Dashboarding With Grafana

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

Grafana Installation & Startup​

Follow the installation steps from official docs. Download and install the open-source edition of Grafana on the cluster host. Apache Ozone supports Grafana version 13 and above (docker compose uses grafana/grafana:13.0.1-security-01).

Start Server: Start the server on the same host, and check the status. It should be active (running).

sudo systemctl start grafana-server
sudo systemctl status grafana-server

Access the Grafana web UI, The default port used is 3000. Visit http://<hostname>:3000.

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.
