Error / Incident

This usually comes in the form of an alert in alertmanager.

There you will get which project (tools, toolsbeta, ...) is the one it's failing for.

Prometheus k8s cert expired

We don't have yet a way to autorefresh the certs prometheus uses to authenticate against k8s, so they need renewal. When they expire prometheus is not able to get metrics from it (so any k8s related metric will just not be there).

If that's the case, you can follow this guide.
