Hi Mahsa, I see that you are proposing to add the metrics ControllerThreadIdleRatio to the kafka.controller:type=ControllerEventManager group. The word controller is already part of the group and namespace. How about just calling it AvgIdleRatio? That better matches the name used by the kraft actor (poll-idle-ratio-avg) and the name used by the request handler (RequestHandlerAvgIdlePercent).
Thanks, -- -José
