feat(tracing): export execution spans directly to Wharf#7359lorenzejay wants to merge 13 commits into
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.

Refactor the execution context handling in the `Crew` and `Agent` classes to improve traceability and error management. The `begin_execution` function now accepts optional tracing parameters, allowing for better integration with telemetry. Additionally, error handling has been refined to raise `TraceGrantError` when execution tokens are not set, ensuring that trace-related issues are properly surfaced. This update also introduces a new `ExecutionTrace` class to manage trace lifetimes, enhancing the overall telemetry framework.

Session spans inherit application parent
High Severity
When a TraceSession is active, operation() and _start_span still start spans from the process-wide OTel context. An application parent that is unsampled makes the session ParentBased(ALWAYS_ON) sampler drop the whole execution trace, so Wharf never receives it. A sampled application parent instead attaches CrewAI spans to that foreign trace, so Wharf sees a tree whose parent was never exported.

Ephemeral share drops open spans
Medium Severity
On a successful ephemeral run, buffer.share() closes the in-memory buffer before session.shutdown() ends leftover active_spans. Those late span.end() calls hit a closed EphemeralSpanBuffer and are discarded, so incomplete operations never appear in the consented upload even though shutdown marks them as ERROR.

HITL pause discards execution traces
High Severity
When a flow catches HumanFeedbackPending and returns it as a successful pause, end_execution still reads that exception from sys.exc_info() in the enclosing finally and treats the run as failed. Ephemeral buffers are discarded without a consent prompt, and session shutdown records an error, even though operation already treats this as expected control flow.

Fall back to the defaults when the limit env vars are not valid integers.
int(os.getenv(...)) raises ValueError for a non-numeric value such as CREWAI_EPHEMERAL_TRACE_MAX_SPANS=1_000_spans or 8MB. lib/crewai/src/crewai/execution.py lines 138-140 enter ephemeral_tracing through stack.enter_context(...) with no handler around it, so a typo in a telemetry-only variable aborts the user's execution.
_max_attr_bytes in lib/crewai/src/crewai/telemetry/tracing/gen_ai_shapes.py lines 378-386 already falls back to its default on ValueError. Use the same behavior here.

Report .size in bytes so it matches .original_size_bytes.
_payload_size returns len(payload), which counts characters. truncate_attr computes <attr>.original_size_bytes with _byte_len, which counts UTF-8 bytes. For any non-ASCII payload the two attributes use different units, so a consumer that compares gen_ai.input.messages.size against gen_ai.input.messages.original_size_bytes computes a wrong truncation ratio.

Avoid initializing TraceCollectionListener only to access batch_manager. On first construction, BaseEventListener.__init__ calls setup_listeners(crewai_event_bus) before _initialized is set. Enabled tracing can therefore register handlers on the global event bus that persist into later tests. Reuse the existing listener or isolate and clean up its handlers.

Update the test setup around TraceCollectionListener and batch_manager to reuse
an existing listener instance instead of constructing a new
TraceCollectionListener solely to access batch_manager. Ensure any listener
created for this test is isolated and its event-bus handlers are cleaned up so
setup_listeners does not leave global registrations affecting later tests.

Sensitive Data Exposure
Reachability: External
Exploitability: Moderate
CWE: CWE-319 — Cleartext Transmission of Sensitive Information
Reject HTTP collector grants before forwarding the bearer token.
TraceGrantClient.create accepts http collector URLs, and GrantSpanExporter forwards the bearer token to the configured endpoint. An HTTP grant can expose the token on an unencrypted hop. Require https in grant validation and add a regression test that an HTTP grant raises TraceGrantError without creating an exporter.

Summary
Verification
Tests added or updated for the changed behavior
Relevant tests and quality checks pass locally
Post-merge regression run: 308 tests passed across execution export, native OTel, execution UUID, conversational Flow, and interception suites.
Expanded validation: 779 OSS tests passed across targeted runs, with 2 skipped; 326 enterprise companion tests passed against the shared OSS source.
Legacy tracing tests passed separately after a combined-run shared sleep-mock flake.
Merge commit hooks passed: Ruff, Ruff formatting, and mypy.
Grant/export tests use synthetic credentials and fake or in-memory collectors.
Additional context
Note
Medium Risk
Touches core kickoff paths, async event dispatch, and optional upload of locally buffered traces that may contain prompts/outputs; behavior should be no-op when tracing is disabled.
Overview
Adds native OpenTelemetry spans across crew kickoff, flow/method execution, tasks, agents, lite-agent kickoff, LLM calls, memory, knowledge, A2A delegation, and guardrails via a shared
operation()helper, with execution UUID attributes on spans.Execution lifecycle now starts and tears down tracing in
begin_execution/end_execution: authenticated runs use grant-based OTLP export; unauthenticated runs buffer spans locally and only upload after an explicit share prompt (prompt_user_for_trace_viewing(sharing=True)).TraceGrantErrorbefore a token is minted propagates without being swallowed as a generic kickoff failure.Event pipeline changes keep trace trees intact: async bus handlers re-attach the caller OTel context, events are recorded on the active trace session on the execution thread, and
TraceCollectionListenerskips its legacy handlers when a trace session is already active.Deferred conversational flows can hold an
ExecutionTraceacross turns and finalize it infinalize_session_traces, with guards so batch finalization does not fight the new session path.Reviewed by Cursor Bugbot for commit 1a2027a. Bugbot is set up for automated code reviews on this repo. Configure here.
