Are there any specific implementation requirements?

@okareyou Welcome. You may refer to https://eventmesh.apache.org/docs/design-document/observability/metrics-export/ chapter.

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:

eventmesh/eventmesh-trace-plugin/eventmesh-trace-api/build.gradle

Lines 23 to 24 in e349def

	implementation 'io.opentelemetry:opentelemetry-api'
	implementation 'io.opentelemetry:opentelemetry-sdk'

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.
