-----------------------------
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.
