _TaskInitWrapper: - def __init__(self, tracer: OITracer, config: TraceConfig): - self._tracer = tracer - self._config = config - - def __call__(self, wrapped, instance, args, kwargs): - wrapped(*args, **kwargs) - - # Create NEW observer instance for each task - observer = OpenInferenceObserver( - tracer=self._tracer, - config=self._config - ) - instance.add_observer(observer) -``` - -2. **Thread-Safe Shared Observer**: -```python -class OpenInferenceObserver(BaseObserver): - def __init__(self, tracer, config): - self._tracer = tracer - self._config = config - self._task_contexts = {} # task_id -> context - self._lock = asyncio.Lock() - - async def on_push_frame(self, data): - task_id = id(data.source._parent_task) # Get task identifier - async with self._lock: - # Handle per-task state safely - pass -``` - -**Recommendation**: Use **Observer Factory Pattern** to create one observer per task. This is cleaner, safer, and aligns with the principle that each task represents an independent conversation/session. - -### Implementation Summary - -**What gets added to Pipecat**: Nothing ✅ -**What stays in OpenInference package**: Everything ✅ -

self._phase_spans.clear() -``` - -### Phase 3: Service Detection and Attribution - -#### 3.1 Service Type Detection -```python -class _ServiceDetector: - """Detect service types and extract metadata""" - - def detect_service_type(self, processor: FrameProcessor) -> Optional[str]: - # Check inheritance hierarchy - if isinstance(processor, STTService): - return "stt" - elif isinstance(processor, LLMService): -

context_api.detach(token) -``` - -#### 4.2 Integration with Existing Instrumentations - -**Key Insight**: The OpenAI instrumentation (and others) will automatically: -- Detect the active span context -- Create child spans under the current context -- Use proper OpenInference span kinds (LLM for ChatCompletion) - -**Implementation**: -```python -# When LLM service is called, ensure turn span is active -with trace_api.use_span(self._current_turn_span): - # OpenAI service call happens here - # OpenAI instrumentation creates LLM span as child -

-### Phase 6: Testing Strategy - -#### 6.1 Unit Tests -- Test span creation for each frame type -- Verify attribute extraction logic -- Test context propagation -- Validate span hierarchy - -#### 6.2 Integration Tests -- Test with OpenAI services -- Test with alternative providers (ElevenLabs, Cartesia) -- Test turn detection integration -- Test with multiple simultaneous sessions - -#### 6.3 Example Applications -- Basic voice agent (OpenAI only) -- Multi-provider agent (mixed services) -- Text-based pipeline -- Custom processor pipeline - -## Implementation Roadmap - -### Milestone 1: Foundation (Week 1-2) -- [ ] Package structure setup -- [ ] Core `PipecatInstrumentor` class -- [ ] Basic observer implementation -- [ ] Unit test framework -

-### Milestone 6: Production Readiness (Week 11-12) -- [ ] Performance optimization -- [ ] Error handling and recovery -- [ ] Production example with Arize -- [ ] Release preparation - -## Key Design Decisions - -### 1. Observer-Based vs Method Wrapping - -**Decision**: Use observer pattern as primary mechanism -**Rationale**: -- Aligns with Pipecat's design philosophy -- More maintainable and less fragile -- Works across all service providers -- Similar to LangChain/LlamaIndex approach - -### 2. Turn-Based Tracing as Default - -**Decision**: Enable turn-based tracing by default -**Rationale**: -- Most intuitive for conversation applications -- Matches current example implementation -- Can be disabled for streaming/pipeline-only use cases - -### 3. Integration with Existing Instrumentations - -**Decision**: Rely on existing instrumentations (OpenAI, etc.) for service-level spans -**Rationale**: -- Avoid duplicate spans -- Leverage existing attribute extraction logic -- Ensure consistent OpenInference conventions -- Reduce maintenance burden - -### 4. Frame-Level Tracing as Opt-In - -**Decision**: Disable frame-level tracing by default -**Rationale**: -- Can be very verbose (hundreds of frames per turn) -- Most users want conversation-level visibility -- Can be enabled for debugging - -## Migration Path - -### From Manual Tracing to Instrumentation - -**Current Manual Approach:** -```python -# examples/trace/001-trace.py -import tracing_setup -tracing_setup.setup_arize_tracing() -tracing_setup.set_session_id(session_id) -``` - -**New Instrumentation Approach:** -```python -# New approach -from openinference.instrumentation.pipecat import PipecatInstrumentor -from arize.otel import register - -tracer_provider = register(space_id=..., api_key=...) - -instrumentor = PipecatInstrumentor() -instrumentor.instrument(tracer_provider=tracer_provider) - -# That's it! Automatic tracing for all pipelines -``` - -**Benefits:** -- No manual patching required -- Works with any service provider -- Automatic session/turn management -- Configurable span granularity - -## Open Questions for Discussion - -1. **Session Span Creation**: Should session spans be created automatically or require explicit API calls? - - Option A: Automatic based on pipeline lifecycle - - Option B: Explicit `instrumentor.start_session(session_id)` - -2. **Frame Processor Wrapping**: Should we also wrap `FrameProcessor.process_frame()` for fine-grained tracing? - - Pros: More detailed visibility - - Cons: Performance overhead, span explosion - -3. **Service Provider Detection**: How to handle custom services not following naming conventions? - - Option A: Configuration-based service mapping - - Option B: Service registration API - -4. **Backward Compatibility**: Should we maintain the manual tracing API for advanced use cases? - - Option A: Deprecate and migrate - - Option B: Keep as alternative approach - -## Current Implementation Status - -### ✅ COMPLETE - All 69/69 tests passing! - -✅ **Phase 1-3: Core Infrastructure** -- Package structure created -- `PipecatInstrumentor` class implemented -- `OpenInferenceObserver(BaseObserver)` implemented -- Service detection logic working for LLM, TTS, STT -- Span creation for service-level operations (pipecat.llm, pipecat.tts, pipecat.stt) -- Attribute extraction from frames -- Test infrastructure with mocked pipeline execution - -✅ **Phase 4: Turn Tracking - IMPLEMENTED** -- Turn spans created with name `"pipecat.conversation.turn"` -- Turn boundaries detected from frame types (UserStartedSpeaking → BotStoppedSpeaking) -- Turn-level input/output captured from TranscriptionFrame and TextFrame -- Turn interruptions handled (new UserStartedSpeaking during bot speaking) -- Turn numbers tracked incrementally -- Turn end reason captured (completed vs interrupted) - -✅ **Key Implementation Details** -- Observer extends `BaseObserver` (Pipecat's native extension point) -- Automatic injection via wrapping `PipelineTask.__init__` -- One observer instance created per task (factory pattern) -- Service spans finish on `EndFrame` or `ErrorFrame` -- Turn spans finish on `BotStoppedSpeakingFrame` or interruption -- Works with all service providers (OpenAI, Anthropic, ElevenLabs, Deepgram, etc.) - -## Revised Requirements & Implementation Plan - -### Key Requirements (Updated) - -Based on discussion and analysis of Pipecat's extensive frame types (100+ frames across categories like LLM, TTS, STT, audio, control, function calling, etc.), the following requirements have been identified: - -#### 1. **Proper Span Hierarchy & Parent-Child Relationships** - - **Session Level**: All turns within a conversation share a session ID - - **Turn Level**: Root span for each interaction showing overall input/output - - **Service Level**: Child spans for LLM, TTS, STT operations within a turn - - **LLM Specifics**: When LLM is involved, use `OPENINFERENCE_SPAN_KIND = "LLM"` and extract messages - -#### 2. **Session Management** - - Utilize `using_session(session_id)` context manager from openinference-instrumentation - - Session ID propagated via OpenTelemetry context to all child spans - - PipelineTask `conversation_id` parameter maps to session.id attribute - -#### 3. **LLM Frame Handling** - - Detect LLM-related frames: `LLMMessagesFrame`, `LLMMessagesAppendFrame`, `LLMFullResponseStartFrame`, etc. - - Extract messages and use proper OpenInference LLM span kind - - Capture LLM-specific attributes (model, messages, function calls, etc.) - -#### 4. **Generic Frame Handling** - - Don't create unique handlers for every frame type (too many!) - - Capture frame class name as attribute for all frames - - Extract properties based on frame type pattern matching: - - Text content (TextFrame, TranscriptionFrame, etc.) - - Audio metadata (AudioRawFrame variants) - - Control signals (StartFrame, EndFrame, ErrorFrame) - - Function calling (FunctionCallFromLLM, FunctionCallResultFrame) - - Gracefully handle unknown frame types - -#### 5. **Span Hierarchy Example** -``` -Session Span (session.id = "conv-123") - └─> Turn Span 1 (conversation.turn_number = 1, input = "Hello", output = "Hi there!") - ├─> STT Span (service.name = "openai", frame.type = "TranscriptionFrame") - ├─> LLM Span (SPAN_KIND = "LLM", model = "gpt-4", messages = [...]) - │ └─> OpenAI ChatCompletion Span (from openai instrumentation) - └─> TTS Span (service.name = "elevenlabs", voice.id = "...) - └─> Turn Span 2 (conversation.turn_number = 2, ...) - └─> ... -``` - -### Implementation Tasks - -#### ❌ **NOT DONE: Session-Level Span Management** -**Current State**: No session span, turns are not connected -**Required Changes**: -1. Create session span when observer is initialized with `conversation_id` -2. Use `using_session(conversation_id)` to propagate session.id -3. Make all turn spans children of session span via OpenTelemetry context -4. Session span lifecycle: - - Start: When first turn begins OR when observer is created - - End: When pipeline task completes OR explicit session end - -#### ❌ **NOT DONE: Proper Parent-Child Span Relationships** -**Current State**: Spans are created independently, no parent-child links -**Required Changes**: -1. Use `trace_api.use_span()` context manager to set active span -2. Turn spans created within session span context -3. Service spans (LLM, TTS, STT) created within turn span context -4. Verify span hierarchy via `span.parent.span_id` in tests - -#### ❌ **NOT DONE: LLM Span Kind & Message Extraction** -**Current State**: LLM spans use `CHAIN` span kind, don't extract messages -**Required Changes**: -1. Detect LLM service type properly (already done) -2. Change span kind to `OpenInferenceSpanKindValues.LLM` for LLM operations -3. Extract messages from LLM frames: - - `LLMMessagesFrame` → full message list - - `LLMMessagesAppendFrame` → appended messages - - `LLMFullResponseStartFrame` / `LLMFullResponseEndFrame` → response tracking -4. Use `get_llm_input_message_attributes()` and `get_llm_output_message_attributes()` - -#### ✅ **PARTIALLY DONE: Generic Frame Attribute Extraction** -**Current State**: Basic frame attributes extracted (text, some metadata) -**Required Enhancements**: -1. Always capture `frame.type` = frame.__class__.__name__ -2. Pattern-based extraction: - ```python - # Text frames - if hasattr(frame, 'text') and frame.text: - yield SpanAttributes.INPUT_VALUE or OUTPUT_VALUE, frame.text - - # Audio frames - if hasattr(frame, 'audio') and hasattr(frame, 'sample_rate'): - yield "audio.sample_rate", frame.sample_rate - - # Function calling - if isinstance(frame, FunctionCallFromLLM): - yield "tool.name", frame.function_name - yield "tool.arguments", frame.arguments - ``` -3. Error handling for unknown frames (just log frame type, don't fail) - -## Turn Tracking Implementation Plan - -### Problem Statement - -Turn tracking tests expect: -1. Spans with name `"pipecat.conversation.turn"` -2. Attributes: - - `conversation.turn_number` (incremental counter) - - `INPUT_VALUE` (user transcription text) - - `OUTPUT_VALUE` (bot response text) - - `conversation.end_reason` (completed/interrupted) - -3. Turn boundaries defined by frames: - - **Turn Start**: `UserStartedSpeakingFrame` - - **User Input**: `TranscriptionFrame` (contains user text) - - **User Stop**: `UserStoppedSpeakingFrame` - - **Bot Start**: `BotStartedSpeakingFrame` - - **Bot Output**: `TextFrame` (contains bot response text) - - **Turn End**: `BotStoppedSpeakingFrame` - - **Interruption**: New `UserStartedSpeakingFrame` before `BotStoppedSpeakingFrame` - -### Implementation Approach - -**Enhance OpenInferenceObserver to track turn state:** - -```python -class OpenInferenceObserver(BaseObserver): - def __init__(self, tracer: OITracer, config: TraceConfig): - super().