### How are labels used?
- 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/" >}}) and [alert groups]({{< relref "../alert-groups/" >}}) in [notification policies]({{< relref "../notification-policies/" >}}).
- The Alertmanager uses labels to match alerts for [silences]({{< relref "../silences/" >}}) and [alert groups]({{< relref "../alert-groups/" >}}) in [notification policies]({{< relref "../notifications/_index.md" >}}).
- The alerting UI displays labels for every alert instance generated by the 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/" >}}). These manually configured labels are able to use template functions and reference other labels. Labels added to an alerting rule here take precedence in the event of a collision between labels.
Notification policies determine how alerts are routed to contact points. Policies have a tree structure, where each policy can have one or more child policies. Each policy, except for the root policy, can also match specific alert labels. Each alert is evaluated by the root policy and subsequently by each child policy. If you enable the `Continue matching subsequent sibling nodes` option is enabled for a specific policy, then evaluation continues even after one or more matches. A parent policy’s configuration settings and contact point information govern the behavior of an alert that does not match any of the child policies. A root policy governs any alert that does not match a specific policy.
You can configure Grafana managed notification policies as well as notification policies for an [external Alertmanager data source]({{< relref "../../datasources/alertmanager.md" >}}). For more information, see [Alertmanager]({{< relref "./fundamentals/alertmanager.md" >}}).
