Observability: Tracing JobRunr Jobs Follow this guide to enable and configure distributed tracing for JobRunr Pro jobs using your observability platform of choice.

🔍 API call triggers a job. That job calls another service. Where did it fail?

You lose the trace at the queue. Your job becomes a black box.

Our new Pro guide shows how to fix this.
