OpenShift Monitoring Grafana Dashboard

Tutorial to use custom Grafana Dashboard to explore OpenShift metrics from a Prometheus datasource.

This guide will use a Prometheus endpoint from an OpenShift CI job, exploring the exported Prometheus database from a OpenShift/Prow CI job using the Prometheus API exposed by PromeCIeus.

Steps to use custom grafana:

1) Restore the Prometheus datasource from a CI execution

• Find the Prow job
• Click in the lens "Debug Tools", then PromeCIeus
• Paste the Job URL
• Click in Generate to restore the the Prometheus database to an instance
• Copy the URL (without path /graph) for later

2) Deploy Grafana Instance using PromeCIeus as Datasource

• Create the Grafana Instance (skip if you already have one)

podman run -d --name=grafana -p 3000:3000 grafana/grafana

• Open the Grafana creating a new Prometheus datasource, naming it as prometheus.
• Paste the PromeCIeus URL (without path /graph. example: https://ntpvpgpq-promecieus.apps.cr.j7t7.p1.openshiftapps.com)
• Download the Dashboard JSON file grafana-dashboard-promecleus.json, and import to Grafana
• Adjust the Dashboard timeframe for your job execution and be happy.
