GSmartControl inspects the health of hard drives and SSDs using SMART information.
Scrutiny
Scrutiny monitors hard drive SMART data, historical trends, and failure thresholds.

About Scrutiny
Scrutiny is an open source hard drive health monitoring and dashboard tool designed to complement the existing smartd S.M.A.R.T daemon. It addresses key limitations of smartd, including its lack of differentiation between critical and informational S.M.A.R.T attributes, absence of historical metric tracking, reliance on generic manufacturer-set failure thresholds, and command-line only interface that is poorly suited for headless server environments.
The tool provides a web-based dashboard focused on critical drive health metrics, automatically detects all connected hard drives, and tracks S.M.A.R.T attribute trends over time. It uses real-world drive failure rates to set customized, more actionable alert thresholds, and includes temperature tracking and configurable webhook notifications for alerts. Scrutiny is distributed as an all-in-one Docker image, with manual installation also supported.
