LangSmith integration

LangSmith cost attribution integration

LangSmith gives trace depth. Opsmeter connects that depth to budget and ownership workflows so teams can explain the bill, not just the trace.

Trace-rich observability does not automatically provide margin and budget ownership clarity.

Why default tooling falls short

Trace-rich observability does not automatically provide margin and budget ownership clarity.

Trace + spend narrative

Connect execution traces with cost/request and budget posture in one review loop.

Faster cost diagnosis

Move from trace anomaly to endpoint and tenant cost owner quickly.

Production governance

Use attribution and budget controls alongside debugging workflows.

Setup checklist

Step 1

Expose trace and run identifiers

Carry LangSmith trace IDs with each model call usage payload.

Step 2

Attach ownership metadata keys

Add endpoint, tenant, user, and promptVersion fields to every ingest row.

Step 3

Correlate in Opsmeter views

Use endpoint and tenant concentration views to interpret trace-linked cost deltas.

How Opsmeter operationalizes this path

Carry LangSmith trace IDs

Attach trace/run IDs in ingest metadata so cost rows can be correlated with traces.

Include ownership tags

Send endpoint, tenant, user, and prompt identifiers with usage fields.

Operate from shared cost views

Investigate trace-linked spend deltas in endpoint and tenant dashboards.

Ship attribution without gateway rewrites

No proxy rewrite required. Keep your current app path and enrich request metadata.
