Instrument RSocket Requester for Observability

[riko-traveloka]

Hi team, until Spring Boot 2.4.0, there's no metrics auto-configuration for RSocketRequester. Would be nice if there's metrics auto-configuration so that we have visibility over the interaction (request-response, fire-forget, etc), both count and latency.

I think this is a duplicate of spring-projects/spring-boot#16282.

I'm not sure this is a duplicate. AIUI, spring-projects/spring-boot#16282 is about making the Actuator's endpoints available over RSocket and this issue is about RSocket-related metrics.

Hi @mbhave, what @wilkinsona said is right. This issue is about enabling RSocketRequester metric and auto-configuration, and not about making actuator available over RSocket.

Currently RSocketRequester doesn't send any metrics (count and latency) CMIIW, and also there's no clean way to add metrics (no customizer).

Maybe just ignore the "actuator" part of this issue to remove confusion.

Thanks for the clarification @riko-traveloka. I have reopened the issue.
