chore(telemetry): track parent processes across forks by mabdinur · Pull Request #16839 · DataDog/dd-trace-py

mabdinur · 2026-03-10T18:56:27Z

Description

Implements session identifier headers for instrumentation telemetry as part of the Stable Service
Instance Identifier RFC. Each telemetry request now includes:

DD-Session-ID: current process runtime ID (always present)
DD-Root-Session-ID: original ancestor's runtime ID (forked processes only)
DD-Parent-Session-ID: immediate parent's runtime ID (forked processes only)

This enables the backend to correlate related processes across fork trees without relying on
runtime_id regeneration.

_PARENT_RUNTIME_ID tracking is added to ddtrace/internal/runtime alongside env var seeding
(_DD_ROOT_SESSION_ID, _DD_PARENT_SESSION_ID) to support multiprocessing spawn/forkserver
start methods.

Testing

tests/tracer/runtime/test_runtime_id.py::test_parent_runtime_id — validates
get_parent_runtime_id() is None in the root process and correctly tracks the immediate
parent across nested forks
tests/telemetry/test_telemetry.py::test_session_id_headers_across_forks — uses the test
agent to capture telemetry requests from a parent → child → grandchild fork tree and asserts
the correct structure of all three session headers

Risks

The new headers are additive — existing payload fields (runtime_id) are unchanged. No impact
to profiling, DI, crash tracking, or remote config.

Additional Notes

DD-Root-Session-ID and DD-Parent-Session-ID are omitted from root process requests per the
RFC spec: if DD-Root-Session-ID is absent, the backend assumes root_session_id == session_id.

## Summary Implements the [Stable Service Instance Identifier RFC](https://docs.google.com/document/d/1ECKj9_NnwaKYtFqm3p3Rlpicx5d-OQcdj9kI2jvRqVU) for Go instrumentation telemetry. - **`DD-Session-ID`**: always present on every telemetry request, set to the current `runtime_id` - **`DD-Root-Session-ID`**: present only in child processes, inherited via `_DD_ROOT_GO_SESSION_ID` env var. Omitted when equal to session ID — backend infers root = self when absent - **Auto-propagation**: `globalconfig.init()` sets `_DD_ROOT_GO_SESSION_ID` in `os.Environ()` so child processes spawned via `os/exec` inherit it automatically without any user-side calls ## Changes - `internal/globalconfig/globalconfig.go`: adds `rootSessionID` field, `init()` reads/sets `_DD_ROOT_GO_SESSION_ID` (internal env var, not in supported_configurations), `RootSessionID()` getter - `internal/telemetry/internal/writer.go`: adds `DD-Session-ID` (always) and `DD-Root-Session-ID` (child processes only) to pre-baked telemetry headers - Tests for both globalconfig (including cross-process propagation) and writer ## Related - System-tests PR: DataDog/system-tests#6510 - Node.js PR: DataDog/dd-trace-js#7821 - dd-trace-py fork tracking: DataDog/dd-trace-py#16839 - dd-trace-py spawn tracking: DataDog/dd-trace-py#16842 Co-authored-by: ayan.khan <[email protected]>
