 You can use alert processing rules to add [action groups](./action-groups.md) or remove (suppress) action groups from your fired alerts. You can apply alert processing rules to different resource scopes, from a single resource, or to an entire subscription. You can also use them to apply various filters or have the rule work on a predefined schedule.

 Some common use cases for alert processing rules are described here.

+## Suppress notifications during planned maintenance
 
 Many customers set up a planned maintenance time for their resources, either on a one-time basis or on a regular schedule. The planned maintenance might cover a single resource, like a virtual machine, or multiple resources, like all virtual machines in a resource group. So, you might want to stop receiving alert notifications for those resources during the maintenance window.

 Most customers tend to define a few action groups that are used repeatedly in their alert rules. For example, they might want to call a specific action group whenever any high-severity alert is fired. As their number of alert rules grows, manually making sure that each alert rule has the right set of action groups is becoming harder.

 Azure Monitor alert rules let you select which action groups will be triggered when their alerts are fired. However, not all Azure alert sources let you specify action groups. Some examples of such alerts include [Azure Backup alerts](../../backup/backup-azure-monitoring-built-in-monitor.md), [VM Insights guest health alerts](../vm/vminsights-health-alerts.md), [Azure Stack Edge](../../databox-online/azure-stack-edge-gpu-manage-device-event-alert-notifications.md), and Azure Stack Hub.
