Spec score 7.9 #12 of 30 in Disk Health Monitoring Software

What it is

Argus Disk is a Linux SMART monitoring daemon for homelab systems. It gathers drive attributes every six hours and keeps a rolling 180-day history; linear regression uses that record to estimate when an attribute may reach its critical threshold. 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 makes disk health, status, temperature, sector counts, forecasts, and overall status available to dashboards such as Grafana. Argus supports JMicron JMB576 pass-through for multi-bay DAS enclosures, including TerraMaster D5-300 and similar devices. The maker says it 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 free and distributed under the MIT License.

Strong points and limits

Strong points

  • Free plan; MIT-licensed
  • Keeps a rolling 180-day SMART history
  • Forecasts critical thresholds with linear regression
  • Optional ntfy alerts and Prometheus metrics
  • Supports JMicron JMB576 multi-bay enclosures

Limits

  • Requires a Linux host
  • Requires Python 3.10+ and smartmontools
  • ntfy and Prometheus/Grafana are optional integrations

Who it suits

Argus suits Linux homelab operators who want drive-health history and failure warnings on their own hardware. Its listed requirements include a Linux host, Python 3.10+, and smartmontools.

Verdict

Argus combines historical SMART monitoring, threshold forecasts, and temperature anomaly detection for Linux homelabs. Its free plan avoids cloud use, but it requires a Linux host and the listed dependencies.
