What are Scrutiny and smartctl Exporter?
Scrutiny
Scrutiny is a web application that collects SMART data from hard drives across your machines and presents disk health, temperature, and failure predictions in a unified dashboard. It helps catch failing drives early.
- SMART data collection
- Failure prediction
- Temperature history
- Notification support
smartctl Exporter
smartctl_exporter collects SMART attributes from disks via smartmontools and exposes them as Prometheus metrics. It enables proactive alerting on impending drive failures.
- Disk SMART metrics
- Failure prediction data
- Prometheus compatible
- Low overhead
