System Watchdog

System watchdog for your machine. Detect real, actionable anomalies and stay quiet about normal steady-state conditions. Auto-detects Linux vs macOS.

Goal

Optimize for few, high-signal alerts.

Do not alert on:

• process age alone (long-running is not "stale")
• Docker/container/virtualization baseline memory usage
• absolute disk-used GB unless near a real limit
• generic top-process lists without an actual anomaly

Do alert on:

• memory pressure that is worsening (swap growth, low available memory, macOS compressor pressure)
• runaway process growth (memory leak signals via delta tracking)
• sustained abnormal CPU burn (>2 cores for >15 min)
• disk pressure near a practical limit (>90% or <20 GB free)
