Alerts¶
Configurable notifications when container metrics exceed thresholds.
Alert Types¶
| Type | Triggers On |
|---|---|
| CPU | CPU exceeds threshold for duration |
| Memory | Memory exceeds threshold |
| Disk | Disk exceeds threshold |
| Container State | Container stops/unhealthy/restarting |
| Restart Count | Restarts exceed N in window |
Creating Alert Rules¶
- Navigate to Health > Alerts
- Click Create Alert
- Select type, container, threshold, duration, severity
- Choose notification channels
- Click Save
The form adapts based on alert type — CPU/Memory/Disk show threshold/duration; Container State shows state selector; Restart Count shows count/window fields.
Cooldown¶
Default 15-minute cooldown per alert type + severity + container combination. Prevents notification spam during sustained issues.
Notification Channels¶
| Channel | Format |
|---|---|
| HTML with severity-colored header | |
| Slack | Block Kit structured message |
| Webhook | JSON payload |
Configure channels in Admin > Settings > Notifications.