__init__() - self._tracer = tracer - self._config = config - - # Existing service span tracking - self._detector = _ServiceDetector() - self._attribute_extractor = _FrameAttributeExtractor() - self._active_spans = {} # service spans - self._last_frames = {} - - # NEW: Turn tracking state - self._turn_state = { - 'active': False, - 'span': None, - 'turn_number': 0, - 'user_text': [], - 'bot_text': [], - 'started_at': None, - } -``` - -### Turn Tracking Logic - -**Detect turn boundary frames in `on_push_frame()`:** - -```python -async def on_push_frame(self, data: FramePushed): - from pipecat.frames.frames import ( - UserStartedSpeakingFrame, - UserStoppedSpeakingFrame, - BotStartedSpeakingFrame, - BotStoppedSpeakingFrame, - TranscriptionFrame, - TextFrame, - EndFrame, - ErrorFrame, - ) - - frame = data.frame - - # Turn tracking logic (NEW) - if isinstance(frame, UserStartedSpeakingFrame): - await self._start_turn() - elif isinstance(frame, TranscriptionFrame): - if self._turn_state['active'] and frame.text: - self._turn_state['user_text'].append(frame.text) - elif isinstance(frame, UserStoppedSpeakingFrame): - pass # User finished speaking, wait for bot - elif isinstance(frame, BotStartedSpeakingFrame): - pass # Bot starting response - elif isinstance(frame, TextFrame): - if self._turn_state['active'] and frame.text: - self._turn_state['bot_text'].append(frame.text) - elif isinstance(frame, BotStoppedSpeakingFrame): - await self._finish_turn(interrupted=False) - - # Existing service span logic (unchanged) - service_type = self._detector.detect_service_type(data.source) - if service_type: - await self._handle_service_frame(data, service_type) -``` - -### Turn Span Creation - -```python -async def _start_turn(self): - """Start a new conversation turn.""" - # If there's an active turn, it was interrupted - if self._turn_state['span']: - await self._finish_turn(interrupted=True) - - # Increment turn counter - self._turn_state['turn_number'] += 1 - self._turn_state['active'] = True - self._turn_state['user_text'] = [] - self._turn_state['bot_text'] = [] - - # Create turn span - span = self._tracer.start_span( - name="pipecat.conversation.turn", - attributes={ - "conversation.turn_number": self._turn_state['turn_number'], - SpanAttributes.OPENINFERENCE_SPAN_KIND: OpenInferenceSpanKindValues.CHAIN.value, - } - ) - self._turn_state['span'] = span - - logger.debug(f"Started turn {self._turn_state['turn_number']}") - -async def _finish_turn(self, interrupted: bool = False): - """Finish the current conversation turn.""" - if not self._turn_state['active'] or not self._turn_state['span']: - return - - span = self._turn_state['span'] - - # Add input text (user transcription) -

self._turn_state['active'] = False - self._turn_state['span'] = None -``` - -### Implementation Steps - -1. **Add turn state to OpenInferenceObserver.__init__()** - - Initialize turn tracking dictionary - -2. **Add turn frame detection to on_push_frame()** - - Check for UserStartedSpeaking, BotStoppedSpeaking, etc. - - Collect TranscriptionFrame and TextFrame content - -3. **Implement _start_turn() method** - - Create turn span with turn_number attribute - - Handle interruptions (previous turn still active) - -4. **Implement _finish_turn() method** - - Add INPUT_VALUE and OUTPUT_VALUE from collected text - - Add conversation.end_reason attribute - - End the span - -5. **Test with turn tracking tests** - - `test_complete_turn_cycle` - basic turn - - `test_multiple_sequential_turns` - multiple turns - - `test_turn_interruption` - interruption handling - -### Success Criteria - -- ✅ All 69 tests pass (currently 66/69) -- ✅ Turn spans created with name "pipecat.conversation.turn" -- ✅ Turn spans have `conversation.turn_number` attribute -- ✅ Turn spans capture `INPUT_VALUE` and `OUTPUT_VALUE` -- ✅ Interruptions set `conversation.end_reason` = "interrupted" -- ✅ Completed turns set `conversation.end_reason` = "completed" - -### Design Rationale - -**Why enhance OpenInferenceObserver vs integrate with TurnTrackingObserver?** - -1. **Works with mocked tests**: Our test infrastructure mocks PipelineRunner execution, which doesn't trigger Pipecat's TurnTrackingObserver properly -2. **Full control**: We control the exact OpenTelemetry span attributes -3. **Simpler**: Single observer handles all tracing (services + turns) -4. **Maintainable**: All tracing logic in one place -5. **Future-proof**: Can migrate to integrate with TurnTrackingObserver later if needed - -**Note**: For real applications using PipelineRunner, Pipecat's native TurnTrackingObserver also runs. Our observer creates OpenTelemetry spans; theirs creates Pipecat events. They coexist independently. - -## CRITICAL ISSUE: Turn Tracking Strategy Needs Redesign - -### Current Problem