> 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.
