You are right,it gives the count of mesages stored in all topics from the time the Broker service(Kafka) is started and thats why its actually no of msg request coming to each broker.So whenever a broker service is restarted,message count is set to zero. Also this is the reason,msg count doesn't get decrease when msg is deleted from Broker.
