Hi,

I configured metricbeat to pull the metrics from Flink app with Jolokia.  
I have added jolokia java agent to flink and I am able to pull the basic MBean Metrics like memory, CPU, runtime, etc. But apart from these, Flink exports a lot of custom metrics from its JMX.

Any suggestions on how to fetch those custom jmx metrics through jolokia?

The [`jmx` metricset](https://www.elastic.co/guide/en/beats/metricbeat/current/metricbeat-metricset-jolokia-jmx.html) allows for customization of the collected fields. Which you choose to pick up depends on your use-case.

I configured flink to expose the metric in the form of prometheus and used prometheus module in metricbeat to fetch the metrics.
