Health score?A 0-100 score computed nightly from four factors: maintained (40%: recent commits and steady activity), popular (25%: GitHub stars, log scale), easy to install (20%: platforms, install notes, setup guides, Docker image) and light to run (15%: minimum RAM, ARM support). When the source code has been checked, a fifth factor, security check (20%: automated scan for committed secrets, unsafe desktop-app settings, known-vulnerable dependencies and project hygiene; any serious finding caps it at 20), is added. Factors without data are left out and the rest are rescaled.

Common questions

What smartctl output does smartctl_exporter use?

It uses the JSON output from smartctl to provide the data to Prometheus.

If the metrics look wrong, where should I check first?

Check the smartctl JSON output first to determine whether the issue should be reported to smartmontools or to the exporter repo.

What do I need to configure in Docker to reach disks on a host or Proxmox?

Set up SSH in smartctl.yml so the exporter can connect to the host devices.

Has the smartctl-exporter snap moved to Canonical?

Yes, the snap was transferred to Canonical ownership.
