Confluent documentation specifically mentions three controller event manager metrics:
- EventQueueProcessingTimeMs
- EventQueueTimeMs
- EventQueueSize
According to this documentation, all three of these should exposed via JMX as MBeans. However, when I pull up jconsole for one of my brokers I only see the two time metrics and not the size metric? Is this configurable? Is the size derivable by diffing counts on the two time metrics? The controller event queue size is cited as an important operational metric in a number of sources.
