Hi Kevin, The metrics that you added for supported versions, " kafka.controller:type=KafkaController,name=MaximumSupportedLevel,featureName=X" and "kafka.server:type=broker-metadata-metrics,name=maximum-supported-feature-level,featureName=X", the metric group name doesn't seem accurate. Those metrics are node or software specific. They are not metadata or controller specific. Those metrics are a feature of the released software being used by the node. How about adding a "server-metrics" or "node-metrics" group? Eventually we can use this group to add other values like release version, commit hash, etc.
Thanks, -- -José
