How to monitor JMX metrics of Kafka broker on command line?

A Kafka cluster can be monitored in granular detail via the JMX metrics it exposes. Usually an external GUI or application like jconsole needs to be hooked up to a broker's exposed JMX_PORT in order to view these metrics.

Is there a way that I can view a broker's JMX metrics in an SSH session, via STDOUT? Is there a native Kafka command that I can run to view these metrics?

Solution

  • Download the jar located here:

    https://sourceforge.net/projects/cyclops-group/files/jmxterm/1.0-alpha-4/

    On the machine, then run:

    wget https://sourceforge.net/projects/cyclops-group/files/jmxterm/1.0-alpha-4/ -o jmxterm.jar

    java -jar jmxterm.jar

    >open localhost:$jmx_port

    Help will give you what you need after that :)

    Save this jar somewhere useful, I use it nearly every day.
