Connect an existing runtime

Add Metrune to an API, worker, or Kubernetes service without changing how the workload is hosted.

Choose an instrumentation path

Use the Metrune SDK for agent-aware spans and automatic model instrumentation. Use OpenTelemetry when your service already emits traces or when you need language-neutral context propagation.

Set the environment key

Create a scoped API key in project settings and expose it to the runtime through your existing secret manager. Do not commit keys to source control.

METRUNE_API_KEY=mt_live_••••••••
METRUNE_ENVIRONMENT=production

Propagate run context

Keep the run ID across HTTP requests, queues, and background jobs. Metrune accepts W3C trace context, so existing instrumented services can join the same execution graph.

Verify the connection

Send a test run and confirm the runtime, release, and environment dimensions in Trace Explorer. Then configure sampling and redaction policies before increasing production volume.
