Hi, Srinivas Devaki ! There are Kafka JMX metrics - NumGroupsCompletingRebalance and NumGroupsPreparingRebalance. I think you can monitor them by some application and calculate statistic. As for us - we added Jolokia agent to our Kafka docker image and Jolokia expose all JMX metrics via HTTP. We run additional service which gets necessary metrics from this endpoint and analyse them.
