Failed to start grafana. error: section “tracing.opentelemetry.jaeger” does not exist

  • Did you follow any online instructions? If so, what is the URL?

Looks like the defaults.ini was not upgraded by the installer to include the [tracing.opentelemetry.jaeger] and [tracing.opentelemetry.otlp] sections.

After copying the [tracing.opentelemetry.jaeger] and [tracing.opentelemetry.otlp] sections from the sample.ini into the defaults.ini; commenting out the deprecated [tracing.jaeger] settings and uncommenting the [tracing.opentelemetry.jaeger] settings, the Grafana instance is now up and running on
