PrometheusRuleFailures¶
Meaning¶
Prometheus is failing rule evaluations. Prometheus rules are incorrect or failed to calculate.
Impact¶
Metrics and alerts may be missing or inaccurate.
Diagnosis¶
Your best starting point is the rules page of the Prometheus UI (:9090/rules). It will show the error.
You can also evaluate the rule expression yourself, using the UI, or maybe using PromLens to help debug expression issues.
Mitigation¶
Fix rules.
