How to configure druid metrics and the linux machine on which it is hosted?

Hello!
Introduced with next pages of documentation:
https://druid.apache.org/docs/latest/operations/metrics.html#sql-metrics
https://druid.apache.org/docs/latest/configuration/index.html#logging-emitter-module
And I do not understand how to setup sending metrics for Grafana.

Of course, I set parameters into /apache-druid-0.22.1/conf/druid/single-server/micro-quickstart/_common/common.runtime.properties file. And now I have:

druid.monitoring.emissionPeriod=PT30S
druid.monitoring.monitors=["org.apache.druid.java.util.metrics.SysMonitor","org.apache.druid.java.util.metrics.JvmMonitor"]
druid.emitter=noop
druid.emitter.logging.logLevel=info

But I do not understand how to get druid and system info data. May be changing druid.emitter to logging help me?

I’m not sure that’s supported:

It supports timeseries, group by, topN and Select queries.

Lot of features might still not be implemented. Your contributions are welcome.

Correct. noop, the default which you’re showing in your common runtime properties, disables metric emission. logging emits logs using Log4j2, and it’s one of several emitters available.
