Forward alerts from Grafana to a Matrix chat room.

This project provides a simple way to forward alerts generated by Grafana to a Matrix chat room.

Define a Grafana webhook alert channel that targets an instance of this application. This tool will convert the incoming webhook to a Matrix message and send it on to a specific chat room.

• 📦 Portable
  • As a single binary the tool is easy to run in any environment
• 📎 Simple
  • No config files, all required parameters provided on startup
• 🪁 Flexible
  • Support multiple grafana alert channels to multiple matrix rooms
• 📈 Monitorable
  • Export metrics to track successful and failed forwards

This applies to unified alerts, check the documentation for legacy alerts

Step 1

Run the forwarder by providing a matrix account to send messages from.

$ ./grafana-matrix-forwarder --user @userId:matrix.org --password xxx --homeserver matrix.org

Step 2

Add a new Contact Point in Grafana with the POST webhook type. Use the following URL:

http://<ip address>:6000/api/v1/unified?roomId=<roomId>

Replace with the server ID and matrix room ID.

Step 3

Add a new Notification Policy in Grafana to send alerts to the new contact point.

If you use the root policy, all alerts will be sent to that contact point

Step 4

Create alert rules in grafana and add text to the a "Summary" field to be displayed in the Matrix message.
