Smart Alert System

Get notified when it matters — before problems become outages.

How Alert Rules Work

Define thresholds for any metric — CPU, memory, disk, load, or device-specific values. A background cron job evaluates every rule on a regular cycle, transitioning alerts through states: OK, warning, critical, and firing.

  • Threshold-based rules for any metric
  • Cron-based evaluation cycle
  • Alert states: OK, warning, critical, firing
  • Automatic state transitions
Alert Lifecycle OK WARN CRIT FIRE Rule: CPU > 90% for 5 min Current: 94.2% (3m above threshold) Status: WARNING → evaluating...

Alert Types

Server Scout covers all the critical failure modes — from server resource exhaustion to device-specific issues like switch ports going down or UPS batteries running low.

  • CPU, memory, disk, and load thresholds
  • Server offline detection
  • Service failure alerts (systemd)
  • Device alerts: port down, battery low, temperature high
✗ db-01: Disk /var at 96% ⚠ web-03: CPU at 91% (3m) ✗ sw-core: Port 23 DOWN ⚠ ups-01: Battery at 32%

Automatic Recovery Detection

When a metric returns to normal, Server Scout automatically resolves the alert and sends a recovery notification. No manual intervention needed — the full lifecycle from firing to recovered is handled for you.

  • Automatic resolution when metrics normalize
  • Recovery notifications sent to your team
  • Full alert history with timestamps
  • No stale alerts cluttering your dashboard
Alert Timeline 14:23 FIRING CPU at 94% on web-01 14:28 Notification sent Email to 2 recipients 14:35 RECOVERED CPU back to 42% Duration: 12 minutes

Configurable Thresholds

Every server and device can have its own threshold settings. Set global defaults, then override per-server where needed. A database server might tolerate 80% memory usage, while a web server should alert at 70%.

  • Per-server and per-device thresholds
  • Global defaults with local overrides
  • Separate warning and critical levels
  • Easy tuning from the dashboard UI
