Hi, I was wondering if there is any way to monitor Netty Reactor. From the documentation I see that it doesn't have anything to say about Netty Reactor, but Reactor itself seems to be supported experimentally: [Supported technologies | APM Java Agent Reference [1.x] | Elastic](https://www.elastic.co/guide/en/apm/agent/java/current/supported-technologies-details.html#supported-web-frameworks)

Also, is it perhaps possible to use opentelemetry to monitor this instead?  
[https://mvnrepository.com/artifact/io.opentelemetry.instrumentation/opentelemetry-netty-4.1/usages](https://mvnrepository.com/artifact/io.opentelemetry.instrumentation/opentelemetry-netty-4.1/usages)  
If so, does this module can only instrument netty reactor libraries?

Hi @Ivan_Hosea ,

We do support Reactor instrumentation, but only the "core" part that is listed here: [Project Reactor - Documentation](https://projectreactor.io/docs)

We don't have any specific support for Reactor Netty, but it could be relevant to add support for the HTTP client/server parts.

Regarding the OpenTelemetry agent which you refered to, I think the best option is to try it in order to see if it allows to capture what you need.

Elastic APM Server provides an OTLP endpoint ([doc](https://www.elastic.co/guide/en/apm/guide/current/open-telemetry.html)), so you can use it with the data you may be able to capture.
