Do you validate your Prometheus and other observability-related rules? Sometimes, you want to check them thoroughly and reviewing their syntax is not enough. Here’s when this tool comes in handy.

Promruval (Prometheus Rule Validator) validates rules metadata and expression properties against your actual setup and requirements. To benefit from it, you’ll need to create a YAML configuration defining allowed values, limits, and other constraints and then invoke promruval validate in your CI pipeline. Some of the tool’s highlights are:

- Support for Prometheus, Thanos, Mimir, and Loki rules formats.
- Support for rule files in YAML and Jsonnet formats.
- A huge list of available validators, which cover rule groups, labels, PromQL & LogQL expressions, and more.
- An ability to have multiple configuration files.
