Is it possible to get JVM metrics like gc time, number of threads , heap / non heap memory etc from pinot-server ? I looked at 1. https://github.com/apache/incubator-pinot/blob/master/pinot-common/src/main/java/org/apache/pinot/common/metrics/ServerMeter.java 2. https://github.com/apache/incubator-pinot/blob/master/pinot-common/src/main/java/org/apache/pinot/common/metrics/ServerGauge.java but did not find much other than

REALTIME_OFFHEAP_MEMORY_USED

Yes. I recommend using JMX exporter to Prometheus and monitoring using Grafana. https://github.com/prometheus/jmx_exporter
