smartctl_exporter

What smartctl_exporter is

smartctl_exporter exports smartctl statistics to Prometheus for SMART monitoring. It reads JSON output from smartctl and requires smartmontools version 7.0 or later. When no devices are specified, it scans the system for available devices and can rescan as devices appear or disappear. The default metrics path is /metrics and the default listening port is 9633. TLS and basic authentication are supported through a web configuration file, and Linux deployments can use systemd socket activation instead of port listeners. The README includes a Docker Compose example using the project image in privileged mode as root. Device access may require smartctl to run as root, including for SATA access. The repository identifies the license as Apache-2.0 and directs security reports to the Prometheus security policy. Version 0.15.0, dated 2026-09-01, lists additional temperature values, endurance and verify-error metrics, and support for NVMe devices behind bridges. The project describes its platform as Linux and self-hosted.
