smartctl_exporter review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

smartctl_exporter is open-source software that runs smartmontools and exposes storage-device health and telemetry as Prometheus metrics. It is designed for infrastructure teams monitoring disks, SSDs, and NVMe devices across Linux, Windows, macOS, and FreeBSD environments. The exporter can automatically scan available devices or monitor explicitly configured devices with repeatable device flags. Its output covers device metadata, SMART attributes, status, error logs, self-test logs, temperature, power-on time, capacity, read/write statistics, and NVMe endurance indicators.

Its strongest fit is a Prometheus-centered monitoring stack. Device include and exclude regular-expression filters help control discovery, while configurable SMART polling and device-rescan intervals provide control over collection behavior. The project integrates with Prometheus and smartmontools, and it can run directly or through a provided Docker image and Docker Compose example. TLS and basic authentication are available for the metrics web endpoint, giving operators options for protecting access to the exporter’s endpoint.

The main trade-off is its focused scope. smartctl_exporter exposes measurements and SMART status, but the broader monitoring experience depends on Prometheus, and temperature alerts require Prometheus-side alert rules. Teams already operating Prometheus and seeking detailed storage telemetry should find the feature set well aligned with that workflow. Teams seeking a standalone disk-health interface or built-in alerting engine should consider a product designed around those functions instead. The published release page lists version 0.14.0 dated 2025-04-22.

smartctl_exporter pros and cons

• Where it wins
  • Exports SMART, temperature, error, self-test, and endurance metrics
  • Filters devices and controls polling and rescan intervals
  • Supports TLS, basic authentication, Docker, and Docker Compose
• Where it doesn't
  • Requires Prometheus for the broader monitoring experience
  • Temperature alerts require Prometheus-side alert rules
  • Requires smartmontools 7.0 or newer
