[jira] [Created] (HDDS-1710) Publish JVM metrics via Hadoop metrics

Elek, Marton created HDDS-1710:
----------------------------------

             Summary: Publish JVM metrics via Hadoop metrics
                 Key: HDDS-1710
                 URL: https://issues.apache.org/jira/browse/HDDS-1710
             Project: Hadoop Distributed Data Store
          Issue Type: Improvement
          Components: om, Ozone Datanode, SCM
            Reporter: Elek, Marton
            Assignee: Elek, Marton


In ozone metrics can be published with the help of hadoop metrics (for example via PrometheusMetricsSink)

The basic jvm metrics are not published by the metrics system (just with JMX)

I am very interested about the basic JVM metrics (gc count, heap memory usage) to identify possible problems in the test environment.

Fortunately it's very easy to turn it on with the help of org.apache.hadoop.metrics2.source.JvmMetrics.
