Alerts notify you when a host metric exceeds a threshold you define. VordFleet supports email and webhook notifications.
Creating an Alert Rule
Creating and customizing your own alert rules requires a Team plan. Alerting starts on Pro, which provisions the built-in default rules (listed below) with email and webhook delivery — you can enable or disable them but not create custom rules. The Free plan has no alert rules.
- Navigate to Settings > Alerts 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 — Assign the rule to one or more hosts
- Choose a notification method (email or webhook URL).
- Click Save.
Default Alert Rules
When you upgrade to Pro or Team, these eight built-in default rules are provisioned and applied to all of your hosts:
| Rule | Condition | Severity | Duration |
|---|---|---|---|
| Disk usage above 90% | Disk usage > 90% | Warning | 5 min |
| CPU usage above 90% | CPU usage > 90% | Warning | 5 min |
| Memory usage above 90% | Memory usage > 90% | Warning | 5 min |
| Machine offline | Host stops reporting | Critical | 1 min |
| Disk health issues | SMART reports a failing disk | Critical | 1 min |
| Failed services detected | One or more services failed | Warning | 1 min |
| Security updates available | Security updates pending | Info | 1 min |
| New SSH connection | A new SSH session is opened | Info | Immediate |
On the Pro plan these rules are read-only — you can enable or disable them, but not edit their thresholds. On the Team plan you can also create and customize your own rules and thresholds. The Free plan has no alert rules at all.
Alert Severities
| Severity | Use Case |
|---|---|
| Info | Informational, no action needed |
| Warning | Investigate when convenient |
| Critical | Requires immediate attention |
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.
