Lorenze/feat/oss warf stamp execution - #6996
Conversation
Open spans directly on the user's thread so that stdlib log records emitted during hot paths like `Crew.kickoff`, `BaseTool.run`, and `LLM.call` carry the active trace context and correlate with the spans they belong to — a gap the previous metrics-only telemetry could not close. Introduces a `crewai.telemetry.otel` module exposing `operation` and `follows_from`, instruments the execution hot paths, and propagates the active context across every parallel-dispatch site. Depends only on `opentelemetry-api` so provider and exporter choice stays with the host application per the standard OTel library pattern; without an installed SDK the `ProxyTracer` keeps everything as a NoOp. Co-authored-by: Cursor <cursoragent@cursor.com>
Address review feedback on the native OpenTelemetry instrumentation
`test_otel.py`'s `span_exporter` fixture installed an SDK `TracerProvider` once via module-level globals and never restored the default `ProxyTracerProvider`, so `test_otel_noop.py`'s unconfigured- default-state assertions failed whenever the two files ran on the same worker. Install the SDK provider fresh per test and reset the global slot back to `ProxyTracerProvider` in `finally`; `_tracer()` re-resolves on every span so swapping providers between tests is safe.
`Telemetry.set_tracer()` installed crewAI's anonymous SDK
`TracerProvider` into OpenTelemetry's process-global slot, so the first
`Crew` constructed in a test or host application replaced the default
`ProxyTracerProvider` and exfiltrated every host span emitted via
`trace.get_tracer(...)` to crewAI's OTLP endpoint. Keep the provider
local to the `Telemetry` instance and route every anonymous span
through `self.provider.get_tracer("crewai.telemetry")` so the global
slot stays untouched. Mirrors the fix in `crewai_core.telemetry`,
drops the now-dead `set_tracer()` calls in `event_listener.py` and
`crewai_cli.command`, and adds regression coverage that asserts the
provider stays a `ProxyTracerProvider` after constructing a `Crew`.
Enhance the `operation` function to include the execution UUID in span attributes, allowing for better tracking of execution contexts. If an execution UUID is present, it is added to the span attributes unless explicitly provided. Additionally, introduce tests to verify that the execution UUID is correctly stamped from the context and that explicit UUIDs are preserved. This improves traceability in telemetry data.
📝 WalkthroughWalkthroughThe PR adds OpenTelemetry operation spans to core CrewAI execution, LLM, memory, knowledge, tool, flow, guardrail, and A2A paths. It also propagates telemetry context across asynchronous event handlers and executor threads, with comprehensive SDK and no-provider tests. ChangesOpenTelemetry instrumentation

Merge Risk: 🟠 High · up to This PR adds broad execution telemetry, but the current implementation can export credentials or query tokens embedded in A2A endpoint URLs to telemetry backends, while some converted tool calls and bulk memory writes can bypass expected instrumentation.

Tool spans miss agent path
Medium Severity
operation("call tool") was added on BaseTool.run/arun, but agent execution goes through CrewStructuredTool.invoke/ainvoke via tool_usage, which call func (_run) directly and never enter those wrappers. Normal crew tool calls therefore emit no call tool spans, so the hot-path tool nesting this PR aims to stamp is missing in production.

Sanitize endpoint before recording it as a span attribute.
endpoint is a caller-supplied A2A URL. It can carry credentials in the userinfo component or a token in the query string, for example https://user:token@host/a2a?api_key=.... Span attributes are exported to the configured OpenTelemetry backend, so the raw URL becomes a new sink for secrets. Record only the scheme, host, and path.

parts = urlsplit(endpoint)

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Instrument the non-blocking memory save path.
remember_many() submits _background_encode_batch() without a "remember memory" operation. Therefore, remember_many() and aremember_many() do not emit the save span that remember() emits.
Wrap the background save workflow in the same operation. Add a behavior test that calls remember_many(), drains writes, and asserts the span name and source-type attribute.
As per coding guidelines, "**/*test*.py: Write unit tests for new functionality, focusing on behavior rather than implementation details."

