Labels in Grafana alerting

This topic explains why labels are a fundamental component of alerting.

• The complete set of labels for an alert is what uniquely identifies an alert within Grafana alerts.
• The Alertmanager uses labels to match alerts for [silences]({{< relref "../../silences/_index.md" >}}) and [alert groups]({{< relref "../../alert-groups/_index.md" >}}) in [notification policies]({{< relref "../../notifications/_index.md" >}}).
• The alerting UI shows labels for every alert instance generated during evaluation of that rule.
• Contact points can access labels to dynamically generate notifications that contain information specific to the alert that is resulting in a notification.
• Labels can be added to an [alerting rule]({{< relref "../../alerting-rules/_index.md" >}}). These manually configured labels are able to use template functions and reference other labels. Labels added to an alerting rule take precedence in the event of a collision between labels.