Analysis (2025-10-29) - -**Issue**: The current turn tracking implementation creates **excessive orphaned turn spans** due to frame propagation through the pipeline. - -**Root Cause**: `BotStoppedSpeakingFrame` propagates through **every processor in the pipeline**. When we react to this frame without filtering by source, we: -1. Finish turn at first processor (e.g., SmallWebRTCOutputTransport) -2. Start new turn immediately -3. Frame continues to next processor (LLMAssistantAggregator) -4. `BotStoppedSpeakingFrame` triggers finish → **new turn created again** -5. Repeats for every processor in the chain - -**Evidence from Logs**: -``` -Line 1958: FINISHING TURN #1 (SmallWebRTCOutputTransport) -Line 1979: STARTING TURN #2 (LLMAssistantAggregator receives BotStoppedSpeaking) -Line 1995: FINISHING TURN #2 (0.001ms duration - empty!) -Line 2004: STARTING TURN #3 (OpenAILLMService receives BotStoppedSpeaking) -Line 2022: FINISHING TURN #3 (0.001ms duration - empty!) -...continues for 5+ processors -``` - -**Result**: In a conversation with 2 actual exchanges, we get **18 turn spans**, most empty (< 1ms duration). - -### Proposed Solution: Transport-Layer-Only Turn Tracking - -**Strategy**: Only react to speaking frames from **transport layer sources** to avoid duplicate turn creation from frame propagation. - -**Key Changes**: - -1. **Filter Speaking Frames by Source**: -```python -# In on_push_frame() -source_name = data.source.__class__.__name__ if data.source else "Unknown" -is_transport = "Transport" in source_name - -# Only track turns from transport layer -if isinstance(frame, UserStartedSpeakingFrame) and is_transport: - # Start turn -if isinstance(frame, BotStoppedSpeakingFrame) and is_transport: - # End turn -``` - -2. **Transport Sources to Track**: -- `SmallWebRTCInputTransport` - User input -- `SmallWebRTCOutputTransport` - Bot output -- Other transport implementations (DailyTransport, etc.) - -**Benefits**: -- Only 1 turn span per actual conversation exchange -- Turns represent actual user ↔ bot interactions -- Service spans (STT, LLM, TTS) properly nested under turn -- Cleaner traces with meaningful turn boundaries - -### Alternative Considered: Conversation Exchange Model - -Instead of "turns", track **conversation exchanges** as complete request/response cycles: - -**Approach**: -- **Start Exchange**: When LLM service receives input (first service activity) -- **End Exchange**: When TTS completes output (last service activity) -- **Each exchange contains**: STT → LLM → TTS pipeline - -**Pros**: -- Aligns with actual processing flow -- Guarantees complete service span capture -- Less dependent on speaking frame propagation - -**Cons**: -- Doesn't match user's mental model of "turns" -- Harder to detect exchange boundaries -- May miss initialization activity - -**Decision**: Proceed with transport-layer filtering approach as it's simpler and aligns with existing turn concept. - -### Alternative Considered: Turn Detection via Service Activity - -**Approach**: -- **Start turn**: When first service (STT, LLM, or TTS) receives a frame -- **End turn**: When last service (typically TTS) finishes -- Ignore speaking frames entirely - -**Pros**: -- Guaranteed to capture all service activity -- No duplicate turns from frame propagation -- Works regardless of speaking frame behavior - -**Cons**: -- May not align with user expectations of "turn" boundaries -- Harder to detect interruptions -- Initialization spans might get orphaned - -### Implementation Plan - -1. **Add source filtering to speaking frame handlers** ([_observer.py:139-166](src/openinference/instrumentation/pipecat/_observer.py#L139-L166)) -2. **Test with real conversation** to verify only transport-layer turns are created -3. **Verify service spans are properly nested** under turn spans -4. **Check for any orphaned initialization spans** - -### Success Criteria - -- ✅ 2 actual exchanges = 2 turn spans (not 18!) -- ✅ Turn spans have meaningful duration (> 1 second, not 0.001ms) -- ✅ Turn spans contain input/output text -- ✅ Service spans (STT, LLM, TTS) are children of turn spans -- ✅ No orphaned service spans with different trace_ids - -## Prioritized Next Steps - -### 🔴 **HIGHEST PRIORITY: Fix Turn Tracking to Eliminate Orphaned Spans** - -**Problem**: Current implementation creates 18+ turn spans for 2 actual exchanges due to frame propagation through pipeline. - -**Tasks**: - -1. **Implement Transport-Layer Filtering** ([_observer.py:139-166](src/openinference/instrumentation/pipecat/_observer.py#L139-L166)): - - Add `is_transport = "Transport" in source_name` check - - Only react to `UserStartedSpeakingFrame` when `is_transport == True` - - Only react to `BotStartedSpeakingFrame` when `is_transport == True` - - Only react to `BotStoppedSpeakingFrame` when `is_transport == True` - - This prevents duplicate turn creation from frames propagating through pipeline - -2. **Fix Service Span Context Propagation** ([_observer.py:195-215](src/openinference/instrumentation/pipecat/_observer.py#L195-L215)): - - Current: Service spans created with `context=self._turn_context_token` (WORKS!) - - Keep this approach - it's correct and creates proper parent-child relationships - - Issue is NOT context propagation, it's turn span creation timing - -3. **Session ID Attribution** ([__init__.py:119](src/openinference/instrumentation/pipecat/__init__.py#L119)): - - ✅ **FIXED**: Now extracts `_conversation_id` from PipelineTask correctly - - ✅ **WORKING**: session.id attribute appears on turn spans - - Need to verify session.id also appears on service spans (should inherit from turn context) - -4. **Test with Real Conversation**: - - Run conversation example with transport filtering - - Verify: 2 exchanges = 2 turn spans (not 18) - - Verify: Service spans have correct parent_id pointing to turn span - - Verify: All spans share same trace_id within a turn - - Verify: session.id attribute appears on all spans - -**Current Implementation Status**: -```python -# CURRENT CODE (working for service spans, broken for turns) -async def _handle_service_frame(self, data: FramePushed, service_type: str): - if service_id not in self._active_spans: - # Auto-start turn if none exists - if self._turn_context_token is None: - self._turn_context_token = await self._start_turn() - - # Create service span WITH turn context (THIS WORKS!) - span = self._create_service_span(service, service_type) - # span.parent will be turn_span ✅ - -# BROKEN CODE (creates too many turns) -async def on_push_frame(self, data: FramePushed): - # Problem: Reacts to BotStoppedSpeakingFrame from EVERY processor -

is_transport = "Transport" in source_name - - # Only react to transport layer - if isinstance(frame, BotStoppedSpeakingFrame) and is_transport: - await self._finish_turn(interrupted=False) -``` - -### 🟡 **MEDIUM PRIORITY: LLM Span Kind & Message Extraction** - -**Problem**: LLM spans currently use `CHAIN` span kind instead of `LLM`, and don't extract message content. - -**Tasks**: -1. **Detect LLM Frames** ([_attributes.py](src/openinference/instrumentation/pipecat/_attributes.py)): - - Add detection for `LLMMessagesFrame`, `LLMMessagesAppendFrame`, `LLMFullResponseStartFrame` - - Extract message content from frames - -2. **Change Span Kind** ([_observer.py](src/openinference/instrumentation/pipecat/_observer.py)): - - When service_type == "llm", use `OpenInferenceSpanKindValues.LLM` - - Extract and set LLM message attributes using `get_llm_input_message_attributes()` - -3. **Test LLM Spans** (new test file): - - Verify LLM span kind is correct - - Verify messages are extracted - - Verify integration with OpenAI instrumentation (nested spans) - -### 🟢 **LOW PRIORITY: Enhanced Frame Attribute Extraction** - -**Problem**: Not all frame types have their properties extracted. Need generic handler. - -**Tasks**: -1. **Add frame.type Attribute** ([_attributes.py](src/openinference/instrumentation/pipecat/_attributes.py)): - - Always set `frame.type = frame.__class__.__name__` - -2. **Pattern-Based Extraction** ([_attributes.py](src/openinference/instrumentation/pipecat/_attributes.py)): - - Check for common properties: `text`, `audio`, `sample_rate`, `function_name`, etc. - - Use hasattr() to gracefully handle missing properties - - Log unknown frame types for debugging - -3. **Function Calling Support** ([_attributes.py](src/openinference/instrumentation/pipecat/_attributes.py)): - - Detect `FunctionCallFromLLM`, `FunctionCallResultFrame` - - Extract tool.name, tool.arguments, tool.output - -### Testing & Validation - -After implementing each priority: -1. Run full test suite: `pytest tests/` -2. Verify span hierarchy in actual example -3. Check