🌐 Web query:
opentelemetry-api 1.42.0 SpanContext constructor parameters trace_flags Link attributes
💡 Result:
In the OpenTelemetry API 1.42.0, the SpanContext class is immutable and is typically created using factory methods rather than public constructors [1][2][3]. Specifically, the SpanContext is created using static factory methods such as create(String, String, TraceFlags, TraceState) and createFromRemoteParent(String, String, TraceFlags, TraceState) [1]. Regarding your query on parameters and structure: SpanContext Parameters The factory methods for SpanContext accept the following parameters: - traceIdHex: The trace identifier as a hex string [1]. - spanIdHex: The span identifier as a hex string [1]. - traceFlags: An instance of TraceFlags, which contains trace-specific flags (e.g., whether the span is sampled) [1][2][4]. - traceState: An instance of TraceState, which stores system-specific information [1][2][3]. Link Structure A Link is a distinct entity from a SpanContext [2][4]. While a SpanContext represents the portion of a Span that is propagated, a Link is used to relate a Span to another Span [2][4]. A Link is structurally defined by: - SpanContext: The context of the Span to link to [4][5][6]. - Attributes: A collection of zero or more attributes that further describe the link [4][5][6]. Note that while a Link contains a SpanContext (and thus implicitly includes the TraceFlags contained within that context), the Link structure itself does not independently redefine or manage TraceFlags; it primarily serves to associate a SpanContext with optional metadata (attributes) [4][7].

opentelemetry-python 1.42.0 opentelemetry.trace SpanContext __init__ Link __init__ attributes
💡 Result:
In opentelemetry-python 1.42.0, SpanContext and Link are core components of the tracing API [1][2]. SpanContext The SpanContext class is an immutable, serializable representation of a span's state [2][3]. It is implemented as a tuple that holds the data necessary for propagating trace information across process boundaries [3][4]. Its constructor (new) accepts the following parameters [3][5]: trace_id (int): The ID of the trace to which the span belongs [3]. span_id (int): The ID of the span itself [3]. is_remote (bool): True if the span context was propagated from a remote parent [3]. trace_flags (TraceFlags, optional): Tracing options (defaults to DEFAULT_TRACE_OPTIONS) [3][5]. trace_state (TraceState, optional): Tracing-system-specific information (defaults to DEFAULT_TRACE_STATE) [3][5]. Internally, SpanContext validates the provided trace_id and span_id to ensure they are within valid ranges [3][4]. Because it is immutable, attempts to modify its attributes are ignored [4]. Link The Link class represents a reference to another span [1][6]. Its attributes are immutable [1][6]. The Link.init method is defined as follows [1][7]: def init(self, context: "SpanContext", attributes: types.Attributes = None) -> None: super.init(context) self._attributes = attributes Parameters: context (SpanContext): The SpanContext of the span to link to [1][8]. attributes (types.Attributes, optional): A mapping of key-value pairs further describing the link [1][8]. The attributes of a Link can be accessed via the.attributes property [1][6]. Additionally, if the provided attributes are an instance of BoundedAttributes, the Link class provides a dropped_attributes property to report how many attributes were dropped due to limits [1][7]. Links are typically added during span creation via the Tracer.start_span or start_as_current_span methods, which accept a list of links [1][2].

Validate untrusted trace and span IDs.
SpanContext and Link accept the shown keyword arguments in OpenTelemetry 1.42.x. Invalid IDs mark SpanContext invalid without raising. Because this link has attributes, the SDK still accepts it. If callers can provide unvalidated IDs, reject IDs outside the valid ranges before constructing the link.

Instrument converted structured-tool execution.
BaseTool.to_structured_tool() assigns self._run to CrewStructuredTool.func. CrewStructuredTool.ainvoke() invokes that callable directly. This bypasses all four new "call tool" wrappers.
Add the operation at the CrewStructuredTool invocation boundary, or route converted tools through an equivalent instrumented boundary. Add a behavior test that invokes a converted tool and asserts one "call tool" span. Preserve the original ToolExecutionFailedError object if that path raises it.
As per coding guidelines, "**/*test*.py: Write unit tests for new functionality, focusing on behavior rather than implementation details." Based on learnings, "ToolExecutionFailedError ... must be re-raised unchanged at every tool-execution boundary."

opentelemetry-api 1.42.0 trace _TRACER_PROVIDER_SET_ONCE Once _done attribute
💡 Result:
The symbol _TRACER_PROVIDER_SET_ONCE is an internal mechanism specifically found in the OpenTelemetry Python API [1][2]. It is used to enforce the singleton pattern for the global TracerProvider, ensuring that the provider is set only once during the application's lifecycle [1][2]. When set_tracer_provider() is called, it utilizes _TRACER_PROVIDER_SET_ONCE (which is an instance of a Once utility class) to execute the registration logic [1][2]. If a subsequent attempt is made to set the TracerProvider, the Once mechanism prevents the override and a warning, "Overriding of current TracerProvider is not allowed," is logged [1][2][3]. This behavior is intentional to maintain stability and prevent inconsistent tracing configuration throughout an application [3]. It is important to note that this is a detail of the OpenTelemetry Python implementation [1][2]. While OpenTelemetry Java also enforces singleton-like behavior for global providers, it uses different architectural patterns (such as OpenTelemetrySdkBuilder and SPI-based configuration) rather than this specific internal attribute name [4][5][6][7].

