Grafana sends alert notifications to Warrn via a webhook contact point. When an alert fires in Grafana, Warrn creates an alert. When it resolves in Grafana, Warrn auto-resolves the matching alert.

​
Setup

1

Add the integration in Warrn

Open a service or team in Warrn. Go to the Integrations tab, add Grafana, and copy the generated webhook URL.
2

Create a contact point in Grafana

In Grafana, go to Alerting > Contact Points. Click Add contact point, select Webhook as the type, and paste the webhook URL from Warrn.
3

Assign to a notification policy

In Grafana, go to Alerting > Notification Policies. Assign your new contact point to the alert rules you want routed to Warrn.

​
How it works

Grafana sends a JSON payload containing an array of alerts. Each alert has a status field (firing or resolved).
  • Firing alerts create a new alert in Warrn. If a matching alert already exists (same fingerprint), it increments the occurrence count instead.
  • Resolved alerts auto-resolve the matching Warrn alert by fingerprint.

Severity mapping

Warrn maps the severity label from your Grafana alert rules:
Add a severity label to your Grafana alert rules for accurate mapping. Without it, all alerts default to medium.
