Not able to connect/correlate different microservice spans together in one trace Jaeger UI after Opentelemetry migration

[miPlodder]

Recently, I migrated from jaeger-client to Opentelemetry, but now I see jaeger not able to trace and mapping span across different microservice. I followed this https://medium.com/jaegertracing/migrating-from-jaeger-client-to-opentelemetry-sdk-bd337d796759 for the migration.

Is there something extra that needs to be configured in order to map different call to internal microservice in single trace? (as shown in below image)

Note: It works fine in local env (windows machine) with Jaeger running, where it's not working on Jaeger UI deployed on Openshift.

have you added the jaeger propagator per that article?

[jkwatson]

can you verify the right headers are being sent on requests between the services?

[miPlodder]

Can you share some details around what headers needed to be sent b/w the microservices?

[jkwatson]

That depends on whether you're using jaeger propagation or W3C propagation. Are you seeing any tracing headers being sent on requests?

[miPlodder]

• Yep, I see tracing headers uber-trace-id and traceparent in the request headers. Below is a sample header. Can something be concluded from it, regarding my issue?

{
Accept=application/json, 
application/*+json,
uber-trace-id=30a2f1f6a5f66eaa08ec6bc4e293951a:3259101a27246bec:0:0, 
traceparent=00-30a2f1f6a5f66eaa08ec6bc4e293951a-3259101a27246bec-00, 
Connection=Keep-Alive, 
User-Agent=okhttp/4.9.3, 
Host=microserviceB.svc:8443, 
Accept-Encoding=gzip, 
Content-Length=0
}

• Moreover, which classes intercept before every request for OTEL client so that I can DEBUG the flow so that I can see the logic why it's ignoring the headers (sample above)? Or any other way to DEBUG these sort of issues?

[jkwatson]

This headers will be picked up the propagator implementation that is configured into the receiving service. Nothing will automatically intercept the request (unless you're using the otel java agent). You'll have to make sure that the propagators are properly used in the request interceptors.
