There was a problem hiding this comment.
Great PR and a good start.
I've added a couple of notes and questions.
It's been a while since I worked with this.

New activemq-opentelemetry module that instruments the broker using the OpenTelemetry API. The plugin traces send (PRODUCER), dispatch (CONSUMER), and acknowledge (INTERNAL) operations with W3C TraceContext propagation and standard OTel messaging semantic conventions. Depends on opentelemetry-api only; users bring their own SDK and exporter at runtime. Included in the distribution with example configuration.
- Fix OTel semantic convention attribute names: messaging.system -> messaging.system.name messaging.operation -> messaging.operation.type messaging.client_id -> messaging.client.id (dot notation) - Initialize propagator and tracer once in constructor instead of per-invocation - Bound dispatchSpans map to prevent unbounded growth / span leaks; oldest span is ended and evicted when the limit is exceeded - Add comment explaining setMarshalledProperties(null) in TextMapSetter - Replace Thread.sleep() in tests with Wait.waitFor() pattern - Document topic fan-out span behavior in class Javadoc

@cshannon wdyt about this one for 6.3.0? |
Contributor
I haven't looked at this at all and this definitely needs to wait. Did
I think 6.4.0 makes more sense, I don't think anyone else has paid attention to this (I know I haven't) and adding a major new framework like this is a pretty big deal, even if it's off by default. I think it would be good to have some more time. |

Depends on opentelemetry-api only; users bring their own SDK and exporter at runtime. Included in the distribution with example configuration. Maybe we should add a default SDK/exporter in the ActiveMQ distribution, just wondering 😄
