Best Self-hosted Alternatives to DriveDx

Scrutiny is a self-hosted web application for monitoring disk health by collecting SMART data from smartd and correlating it with real-world failure rates. It auto-detects connected drives, tracks SMART metrics over time, and provides a focused dashboard with configurable alerts.

Key Features

• Web UI dashboard focused on critical SMART metrics
• Integration with smartd for data collection (no re-invention of SMART parsing)
• Auto-detection of all connected drives
• Historical SMART metric tracking and trend visualization
• Thresholds informed by real-world drive failure data
• Temperature monitoring
• Docker-based deployment with an omnibus image (web + collector) and options for manual install
• Configurable alerting/notifications via Webhooks and other channels
• Hub/Spoke deployment support (separate web, collector, and storage components)

Use Cases

• Centralized monitoring of multiple disks in servers, NAS, or data centers
• Proactive maintenance through alerts when SMART attributes change
• Long-term health trend analysis to inform replacement cycles or capacity planning

Limitations and Considerations

• Scrutiny is a work-in-progress and may have rough edges or incomplete features
• Requires privileged access to host devices to query SMART data (e.g., capability flags for containers)
• Some RAID controllers or USB-docked drives may require manual configuration to expose SMART data

Conclusion

Scrutiny provides a focused, self-contained solution for monitoring disk health via SMART data, with flexible deployment options and alerting to help mitigate data-loss risk.
