How do you know if something bad is happening in your cluster? How do you know that a node is down, an application isn’t responding, or the storage backing a PVC has “disappeared”? If your answer to any of those is “when the users tell us there’s an error”, then it may be time to reevaluate your monitoring and alerting strategy.

Fortunately, OpenShift has built-in tools for doing just this. With only a small amount of work you can ensure that you’re receiving the proper alerts and warnings so that you can, hopefully, avoid any sticky situations. This week we are joined by Brian Gottfried, from Red Hat Consulting, to focus on Alertmanager, how to configure it and how to customize the settings to avoid both too many alerts and not enough.
