Have you had experience working with the Jaeger request tracing system?

Jaeger is a distributed tracing system that helps track and visualize the request path through microservices. Experience with Jaeger typically involves integrating SDKs into services to generate spans, configuring agents and collectors, and analyzing data in the Jaeger UI to identify bottlenecks and performance issues.

For example, in a Go application, you can use OpenTelemetry with export to Jaeger to automatically collect traces and see the execution time of each request step.
