feat(server-utils): Implement orchestrion-based instrumentation for vercel-ai v6 by mydea · Pull Request #21658 · getsentry/sentry-javascript

mydea · 2026-06-19T13:01:53Z

When using orchestrion, this replaces the regular vercelAiIntegration with the channel-variant. This today supports vercel ai v6 and v7 (v5/v4 support TBD).

Test coverage exists and everything passes. This does not add any event processors etc. anymore, everything works inside of the integrations.

OTEL Spans emitted directly by vercel-ai v6 or below are ignored to avoid double instrumentation.

Haven't found any major issues. Tests are failing though and clanker has some objections

+ return isRecord(model) ? asString(model[field]) : undefined;
+}
+
+function asString(value: unknown): string | undefined {


super-l: Maybe it makes sense to outsource these functions in a helper? vercel-ai-dc-subscriber.ts is also using some of the helpers

andreiborza · 2026-07-01T07:46:12Z

+ // A single model instance shared by two concurrent `streamText` calls carries only one
+ // captured-parent slot, so both model calls must still land under their own `invoke_agent` — not
+ // collapse onto whichever operation resolved the shared model last.
+ test.skipIf(version === '7' && nodeVersion === 18)(


q: Why are we skipping this test on v7?

added a better comment here!

andreiborza · 2026-07-01T07:58:58Z

+ * Like the v7 subscriber, each operation channel is wired up via
+ * {@link bindTracingChannelToSpan}, which binds the opened span into the runtime's
+ * async context for the duration of the traced call and ends it when the call
+ * settles. That binding is what lets the model call below find its enclosing
+ * `invoke_agent` span via the active context (see {@link resolveModelCallParent}).


nit: I'd drop this, it doesn't really add much for understanding, it explains bindTracingChannelToSpan which should already be explained elsewhere.

this has all been refactored a bit and is hopefully easier/cleaner to understand now.

This PR just splits up the orchestrion config for instrumentation into a file per instrumentation, making it a bit cleaner and easier to follow. This is on top of #21658
