Lightning Talk: How We Validate User Initiated Config Changes in Promet...
summary
A small Go tool called PR checker runs on every pull request in a single large git repo, parses Prometheus rules with the Go Prometheus parser, and enforces checks for targets connectivity, number of metrics, and alert definitions. It posts human-readable comments and fails CI for disallowed errors (warnings don’t break the build), is extensible for new rules, and measurably increases rule quality as more teams onboard and fix alerts after the automated feedback.
