Dashboarding With Grafana

Once Prometheus is up and running, Grana can be configured to monitor and visualize Ozone metrics.

Add Prometheus as a data source

In the Grafana web UI, go to Add Data Sources and then select Prometheus.

Enter the Prometheus hostname/port in the HTTP. For example, http://localhost:9094 (verify the port used by looking at Prometheus command line flags -web.listen-address. The port can also be found from Prometheus web UI → Status → Command-Line Flags.)

Choose Prometheus type: Prometheus

Choose Prometheus version: 2.37.x

Finish the setup by clicking on Save and Test.