Phoenix/Arize UI for proper trace structure - -## Acceptance Criteria - -The implementation will be considered complete when: - -1. ✅ All 69 tests pass -2. ✅ Session ID propagates to all spans in a conversation -3. ✅ Turn spans are children of session context -4. ✅ Service spans (LLM, TTS, STT) are children of turn spans -5. ✅ LLM spans use `SPAN_KIND = "LLM"` and extract messages -6. ✅ Frame types are captured for all frames -7. ✅ Example trace shows proper hierarchy in Phoenix/Arize - -## References - -- [OpenInference Semantic Conventions](https://github.com/Arize-ai/openinference/tree/main/spec) -- [OpenTelemetry Instrumentation Guide](https://opentelemetry.io/docs/instrumentation/python/) -- [Pipecat Documentation](https://docs.pipecat.ai/) -- [Pipecat Frame Types](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/frames/frames.py) -- Current Example: [examples/trace/tracing_setup.py](examples/trace/tracing_setup.py) diff --git a/python/instrumentation/openinference-instrumentation-pipecat/examples/requirements.txt b/python/instrumentation/openinference-instrumentation-pipecat/examples/requirements.txt deleted file mode 100644 index 86648dba68..0000000000 --- a/python/instrumentation/openinference-instrumentation-pipecat/examples/requirements.txt +++ /dev/null @@ -1,10 +0,0 @@ -# Core dependencies -pipecat-ai -openai>=1.0.0 -grpcio>=1.60.0 -arize-otel -dotenv - -# OpenTelemetry and Observability -opentelemetry-sdk>=1.22.0 -opentelemetry-exporter-otlp-proto-grpc>=1.22.0 diff --git a/python/instrumentation/openinference-instrumentation-pipecat/examples/trace/README.md b/python/instrumentation/openinference-instrumentation-pipecat/examples/trace/README.md deleted file mode 100644 index 40bbd4779a..0000000000 --- a/python/instrumentation/openinference-instrumentation-pipecat/examples/trace/README.md +++ /dev/null @@ -1,11 +0,0 @@ -```bash -uv sync -uv pip install -e '.[cartesia,daily,elevenlabs,local-smart-turn-v3,openai,runner,webrtc]' -``` - -```bash -python examples/foundational/trace/001-trace.py -``` - -- open [http://localhost:7860](http://localhost:7860) -- click `connect` button in top right \ No newline at end of file From 25ef3dfd19b139c4e16c710ab8a019c12d7f0c8f Mon Sep 17 00:00:00 2001 From: Duncan McKinnon <13010582+duncankmckinnon@users.noreply.github.com> Date: Thu, 6 Nov 2025 12:23:30 -0800 Subject: [PATCH 30/44] using built-in safe_json_dumps --- .gitignore | 3 +++ .../instrumentation/pipecat/_attributes.py | 22 ++----------------- 2 files changed, 5 insertions(+), 20 deletions(-) diff --git a/.gitignore b/.gitignore index 5af82ed8f4..80abbcbf56 100644 --- a/.gitignore +++ b/.gitignore @@ -109,3 +109,6 @@ Thumbs.db # Scratch files .scratch/ + +# Workspace Definitions +*.code-workspace \ No newline at end of file diff --git a/python/instrumentation/openinference-instrumentation-pipecat/src/openinference/instrumentation/pipecat/_attributes.py b/python/instrumentation/openinference-instrumentation-pipecat/src/openinference/instrumentation/pipecat/_attributes.py index 5a8a0e8806..3df7a4b35a 100644 --- a/python/instrumentation/openinference-instrumentation-pipecat/src/openinference/instrumentation/pipecat/_attributes.py +++ b/python/instrumentation/openinference-instrumentation-pipecat/src/openinference/instrumentation/pipecat/_attributes.py @@ -1,10 +1,10 @@ """Attribute extraction from Pipecat frames.""" import base64 -import json import logging -from typing import Any, Callable, Dict, List, Optional +from typing import Any, Callable, Dict, List +from openinference.instrumentation.helpers import safe_json_dumps from openinference.semconv.trace import OpenInferenceSpanKindValues, SpanAttributes from pipecat.frames.frames import ( AudioRawFrame, @@ -50,24 +50,6 @@ ] -def safe_json_dumps(obj: Any, default: Optional[str] = None) -> Optional[str]: - """ - Safely serialize an object to JSON, returning None if serialization fails. - - Args: - obj: The object to serialize - default: Default value to return on error (defaults to None) - - Returns: - JSON string or default value on error - """ - try: - return json.dumps(obj) - except Exception as e: - logger.debug(f"Failed to serialize object to JSON: {e}") - return default - - def safe_extract(extractor: Callable[[], Any], default: Any = None) -> Any: """ Safely execute an extractor function, returning default value on error.

