JaegerThe root cause of this issue originates in Jaeger

How to detect:

Distributed traces are not appearing in the Jaeger UI, indicating connectivity issues between Traefik and the Jaeger agent or incorrect tracing configuration.

Recommended action:

Check Jaeger connectivity by examining Traefik logs for jaeger-related errors: kubectl logs -n traefik -l app.kubernetes.io/name=traefik | grep jaeger. Verify the Jaeger agent is running in the observability namespace and that samplingServerURL and localAgentHostPort are correctly configured.
