Enabling the metrics system is straightforward by editing the puppet server metrics.conf file located at /etc/puppetlabs/puppetserver/conf.d/metrics.conf.

There are three important settings. At the metrics.server-id one can specify an ID which is later used in the Grafana dashboard. The metrics.registry.puppetserver.reporters.graphite.enabled value must be set to true and the metrics.reporters.graphite hash must mention the graphite hostname and port and the update interval setting:
