Subject interpretation of ErrorsPerSec JMX metric
Date Wed, 05 Jun 2019 00:44:51 GMT
I started examining metrics on one of the nodes in my Kafka cluster
and I am confused about one of the metrics that is exposed.
Specifically, this metric:
kafka.network:name=ErrorsPerSec,error=NONE,request=Fetch,type=RequestMetrics

The name is ErrorsPerSec but error is set to "NONE". What is the
correct interpretation of what this metric represents? Are these
errors (as the name implies) or are they not errors (as the value of
error implies)?

If they are errors, my next question is how I can uncover what is
causing the error. I don't see anything relevant in the Kafka logs.

Here is how I am accessing the metric:

bin/kafka-run-class.sh kafka.tools.JmxTool --jmx-url
service:jmx:rmi:///jndi/rmi://localhost:9999/jmxrmi --object-name
kafka.network:name=ErrorsPerSec,error=NONE,request=Fetch,type=RequestMetrics
--attributes Count

"time","kafka.network:type=RequestMetrics,name=ErrorsPerSec,request=Fetch,error=NONE:Count"
