Manikumar resolved KAFKA-3139.
------------------------------
Resolution: Fixed
Fixed in KAFKA-4252
> JMX metric ProducerRequestPurgatory doesn't exist, docs seem wrong.
> -------------------------------------------------------------------
>
> Key: KAFKA-3139
> URL: https://issues.apache.org/jira/browse/KAFKA-3139
> Project: Kafka
> Issue Type: Bug
> Reporter: James Cheng
>
> The docs say that there is a JMX metric
> {noformat}
> kafka.server:type=ProducerRequestPurgatory,name=PurgatorySize
> {noformat}
> But that doesn't seem to work. Using jconsole to inspect our kafka broker, it
> seems like the right metric is
> {noformat}
> kafka.server:type=DelayedOperationPurgatory,name=PurgatorySize,delayedOperation=Produce
> {noformat}
> And there are also variants of the above for Fetch, Heartbeat, and Rebalance.
> Is the fix to simply update the docs? From what I can see, the docs for this
> don't seem auto-generated from code. If it is a simple doc fix, I would like
> to take this JIRA.
> Btw, what is NumDelayedOperations, and how is it different from PurgatorySize?
> {noformat}
> kafka.server:type=DelayedOperationPurgatory,name=NumDelayedOperations,delayedOperation=Produce
> {noformat}
> And should I also update the docs for that?
