Add an external Alertmanager
Set up Grafana to use an external Alertmanager as a single Alertmanager to receive all of your alerts. This external Alertmanager can then be configured and administered from within Grafana itself.
Note
Grafana Alerting does not support sending alerts to the AWS Managed Service for Prometheus due to the lack of sigv4 support in Prometheus.
After you have added the Alertmanager, you can use the Grafana Alerting UI to manage silences, contact points, and notification policies. A drop-down option in these pages allows you to switch between alertmanagers.
External alertmanagers should now be configured as data sources using Grafana Configuration from the main Grafana navigation menu. This enables you to manage the contact points and notification policies of external alertmanagers from within Grafana and also encrypts HTTP basic authentication credentials.
To add an external Alertmanager, complete the following steps.
Click Connections in the left-side menu.
On the Connections page, search for
Alertmanager
.Click the Create a new data source button.
If you don’t see this button, you may need to install the plugin, relaunch your Cloud instance, and then repeat steps 1 and 2.
Fill out the fields on the page, as required.
If you are provisioning your data source, set the flag
handleGrafanaManagedAlerts
in thejsonData
field totrue
to send Grafana-managed alerts to this Alertmanager.Note: Prometheus, Grafana Mimir, and Cortex implementations of Alertmanager are supported. For Prometheus, contact points and notification policies are read-only in the Grafana Alerting UI.
Click Save & test.