New GenAI convention attributes are added alongside. - -### New Attributes Available - -After upgrading, traces will include: - -**GenAI Semantic Conventions:** -- `gen_ai.request.model` -- `gen_ai.system` -- `gen_ai.operation.name` - -**Enhanced Metrics:** -- `metrics.ttfb` - Time to first byte -- `metrics.character_count` - TTS character count -- `is_final` - Transcription finality status -- `vad_enabled` - Voice activity detection status - -**Enhanced Tool Tracking:** -- `tools.count` - Number of tools available -- `tools.names` - Array of tool names -- `tools.definitions` - Full tool definitions (if < 10KB) - -### Querying Traces - -Both conventions can be queried: - -```python -# OpenInference convention (existing) -traces.filter(lambda t: t.attributes.get("llm.model_name") == "gpt-4") - -# GenAI convention (new) -traces.filter(lambda t: t.attributes.get("gen_ai.request.model") == "gpt-4") -``` - ---- - -## Benefits Summary - -### For Users - -1. **Better observability** - TTFB, character counts, VAD status -2. **Nested call visibility** - See LLM calls inside TTS/STT services with full prompts and responses -3. **Standard compliance** - GenAI semantic conventions alignment -4. **Enhanced tool tracking** - See all tool definitions -5. **Backward compatible** - No breaking changes -6. **Ecosystem compatibility** - Works with Pipecat's native tracing -7. **Cost tracking** - Track LLM usage even when embedded in other services -8. **Performance debugging** - Identify slow nested LLM calls affecting TTS/STT latency - -### For the Project - -1. **Alignment with Pipecat** - Follows official patterns -2. **Future-proof** - GenAI conventions are industry standard -3. **Richer telemetry** - More actionable data -4. **Better debugging** - TTFB and streaming metrics -5. **Complete visibility** - No hidden service calls -6. **Accurate span hierarchy** - Proper parent-child relationships - -### Key Use Cases Enabled - -#### 1. TTS with LLM-based Voice Modulation -``` -User speaks → STT → LLM (main) → TTS (with nested LLM for prosody) → Audio output -``` -**Before:** Only see TTS span, miss the LLM call for voice modulation -**After:** See complete chain including nested LLM with its prompt/response - -#### 2. STT with LLM Post-Processing -``` -Audio input → STT (with nested LLM for punctuation) → Formatted text -``` -**Before:** Only see STT span with final output -**After:** See both raw STT output AND the LLM refinement step - -#### 3. Cost Attribution -Track token usage from LLMs even when they're called internally by TTS/STT: -- See which services use nested LLMs -- Track token costs per service type -- Identify opportunities to cache or optimize nested calls - ---- - -## Open Questions - -1. **Should we deprecate old attribute names?** - - Recommendation: No, maintain both for compatibility - -2. **How to handle attribute size limits?** - - Recommendation: 10KB limit for tool definitions, truncate with warning - -3. **Should we support decorator-based instrumentation?** - - Recommendation: Not initially, observer pattern is sufficient - -4. **GenAI token usage attributes?** - - Recommendation: Add `gen_ai.usage.input_tokens`, `gen_ai.usage.output_tokens` mapping -
