NetworkProcessorAvgIdlePercent

Kafka documentation recommends <0.3 for above metric. I assume processor is
busier if this goes below 0.3 and obviously it being < 0.3 for long does
not seem to be a good sign.

What should be our criteria to raise an alert, I though it should  be when
its value goes below 0.3. However, the value seems to be below 0.3 a lot of
the times, almost always if we take samples every five mins. What should be
the threshold to raise an alarm ?

What would be the impact of having this below 0.3 or even zero like most of
the times?

Re: NetworkProcessorAvgIdlePercent

Posted by Jun Rao <ju...@confluent.io>.
Zakee,

It would be useful to get the following.

kafka.network:name=RequestQueueSize,type=RequestChannel
kafka.network:name=RequestQueueTimeMs,request=Fetch,type=RequestMetrics
kafka.network:name=RequestQueueTimeMs,request=Produce,type=RequestMetrics

Thanks,

Jun

Re: NetworkProcessorAvgIdlePercent

Posted by Zakee <kz...@netzero.net>.
Hi Jun,

There are too many KPIs generated by kafka that I can’t monitor them all, I have monitoring a filtered list that I can understand so far.

Which keys are you talking of? Currently I am not monitoring any of below keys but will add only those that are useful.

kafka.network:name=RequestQueueSize,type=RequestChannel
kafka.network:name=RequestQueueTimeMs,request=ConsumerMetadata,type=RequestMetrics
kafka.network:name=RequestQueueTimeMs,request=ControlledShutdown,type=RequestMetrics
kafka.network:name=RequestQueueTimeMs,request=Fetch,type=RequestMetrics
kafka.network:name=RequestQueueTimeMs,request=FetchConsumer,type=RequestMetrics
kafka.network:name=RequestQueueTimeMs,request=FetchFollower,type=RequestMetrics
kafka.network:name=RequestQueueTimeMs,request=Heartbeat,type=RequestMetrics
kafka.network:name=RequestQueueTimeMs,request=JoinGroup,type=RequestMetrics
kafka.network:name=RequestQueueTimeMs,request=LeaderAndIsr,type=RequestMetrics
kafka.network:name=RequestQueueTimeMs,request=Metadata,type=RequestMetrics
kafka.network:name=RequestQueueTimeMs,request=OffsetCommit,type=RequestMetrics
kafka.network:name=RequestQueueTimeMs,request=OffsetFetch,type=RequestMetrics
kafka.network:name=RequestQueueTimeMs,request=Offsets,type=RequestMetrics
kafka.network:name=RequestQueueTimeMs,request=Produce,type=RequestMetrics
kafka.network:name=RequestQueueTimeMs,request=StopReplica,type=RequestMetrics
kafka.network:name=RequestQueueTimeMs,request=UpdateMetadata,type=RequestMetrics


Thanks,

That may be enough. What's the RequestQueueSize and RequestQueueTimeMs?

Re: NetworkProcessorAvgIdlePercent

With ~100G of data being pushed per hour across 35 topics
(replication-factor 3), the NetworkProcessorAvgIdlePercent is mostly
showing below 0.5 sometimes when the producers send on a high rate.