site:github.com/open-telemetry/opentelemetry-python v1.42.0 opentelemetry-api trace "__TRACER_PROVIDER_SET_ONCE" "_done"
💡 Result:
In the OpenTelemetry Python API (opentelemetry-api), specifically as observed in version 1.42.0, the _TRACER_PROVIDER_SET_ONCE variable is an instance of a utility class (typically Once) used to ensure that the global TracerProvider is configured only once [1][2]. The _done attribute or method is not a standalone identifier you would interact with directly; rather, it is part of the internal implementation logic used to manage state [1][3]. Specifically, _TRACER_PROVIDER_SET_ONCE.do_once(set_tp) executes the provided function (set_tp) only the first time it is called [1][4]. This pattern prevents the global TracerProvider from being overridden after it has been initialized [1][5]. Key details regarding this mechanism include: - Purpose: It enforces that the global TracerProvider is set exactly once during the lifecycle of an application to prevent tracing configuration conflicts [1][5]. - Behavior: If an attempt is made to call set_tracer_provider() a second time, the system ignores the new provider and logs a warning stating that overriding the current TracerProvider is not allowed [1][4]. - Implementation: The _set_tracer_provider function uses this Once instance to perform a thread-safe update of the global _TRACER_PROVIDER variable [1][4]. If you are encountering this in a stack trace or debugging output, it confirms that the OpenTelemetry global tracer provider has already been initialized, and any subsequent attempts to modify it are being rejected by design [1][5]. To avoid this, ensure that your application calls set_tracer_provider only once during the application's startup phase, before any tracers are created [6].

OpenTelemetry Python v1.42.0 opentelemetry-api util _once.py class Once _done
💡 Result:
In OpenTelemetry Python v1.42.0, the Once class is defined within the opentelemetry-api package at opentelemetry/util/_once.py [1]. The Once class is designed to execute a provided function exactly once, blocking all other callers until the execution is complete [1]. It behaves similarly to the sync.Once primitive in Go [1]. Key implementation details of the Once class include: - The _done attribute: This boolean flag tracks whether the function has already been executed [1]. It is initialized to False in the constructor [1]. - The do_once method: This method takes a callable (the function to execute) as an argument [1]. It uses a thread lock to ensure thread safety [1]. - Execution logic: - It first checks the _done flag without locking (a "fast path") to avoid unnecessary locking if the operation has already occurred [1]. - If _done is False, it acquires a threading.Lock, re-checks the _done flag (to prevent race conditions), executes the function, sets _done to True, and releases the lock [1]. - The method returns a boolean indicating whether the function was executed during that specific call [1]. This utility is used internally within the OpenTelemetry Python ecosystem to manage initialization tasks safely [2], and external projects may also utilize it to ensure thread-safe, single-execution initialization [3]. In v1.42.0, the file was updated primarily for tasks such as updating license headers, though the core logic of the Once class remains consistent with its purpose [4][5].

Note
Medium Risk
Touches hot execution paths (crew kickoff, agents, event bus, tools) with mostly observability wrappers, but incorrect context propagation or span error handling could affect tracing fidelity or edge cases like HITL pauses.
Overview
Adds native OpenTelemetry instrumentation via a new
crewai.telemetry.otelmodule (operation,follows_from) and wraps major runtime work in named spans withcrewai.*attributes and optionalcrewai.execution_uuidstamping.Instrumented paths include crew/flow kickoff and resume, tasks, agents (task + kickoff), LLM calls (core + provider completions), tools, knowledge queries, unified memory remember/recall, A2A delegation, agent reasoning, and LLM guardrails. Flow changes also treat
HumanFeedbackPendingas non-error spans and keep coroutine auto-await inside the flow-method span.Trace continuity fixes: the event bus re-attaches OTel context when dispatching async handlers via
run_coroutine_threadsafe, and structured tools run sync funcs in a thread pool withcontextvars.copy_context()so spans don’t break at thread boundaries.Tests cover span nesting, log correlation, noop behavior without an SDK provider, and propagation patterns for audited thread-pool sites.
