promcheck

Finds Prometheus recording and alerting rules that silently reference missing metrics or wrong labels.

Pluginfreeglobal

promcheck is a free, open-source tool that identifies Prometheus recording and alerting rules referencing missing metrics or wrong labels, catching silent failures caused by exporter changes or human error. It runs as a CLI tool, in CI/CD with a strict exit-code mode, or continuously as its own Prometheus exporter. It's aimed at DevOps and SRE teams who want to catch broken Prometheus rules before they fail silently during an incident.
