-------------------------------------
Summary: KRaft Controller Metric MBean names are incorrectly quoted
Key: KAFKA-13137
URL: https://issues.apache.org/jira/browse/KAFKA-13137
Project: Kafka
Issue Type: Bug
Components: controller
Affects Versions: 2.8.0, 3.0.0
Reporter: Ron Dagostino
Assignee: Ron Dagostino
Fix For: 3.0.0
QuorumControllerMetrics is letting com.yammer.metrics.MetricName create the
MBean names for all of the controller metrics, and that adds quotes. We have
typically used KafkaMetricsGroup to explicitly create the MBean name, and we do
not add quotes there. The controller metric names that are in common between
the old and new controller must remain the same, but they are not. For
example, this non-KRaft MBean name:
kafka.controller:type=KafkaController,name=OfflinePartitionsCount
has morphed into this when using KRaft:
"kafka.controller":type="KafkaController",name="OfflinePartitionsCount"
