I used the attached to define the service name for the tomcat application for opendistro trace analytics. I am using otlp collector to receive and exporting to Data prepper. On the Kibana UI, I see the traces but the service name dont show up.

See attached . The javaparameters where I defined the service name as per the docuumentation

export CATALINA_OPTS=“$CATALINA_OPTS -Dotel.resource.attributes=service.name=SuperCarsTrace”

What am getting wrong?

Hi @chidex, which version of Trace Analytics and data-prepper are you on? And do you see any errors in developer tools console when you go to the Services page?

Thanks

Hmm, could you check that serviceName field is not empty in your otel-v1-apm-span-* and otel-v1-apm-service-map indices? Or if there is no sensitive information, could you also share some sample data from these indices? I can try to reproduce the issue on my end.

Hi
I found that single services would not appear at Services dashboard,Multiple services that have call relationship can show there.
My test is like this, don’t know how to fix it?
My env: OTelcol 0.55.0 data prepper: 1.5.0 OpenSearch+dashboard:2.01
