What Argus Disk is

Argus Disk is a free SMART monitoring daemon for Linux homelab systems. It collects disk attributes every six hours and keeps a rolling 180-day history, then uses linear regression to estimate when an attribute may reach its critical threshold. Its maker says the thresholds use Backblaze failure data rather than vendor defaults. Temperature anomaly detection uses z-scores and requires 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 for 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 network. It requires a Linux host, Python 3.10 or later, and smartmontools; ntfy and Prometheus with Grafana are optional. It is distributed under the MIT License.

Who it suits

Argus Disk suits Linux homelab administrators who want disk health history and failure warnings on their own hardware.

What it does well

Forecasts critical thresholds using linear regression
Optional ntfy alerts and Prometheus metrics
MIT License permits use, modification, and distribution

What to know first

Requires Linux, Python 3.10+, and smartmontools

Getting started

Open the Argus Disk project website.
Use a Linux host with Python 3.10 or later and smartmontools installed.
Run the install script and configure the disks.
Add ntfy or Prometheus with Grafana if you want those optional integrations.

Verdict

Argus Disk combines historical SMART monitoring, threshold forecasts, and optional alerts or dashboard metrics. Its listed system requirements make it a fit for Linux homelab setups rather than other platforms.
