[jira] [Created] (KAFKA-8360) Docs do not mention RequestQueueSize JMX metric

Charles Francis Larrieu Casias created KAFKA-8360:
-----------------------------------------------------

             Summary: Docs do not mention RequestQueueSize JMX metric
                 Key: KAFKA-8360
                 URL: https://issues.apache.org/jira/browse/KAFKA-8360
             Project: Kafka
          Issue Type: Improvement
          Components: documentation, metrics, network
            Reporter: Charles Francis Larrieu Casias


In the [monitoring documentation|[https://kafka.apache.org/documentation/#monitoring],] there is no mention of the `kafka.network:type=RequestChannel,name=RequestQueueSize` JMX metric. This is an important metric because it can indicate that there are too many requests in queue and suggest either increasing `queued.max.requests` (along with perhaps memory), or increasing `num.io.threads`.
