> REST Jersey metric names are inconsistent
> -----------------------------------------
>
> Key: KAFKA-17161
> URL: https://issues.apache.org/jira/browse/KAFKA-17161
> Project: Kafka
> Issue Type: Bug
> Components: core
> Affects Versions: 3.6.2
> Reporter: Doug Hoard
> Assignee: Sathishkumar Manimoorthy
> Priority: Minor
>
> *Summary*
> When exporting JMX metrics from a server, REST Jersey metric names are
> inconsistent, resulting in two metrics different metrics with the same value.
> {code:java}
> v3.topics-partitions-reassignment.list.request-total
> v3.topics.partitions-reassignment.list.request-total{code}
> Dash (-) versus period ({{{}.{}}}) between {{topics}} and {{partitions}}
> This most likely affects older versions.
> *Test scenario*
> Install Kafka 3.6.2 with the Prometheus JMX Exporter v1.0.1 and collect
> metrics. The exporter adds a label "_objectname" for metrics that map to the
> same Prometheus name.
> *Example exporter output*
> {noformat}
