elek opened a new pull request #994: HDDS-1710. Publish JVM metrics via Hadoop metrics
URL: https://github.com/apache/hadoop/pull/994
 
 
   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.
   
   See: https://issues.apache.org/jira/browse/HDDS-1710
