-----------------------------

             Summary: Kafka 4.0+ monitoring documentation still includes some controller metrics only supported in ZK mode
                 Key: KAFKA-20238
                 URL: https://issues.apache.org/jira/browse/KAFKA-20238
             Project: Kafka
          Issue Type: Improvement
          Components: docs
    Affects Versions: 4.1.1, 4.1.0, 4.0.1, 4.0.0
            Reporter: mapan


Kafka 4.0+ removed support for ZK mode, but the [monitoring.md documentation|https://kafka.apache.org/39/operations/monitoring/#security-considerations-for-remote-monitoring-using-jmx] for 4.0+ still includes some controller metrics that are only supported in ZK mode:
 * RequestRateAndQueueTimeMs
 * EventQueueSize
 * LeaderElectionRateAndTimeMs
 * ReplicasIneligibleToDeleteCount
 * ReplicasToDeleteCount
 * TopicsIneligibleToDeleteCount
 * TopicsToDeleteCount

These metrics should either be implemented for KRaft mode or removed from the documentation.
