--------------------------------------
Assignee: PoAn Yang
> Inconsistent casing in Selector metrics tags
> --------------------------------------------
>
> Key: KAFKA-17027
> URL: https://issues.apache.org/jira/browse/KAFKA-17027
> Project: Kafka
> Issue Type: Improvement
> Components: core, metrics
> Reporter: Mickael Maison
> Assignee: PoAn Yang
> Priority: Major
>
> When creating metric tags for a Selector instance, we use "broker-id" in
> ControllerChannelManager, BrokerBlockingSender and ReplicaFetcherBlockingSend
> but we use "BrokerId" in NodeToControllerChannelManagerImpl.
> Not only these casing are inconsistent for metrics tags for the same
> component (Selector) but it looks like neither match the casing the use for
> other broker metrics!
> We seem to always use lower camel case for tags for broker metrics. For
> example, we have "networkProcessor", "clientId", "delayedOperation",
> "clientSoftwareName", "clientSoftwareVersion" as tags on other metrics.
> Fixing this will require a KIP.
