Argus Disk
What it is
Argus Disk is a free SMART monitoring daemon for Linux homelab systems. It collects SMART attributes every six hours and keeps a rolling 180-day history. Linear regression uses that history to forecast when an attribute may reach its critical threshold, while the maker says its thresholds are calibrated with Backblaze failure data rather than vendor defaults. Temperature anomaly detection uses z-scores, requiring a score of at least 2.0 over 10 or more samples. Optional ntfy integration can send status-change alerts with priority routing. An optional Prometheus exporter exposes disk health, status, temperature, sector counts, forecasts, and overall status metrics for dashboards such as Grafana. Argus also supports JMicron JMB576 pass-through for multi-bay DAS enclosures, including TerraMaster D5-300 and similar devices. The maker says the software runs on the user's hardware without cloud use and keeps data within the user's network. It requires a Linux host, Python 3.10 or later, and smartmontools; ntfy and Prometheus with Grafana are optional. Argus is distributed under the MIT License.
For and against
For
- Collects SMART attributes every six hours
- Maintains a rolling 180-day history
- Forecasts critical thresholds using linear regression
- Optional ntfy alerts support priority routing
- Runs without cloud use, according to its maker
Against
- Requires a Linux host
- Requires Python 3.10 or later
- Requires smartmontools
The verdict
Argus Disk provides local SMART monitoring, trend forecasts, and optional alerting and metrics integrations. It requires a Linux host, Python 3.10 or later, and smartmontools.
Who it suits
Argus Disk suits Linux homelab users who want SMART history and disk-failure warnings on their own hardware. Its optional notification and Prometheus integrations may suit users who want alerts or dashboard metrics.
