What's New

Prometheus rules as a usage source: Metrics and labels used in Prometheus alerting and recording rules now count as used.
Template variables as a usage source:. Metrics and labels used in label_values(...) and query_result(...) variable queries now count as used.
Aggregation labels are detected: Labels used in aggregate clauses (by, without, on or group_left) now count as used.
metric_usage_prometheus_rule_count: – New metric and dashboard panel showing how many Prometheus rules were analysed.
Docker image: A Multi-arch (amd64/arm64) image at ghcr.io/parthivrmenon/metric_usage_exporter.

Breaking changes!

The project was renamed from sigprune-exporter to metric_usage_exporter. All metrics now use the metric_usage_ prefix. Any dashboard, alerts or recording rules using these metrics must be updated.

Default port is now 10062 (was 8080), registered on the Prometheus default portallocations wiki. Update scrape targets, or run with -listen-address :8080 to keep the old port.
Binaries are now named metric_usage_exporter-<os>-<arch>, and the dashboard file ismetric_usage.json. Re-import the dashboard: the old one queries sigprune_* metrics.
The repository moved to parthivrmenon/metric_usage_exporter. Old links will automatically redirect.
