[jira] [Commented] (KAFKA-15969) Align RemoteStorageThreadPool metrics name with KIP-405

["Colin McCabe (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-15969?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17872494#comment-17872494 ] 

Colin McCabe commented on KAFKA-15969:
--------------------------------------

Kafka 3.6 was released quite a while ago. Changing the metric names at this point would require a KIP.

Moving to 4.0 since we are past KIP freeze for 3.9.

>                 URL: https://issues.apache.org/jira/browse/KAFKA-15969
>             Project: Kafka
>          Issue Type: Bug
>          Components: metrics
>    Affects Versions: 3.6.0
>            Reporter: Lixin Yao
>            Priority: Minor
>             Fix For: 3.9.0

>   Original Estimate: 1h
>  Remaining Estimate: 1h

> 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.
