Alarms
Alarm System
Monitor telemetry and trigger alerts when conditions are met
The alarm system monitors telemetry data in real-time and triggers alerts when conditions are met.
Components
- Alarm Rules — Define what conditions trigger an alarm (e.g., temperature > 40°C)
- Alarm Instances — Individual occurrences of triggered alarms
- Actions — What happens when an alarm triggers (notification, webhook, email)
Alarm Flow
- Telemetry data arrives from a device
- The alarm evaluator checks all enabled rules for the device's application
- If a condition is met:
- Check the cooldown period to prevent re-triggering
- Create an Alarm Instance with status ACTIVE
- Execute configured actions (notification, webhook, email)
- Users can Acknowledge and Resolve alarm instances
Severity Levels
| Severity | Use Case |
|---|---|
| INFO | Informational alerts that don't require immediate action |
| WARNING | Values approaching a limit — attention needed soon |
| CRITICAL | Values requiring immediate action |
