Kubernetes: Collect metrics from Cassandra via JMX Exporter

[avig...@3base.co.il]

Hi,

We are trying to use JMx Exporter as an HTTP server for our Cassandra that runs on kebernetes as a daemond set.

We use this docker image: https://hub.docker.com/r/sscaling/jmx-prometheus-exporter/

In the logs we see an authentication error:
cassandra kubernetes SEVERE: JMX scrape failed: java.lang.SecurityException: Authentication failed! Credentials required

When disabling the authentication from Cassandra by "JVM_OPTS -Dcom.sun.management.jmxremote.authenticate=false" it works fine.

Is there any way to get it work with the authentication?
How can I set user+psw in the exporter?

Should we use JavaAgent for it? we do not want to run exporter on each pod.

It is recommended to always use the java agent for JMX monitoring, see https://www.robustperception.io/monitoring-cassandra-with-prometheus/
