Monitoring demo for Openshift with Prometheus and Grafana

This simple demo has been forked from ConSol Labs. It has been deployed using OKD docker-based cluster launched via oc cluster up

The only step that is not explicitly documented within the former linked blog post is the one for binding the system:auth-delegator with the prometheus service account. It has to be accomplished doing the following:

• oc login -u system:admin
• oc adm policy add-cluster-role-to-user system:auth-delegator system:serviceaccount:prometheus:prometheus

Usage

If we summarize the demo steps you have to follow:

• Deploy the demo application.
• Deploy Prometheus within a separate project.
• Deploy Grafana within a separate project.
• Give Grafana service account view privileges for the prometheusproject.
• Set up Prometheus data source within Grafana.
• Update Prometheus' configuration file (via ConfigMap) for scraping our demo application.
• Update our demo application's Deployment Config for allowing Prometheus scraping.
• Import a sample dashboard to Grafana
• Enjoy!
