I checked out the EventMesh code and it looks like it's using OpenTelemetry for both metrics and tracing. Does that mean it's already set up with the OpenTelemetry SDK? Could I be missing something? Any advice would be great.

I'm not familier with trace-plugin yet. opentelemetry-sdk has been introduced in trace-plugin api:

https://github.com/apache/eventmesh/blob/e349def6a4eba61b94a8e5b8aeb4ddf9745cfbe7/eventmesh-trace-plugin/eventmesh-trace-api/build.gradle#L23-L24

May be we need some enhancement for trace-plugin? @qqeasonchen

@okareyou You may want to look at the trace-plugin to see if it has implemented the tracing collecting feature, and if this feature supports OpenTelemetry.
