----------------------------------
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.
