Scrutiny is a free, self-hosted dashboard for monitoring hard drive health through S.M.A.R.T. metrics. It tracks metric history and temperature, with thresholds that can be customized based on real-world failure rates. Its collector uses smartctl to discover connected drives, and Scrutiny integrates with smartd. Failure alerts can be sent through email, webhooks, Discord, Gotify, Mattermost, ntfy, Slack, Teams, Telegram and other listed services. Users can deploy an all-in-one Docker image, separate hub-and-spoke Docker components or install it manually. The hub-and-spoke setup stores S.M.A.R.T. data in InfluxDB 2.8. The repository lists Linux, macOS and Windows binaries, but Windows Docker support remains in progress. Docker configuration requires passing drive devices through and granting SYS_RAWIO; NVMe drives may also need SYS_ADMIN. Some RAID controllers do not expose underlying SMART data to smartctl. The project describes itself as a work in progress with rough edges and lists the MIT license.
Who it is for
Scrutiny suits people who want to self-host drive-health monitoring and configure alerts. It may fit users comfortable with its deployment and hardware-permission requirements.
What is good
- Free and MIT licensed
- Tracks S.M.A.R.T. history and temperature
- Supports customizable failure thresholds
- Offers multiple alert destinations
What to know first
- Docker requires drive passthrough and SYS_RAWIO
- NVMe drives may also require SYS_ADMIN
- Some RAID controllers do not expose SMART data
- Project notes it has rough edges
Verdict
Scrutiny provides self-hosted S.M.A.R.T. monitoring with several deployment and alerting options. Check hardware compatibility and permission requirements before choosing a deployment method.
