enhancement: add environment-backed exporter headers to direct APIs - #901
Conversation
Signed-off-by: Eric Evans <194135482+ericevans-nv@users.noreply.github.com>
WalkthroughOpenTelemetry trace, log, and metric configurations now support environment-backed exporter headers across Rust, FFI, Go, Node.js, and Python APIs. Values resolve at subscriber construction, undergo validation, and remain excluded from telemetry payloads and diagnostics. ChangesOpenTelemetry header resolution
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to Environment-backed headers are resolved during subscriber construction, so missing required variables can cause configuration failure; the documentation also does not fully state that precondition or show the Go usage. This is a bounded configuration and documentation risk that warrants owner follow-up but does not block merging. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@docs/configure-plugins/observability/openinference.mdx`:
- Line 74: Update the observability configuration documentation to cover Go’s
HeaderEnv API alongside the existing Python, Node.js, and Rust examples. Add an
accurate Go example or authoritative reference showing construction-time
configuration and the same secret-handling semantics, using the current public
API.
- Around line 74-75: Update the direct OpenTelemetrySubscriber examples around
config.header_env and OpenTelemetrySubscriber construction to state that
OTEL_AUTHORIZATION must be set to the complete, nonblank authorization header
value before constructing the subscriber; note that header_env is resolved
during construction and a missing variable returns an error, without including
any secret value.
In `@docs/configure-plugins/observability/opentelemetry.mdx`:
- Around line 726-729: The documentation describing environment values must use
the defined whitespace constraint: replace “unpadded” in the header_env
validation description with “no leading or trailing whitespace” or the exact
term used by the implementation, while preserving the other validation
requirements.
In `@go/nemo_relay/otel_signals_test.go`:
- Around line 223-230: Extend the test around NewOpenTelemetryLogSubscriber and
NewOpenTelemetryMetricSubscriber with localhost exporters that capture outbound
requests; change the x-relay-route environment after construction, then assert
both subscribers send the activation-time header value rather than the later
environment value. Also verify the resolved value is absent from exported
payloads and diagnostics.
Apply the same fix in `@python/tests/test_types.py` around lines 619 - 655: Covers
the corresponding Python log and metric subscriber tests with the same missing
request-level and snapshot assertions.

Learning: Within the observability Rust modules, keep signal-generic helpers such as `build_grpc_metadata`, `record_signal_runtime_diagnostic`, and `resolve_http_signal_endpoint` in `otel_signal`. The `otel_logs`, `otel_metrics`, and plugin-routing consumers should depend on these shared helpers without introducing a metrics-to-logs module dependency.

LGTM from me. I left one small coverage nit. Of the CodeRabbit notes, I think the OpenInference page should point readers to the shared header_env construction and validation behavior, and “unpadded” should be replaced with “no leading or trailing whitespace.” I would treat the Go-doc and per-signal outbound-test requests as optional follow-up hardening.

Overview
Direct OpenTelemetry subscribers accepted resolved static headers, but did not provide the environment-backed header configuration already available to declarative exporter configuration.
This adds consistent
header_envsupport to direct trace, log, and metric APIs across Rust, Python, Node.js, and Go. Environment values are resolved once when the subscriber is constructed and are used only as outbound exporter headers.Details
headersbehavior.headersandheader_env, including ASCII case collisions.Validation completed against the committed implementation:
header_envtests: 11 passed.PR-readiness limitation:
just test-ruststopped in the unchangednemo-relay-cli --libtest surface while a Cursor-managed Relay listener was active. The remaining full language matrix and all-file pre-commit were not repeated under the approved validation waiver.Where should the reviewer start?
Start with
crates/core/src/observability/otel_signal.rs, which implements the shared validation and activation-time resolution contract. Then reviewcrates/core/tests/unit/observability/otel_tests.rsfor the real localhost request, snapshot, collision, invalid-value, and non-disclosure coverage.Related Issues: (use one of the action keywords Closes / Fixes / Resolves / Relates to)
