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

             Summary: metrics exposed via JMX shoud be configurable
                 Key: KAFKA-9106
                 URL: https://issues.apache.org/jira/browse/KAFKA-9106
             Project: Kafka
          Issue Type: Improvement
          Components: metrics
            Reporter: Xavier Léauté
            Assignee: Xavier Léauté


Kafka exposes a very large number of metrics, all of which are always visible in JMX by default. On large clusters with many partitions, this may result in tens of thousands of mbeans to be registered, which can lead to timeouts with some popular monitoring agents that rely on listing JMX metrics via RMI.

Making the set of JMX-visible metrics configurable would allow operators to decide on the set of critical metrics to collect and workaround limitation of JMX in those cases.
