The application group feature allows you to manage resources from different services and regions by group. You can create application groups based on your business requirements and add your cloud resources such as servers and databases to application groups. You can manage alert rules by application group.

Background information

The application group feature is applicable to the following scenarios:
  • Manage resources from the business perspective

    You can add resources in your account to different application groups based on the business type. You can then query monitoring data and alerts from the business perspective.

  • Perform routine inspection and detect faults

    After you create application groups, you can use features such as group health check, faulty instance list, and dashboard to monitor the resources in the application groups. You can inspect resource usage in application groups on a routine basis, locate faulty resources, and identify causes at the earliest opportunity if you receive alert notifications.

  • Improve resource usage

    Application groups allow you to aggregate and display monitoring data from multiple dimensions. You can query monitoring data of an application group or a single instance to identify frequently accessed resources.
