Scrutiny
Scrutiny is a free, self-hosted dashboard for monitoring hard drive health through S.M.A.R.T. metrics. It records metric history and temperature, and allows customized thresholds based on real-world failure rates. Its collector uses smartctl to discover connected drives, and the project integrates with smartd. Failure notifications can be sent through email, webhooks, Discord, Gotify, Mattermost, ntfy, Slack, Teams, Telegram, and other listed services. Deployment choices include an all-in-one Docker image, separate hub-and-spoke Docker components, and manual installation; the hub-and-spoke setup stores S.M.A.R.T. data in InfluxDB 2.8. The repository lists Linux, macOS, and Windows binaries, while Windows Docker support remains in progress. For Docker, users must pass drive devices through and grant SYS_RAWIO; NVMe drives may also require SYS_ADMIN. Some RAID controllers do not pass underlying SMART data to smartctl. Manual installation instructions describe running the collector as an unprivileged user with restricted systemd permissions and network access. The project describes itself as a work in progress with rough edges and lists the MIT license.
