NameTypeDescription
kafka.server:type=MetadataLoader,name=FinalizedLevel,featureName=XIntegerShortThe finalized value of the feature level for a feature named "X".
kafka.server:type=node-metrics,name=minimum-supported-level,feature-name=XIntegerShortThe minimum supported feature level for a feature named "X" on the node.

kafka.server:type=node-metrics,name=maximum-supported-level,feature-name=X

IntegerShortThe maximum supported feature level for a feature named "X" on the node.

The FinalizedLevel  metric will report the finalized feature level for each production feature if it exists. If the a feature level is not set, the metric will return a value of 0, since that means the feature is not enableddoes not have a finalized level, it will not have an associated FinalizedLevel metric. Similarly, if the finalized level of the metric is "removed" by setting it to 0, the associated FinalizedLevel metric will also be removed. This does not apply to metadata.version , whose minimum version is 7. This metric should still reside in the MetadataLoader metric group because its value is derived from the metadata log's feature records.
