> Currently controller appends the requests to brokers into controller channel manager queue during state transition. i.e. the state transition are propagated asynchronously. We need to track the request queue time on the controller side to see how long the state propagation is delayed after the state transition finished on the controller.
> We also want to have metrics to monitor the ControllerEventManager queue size and the average time it takes for a event to wait in this queue before being processed.
> See https://cwiki.apache.org/confluence/display/KAFKA/KIP-237%3A+More+Controller+Health+Metrics for more detail.
