How to enable Druid Metric emission?

Hi guys:
In the introduce page of druid metric(, it said

Metrics are emitted as JSON objects to a runtime log file or over HTTP (to a service such as Apache Kafka). Metric emission is disabled by default.

     But I have not found the way to enable metrics emission. I will appreciate very much with your help.

You need to configure one of the metric emitter to enable metrics in druid.
For more information on how to configure a emitter and which all are available please refer to “Enabling Metrics” section

Apart from the core emitters that are part of druid there are few more contributions from third party,one of such emitters is Graphite emitter.
