Problem

Without service.instance.id, a restart or a second process of the same service looks like one instance in a backend, and the resources one process exports cannot be joined.

Change

  • Every exported resource carries service.instance.id:
    • Server and desktop main process: one random id per Node process (processServiceInstanceId in packages/shared/src/observability.ts), shared by all of that process's resources, including the server's relay resources.
    • UI: one id per page load.
    • Mobile: the Expo session id.
  • On the server and desktop, a service.instance.id in OTEL_RESOURCE_ATTRIBUTES wins. The server relay layers read it from the already-parsed ServerConfig instead of re-parsing the environment.

Verification

  • observability.test.ts: the id is stable per process and an operator value wins.
  • serverLogger.test.ts: the exported server resource carries the operator id.
  • Runtime: isolated server exporting OTLP to a local capture endpoint.
default:
  service.instance.id = 018f10f5-589f-4c73-ae75-8e13465ff7af
  service.name = t3code-server
  service.namespace = t3code
OTEL_RESOURCE_ATTRIBUTES=service.instance.id=pod-7:
  service.instance.id = pod-7
  • Lint currently fails on main for files this PR does not change.

Originally opened by @yordis; taken over by the maintainers, merged with main's t3code.* keys, with the web helper inlined and the relay env re-parse dropped.

This changes the server's exported telemetry resource, but the focused tests cover only the ID helper, desktop, and mobile; none checks the server resource. Could you add a focused test for otlpResource that verifies the generated instance ID and the operator-provided override? That will protect the server's resource-attribute wiring. The fix requires a test-file change, so there is no single-hunk suggestion here.

Walkthrough

Telemetry resources across desktop, mobile, server, and web now include service.instance.id. Server and desktop use a shared resolver that honors configured attributes or reuses a process UUID. Mobile uses the Expo session, and web generates a page-load UUID.

Changes: Telemetry service instance IDs

Layer / File(s) Summary
Shared ID resolution and relay resource
packages/shared/src/observability.ts, packages/shared/src/observability.test.ts, packages/shared/src/relayTracing.ts
The shared resolver returns a configured service instance ID or generates and reuses a UUID. Relay tracing resources accept and export the ID.
Desktop and server resource wiring
apps/desktop/src/app/DesktopObservability.ts, apps/server/src/config.ts, apps/server/src/cloud/relayTracing.ts, apps/server/src/serverLogger.test.ts, docs/operations/observability.md
Desktop and server resources use the resolver. Server relay layers pass the ID to relay tracing. The test checks the exported log attribute, and the documentation describes runtime ID values and overrides.
Mobile and web tracing resources
apps/mobile/src/features/observability/tracing.ts, apps/mobile/src/features/observability/tracing.test.ts, apps/web/src/observability/clientTracer.ts, apps/web/src/observability/clientTracing.ts, apps/web/src/lib/runtime.ts
Mobile tracing uses the Expo session ID. Web tracing uses a page-load UUID for client and relay resources. The mobile test checks the exported trace attribute.

Full details: Description check

Explanation

The description covers the problem, the change, and verification, so it is mostly complete. It does not link a triaged issue or maintainer-approved discussion in the Scope and approval section, which the template requires. The author also left the Problem section as a single sentence that does not state reproduction steps or environment, though the template asks for them where relevant. Those gaps are non-critical for this check. The verification section is concrete: it names the tests, gives a runtime output sample, and reports a known lint failure on main.

Correction to my inline review comment on apps/server/src/config.ts: I overlooked the focused server logger test in apps/server/src/serverLogger.test.ts that asserts the exported resource contains service.instance.id. Please disregard the request for a server resource test; the earlier comment is not a finding.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This is a focused observability fix that adds service-instance identifiers to existing exported resources across the supported clients and server paths. It also introduces a line-scoped static-analysis suppression, and the server resource wiring lacks a focused direct test for both generated and operator-provided IDs.

No code changes detected at 072a285. Prior analysis still applies.

316-340: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Assert the operator-provided desktop instance ID.

The desktop test only checks that the key exists. If DesktopObservability.ts stops passing endpoints.resourceAttributes, processServiceInstanceId generates an ID and the test can still pass. The shared helper test calls the helper directly, so it does not cover desktop wiring.

Configure OTEL_RESOURCE_ATTRIBUTES in this test and assert the exact serialized value.

Addressed in the takeover: both server relay layers now take service.instance.id from processServiceInstanceId(config.otelEnvironment.resourceAttributes), so an operator value such as pod-7 matches the server resource. The docs now limit the override to server and desktop. serverLogger.test.ts covers the exported server resource. Resolving these threads.
