Enable Image Alerts

8.2.1 Install Grafana Image Renderer

If you want pictures or graphs added to your regular notifications, you can install the Grafana Image Renderer. It can be installed via the built-in Grafana CLI:

sudo grafana-cli plugins install grafana-image-renderer

Afterward, restart Grafana for the dependency to show up:

sudo systemctl restart grafana-server

Check the status of the Grafana Server:

# Check status
systemctl status grafana-server

The output should look similar to this:

● grafana-server.service - Grafana instance

WARNING: The following section is still Work in Progress for Grafana 9, as windows and settings have changed in terms of names, behavior, and placement.

8.2.2 Apply Notification Settings

After Grafana is up and running again, go to the Grafana webpage.

  1. Click on the notification icon on the left menu bar.
  2. Move to the notification channels on the second tab.
  3. Open your node's notification channel.
  4. Activate image rendering by enabling Include Image.
  5. Click the Save button.

From now on, all notifications you've set up will automatically send graphs.

8.2.3 Enable Continuous Notifications

Within the notification dashboard of the node, you can also activate send reminders. Alert reminders are sent after notification rules are evaluated and a certain amount of time has passed.

By setting it to 1h, you will get a notification every hour if a critical error or status has not changed. Continuous notification behavior is helpful if you want regular node status reports.

8.2.4 Permanent Alerts

After enabling it on the notification dashboard, you could head over to your node's dashboard and clone or create a new notification. For it to show permanent notifications at a constant rate, you can set a metric so high that it is never supposed to be reached. For instance: If you want hourly updates on the participation rate, you can select the alert for under 100% participation. In this case, you would get a graph of the network participation once an hour.
