Lixin Yao created KAFKA-15969:
---------------------------------
Summary: Align RemoteStorageThreadPool metrics name with KIP-405
Key: KAFKA-15969
URL: https://issues.apache.org/jira/browse/KAFKA-15969
Project: Kafka
Issue Type: Bug
Components: metrics
Affects Versions: 3.6.0
Reporter: Lixin Yao
Fix For: 3.7.0
In KIP-405, there are 2 metrics defined below:
^kafka.log.remote:type=RemoteStorageThreadPool,
name=RemoteLogReaderTaskQueueSize^
and
^kafka.log.remote:type=RemoteStorageThreadPool,
name=RemoteLogReaderAvgIdlePercent^
However, in Kafka 3.6 release, the actual metrics exposes are:
^org.apache.kafka.storage.internals.log:name=RemoteLogReaderAvgIdlePercent,type=RemoteStorageThreadPool^
^org.apache.kafka.storage.internals.log:name=RemoteLogReaderTaskQueueSize,type=RemoteStorageThreadPool^
The problem is the bean domain name is changed from ^{{kafka.log.remote}}^ to
{{{}^org.apache.kafka.storage.internals.log^{}}}. And the type name is also
changed.
We should either update the metrics path in KIP, or fix the path in the code.
