remetric

Re-metric your stack - find waste in Prometheus, Grafana & Loki.

remetric is a read-only doctor for self-hosted observability stacks. Point it at a Prometheus server (optionally a Grafana too) and it returns a ranked, actionable list of cardinality problems, unused metrics, label-pattern anti-patterns, and alert-hygiene findings - each with a paste-ready fix.

What it finds

• Hot labels - cardinality explosions driven by a single label.
• Unused metrics - metrics scraped but never referenced by any dashboard or rule.
• Overly granular label patterns - labels that look like unbounded identifiers.
• Never-firing alerts - rules whose threshold has not triggered over the lookback window.
• Always-firing alerts - rules whose threshold is permanently met (likely broken).
