Configuring alerts and notifications for user workload monitoring

You can configure a local or external Alertmanager instance to route alerts from Prometheus to endpoint receivers. You can also attach custom labels to all time series and alerts to add useful metadata information.

Configuring alert notifications

In {product-title}, an administrator can enable alert routing for user-defined projects with one of the following methods:

  • Use the default platform Alertmanager instance.

  • Use a separate Alertmanager instance only for user-defined projects.

Developers and other users with the alert-routing-edit cluster role can configure custom alert notifications for their user-defined projects by configuring alert receivers.

Note

Review the following limitations of alert routing for user-defined projects:

  • User-defined alert routing is scoped to the namespace in which the resource is defined. For example, a routing configuration in namespace ns1 only applies to PrometheusRules resources in the same namespace.

  • When a namespace is excluded from user-defined monitoring, AlertmanagerConfig resources in the namespace cease to be part of the Alertmanager configuration.
