Alerts & Notifications

Configure alert rules and notification channels in Sysmos.

Sysmos provides a flexible alerting system with multiple notification channels, intelligent cooldown, and deduplication to prevent alert fatigue.

Alert Rules

Each API monitor can have multiple alert rules:

Availability Alerts

  • Trigger when a monitor reports down from one or more regions
  • Configure how many consecutive failures before alerting
  • Set up auto-resolve when the monitor recovers

Performance Alerts

  • Trigger when response time exceeds a threshold (e.g., > 2000ms)
  • Use rolling averages to avoid alerting on single spikes

SSL Certificate Alerts

  • Alert when an SSL certificate is expiring within a configurable window (e.g., 14 days)

Cooldown & Deduplication

To prevent alert storms:

  • Cooldown period — After an alert fires, suppress repeat alerts for the same condition for a configurable duration (default: 5 minutes)
  • Deduplication — If the same alert condition is already active, new occurrences are grouped rather than sent as separate notifications
  • Recovery notifications — Optionally receive an "all clear" when the issue resolves

Alert History

All alerts are logged with:

  • Timestamp
  • Monitor and region that triggered it
  • Alert condition details
  • Notification channels that were contacted
  • Resolution timestamp (if resolved)

View the full history in AlertsHistory in the dashboard.
