Prometheus, Grafana, and Alertmanager

This page describes the legacy CDM implementation, which will be deprecated in an upcoming release. We strongly recommend that you transition to the current CDM implementation as soon as possible.

Use Prometheus, Grafana, and Alertmanager when you deploy the CDM.

After you’ve finished deploying the CDM, you can use the CDM as a sandbox to explore deployment with a different monitoring and alerting framework.

Remember, the CDM is a reference implementation and not for production use. When you create a project plan, you’ll need to determine how to monitor and send alerts in your production deployment.

To deploy Prometheus, Grafana, and Alertmanager:

  1. Deploy Prometheus, Grafana, and Alertmanager in your cluster:

    $ /path/to/forgeops/bin/prometheus-deploy.sh
    
    This script requires Helm version 3.04 or later due to changes in the behaviour of 'helm repo add' command.
