Alertmanager

Grafana Cloud Alerting allows you to edit and view configuration for your Alertmanager directly inside of Grafana. See the official Alertmanager documentation to learn how to configure.

Note: Only organization Admins can view or update Alertmanger configurations.

Edit a config for Grafana Cloud Alerting

  1. In Grafana, hover your cursor over the Grafana Cloud Alerting icon and then click Alertmanager.
  2. If you have more than one Alertmanager source, there will be a dropdown at the top for you to select the data source to edit configurations.
  3. Currently active configuration for the Alertmanager will be displayed. Click the Edit button to enter edit mode and start making changes. Click “Save and finish editing” once done to persist your changes.
  4. Alternatively, updates to the Alertmanager configurations made using the cortextool will also sync and appear here.

Use the Grafana Labs-supplied SMTP option to configure email notifications

Grafana Cloud users who do not have an SMTP server available for sending alert emails may use Grafana-Labs supplied SMTP relay (available at smtprelay:2525).

  1. In Grafana, hover your cursor over the Grafana Cloud Alerting icon and then click Alertmanager.
  2. If you have more than one Alertmanager source, there will be a dropdown at the top for you to select the data source to edit configurations.
  3. Find info box with heading Send alert email notifications from Grafana Cloud at the top
  4. Enter desired email address into the email address field
  5. Click Update configuration button. Alertmanager config will be updated with grafana SMTP relay settings and an “email” receiver that will send to the specified email address.

Note: Following these steps will overwrite any custom global SMTP settings that you might have. Default route configuration will send all notifications to the “email” receiver. If you have already customized routes, they will not be updated and you will have to configure “email” receiver on the appropriate route.
