Configuring an Alertmanager data source

Connect to an Alertmanager data source

Grafana includes built-in support for Prometheus Alertmanager. Once Grafana alerting is configured, you can use the Grafana alerting UI to manage silences, contact points as well as notification policies. A drop-down option in these pages allows you to switch between Grafana and any configured Alertmanager data sources.

Alertmanager implementations

Prometheus, Cortex, and Grafana Mimir implementations of Alertmanager are supported. You can specify implementation in the data source settings page. Prometheus contact points and notification policies are read-only in the Grafana alerting UI, as it does not support updating configuration via HTTP API.

Configuring an Alertmanager data source

You can configure an Alertmanager data source to use with Grafana alerting.

Prerequisites

To configure Alertmanager, you must have the following pre-requisite complete:

  • A Prometheus instance, with ingested metrics, and at least one alert or recording rule configured. You will need the URL for your workspace.

  • Permissions defined for Amazon Managed Grafana to have read access to your alerts, alert groups, silences, and contact points from your Alertmanager implementation.

To configure an Alertmanager data source

  1. From your Grafana console, in the Grafana menu, choose the Data source page under Configuration.

  2. Choose Add data source, and select Alertmanager from the list of data source types.

  3. Provide the following information for your new data source.

    • For Name, provide a name of your choosing for your data source.

    • For Implementation, choose your Alertmanager implementation – either Prometheus, Mimir, or Cortex.

    • Under HTTP, for URL, provide the Alertmanager URL. For Prometheus, this is the workspace URL, with alertmanager appended. For example, https://myprometheus/workspaces/ws-example-1234-5678-abcd-xyz00000001/alertmanager.

    • Under Auth, configure the authentication details needed to access your Alertmanager implementation.

  4. Choose Save & test to finish your data source setup.

    If your data source is set up correctly, you will see a message saying Health check passed.
