Work Description: elek commented on issue #994: HDDS-1710. Publish JVM
metrics via Hadoop metrics
URL: https://github.com/apache/hadoop/pull/994#issuecomment-507479341
> @elek Can this be done for HDDS client as well?
Sure. I added it to the freon.
For simple `ozone sh` it's more tricky as metrics generates additional
logging which may break the existing tests (and can be confusing), but at freon
it's no problem as it's already logging a lot. And metrics is more useful for
freon than shell anyway....

> 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.
