Alerts notify you when a host metric exceeds a threshold you define. VordFleet supports email and webhook notifications.
Creating an Alert Rule
- Navigate to Alerts > Rules in the dashboard.
- Click Create Rule.
- Configure the rule:
- Name — A descriptive name (e.g., “High CPU Warning”)
- Metric — The metric to monitor (CPU, memory, disk, etc.)
- Condition — The threshold (e.g., “CPU usage > 90%“)
- Duration — How long the condition must persist before firing (e.g., “5 minutes”)
- Scope — Apply to a specific fleet, host, or all hosts
- Choose a notification method (email or webhook URL).
- Click Save.
Default Alert Rules
New fleets include these default rules:
- Disk space critical — Fires when any disk is over 95% full
- Host offline — Fires when a host stops reporting for 5 minutes
- Memory pressure — Fires when available memory drops below 5%
You can edit or disable default rules from the alert rules page.

Webhook Notifications
To send alerts to Slack, PagerDuty, or another service, use a webhook URL as the notification target. VordFleet sends a JSON payload with the alert details.
