-----------------------------------------------------
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`.
