 Grafana allows you to create alerting rules for an external Grafana Mimir or Loki instance that has ruler API enabled. For information on Grafana Alerting, see [About Grafana Alerting]({{< relref "../../alerting" >}}) which explains the various components of Grafana Alerting. We also recommend that you familiarize yourself with some of the [fundamental concepts]({{< relref "../fundamentals" >}}) of Grafana Alerting.

-Choosing how, when, and where to send your alert notifications is an important part of setting up your alerting system. These decisions will have a direct impact on your ability to resolve issues quickly and not miss anything important.
-
-As a first step, define your contact points; where to send your alert notifications to. A contact point is a set of one or more integrations that are used to deliver notifications. Add notification templates to contact points for reuse and consistent messaging in your notifications.
-
-Next, create a notification policy which is a set of rules for where, when and how your alerts are routed to contact points. In a notification policy, you define where to send your alert notifications by choosing one of the contact points you created. Add mute timings to your notification policy. A mute timing is a recurring interval of time during which you don’t want any notifications to be sent out.
-
-You can also add silences to stop notifications from one or more alert rules. The difference between a silence and a mute timing is that a silence only lasts for a specified window of time.
-
-When an alert rule fires, the ruler sends alert instances to the Alertmanager; one alert rule can trigger multiple individual alert instances.
-
-The Alertmanager receives these alert instances and then handles silences, groups alerts, and sends notifications to your contact points as defined in the notification policy.
