You can create scaling groups in Auto Scaling and use these scaling groups to automatically create instances with specific tags. Then, you can configure application group rules in Cloud Monitor based on the tags. This way, the instances are automatically added to different application groups based on the rules. This facilitates centralized operations and maintenance (O&M) of the instances. This strategy has the following characteristics: automatic addition of instances to an application group, high availability of auto scaling, and automated O&M.

Background information

  • Cloud Monitor can automatically group the resources of the following Alibaba Cloud services: Elastic Compute Service (ECS), ApsaraDB RDS, and Server Load Balancer (SLB). For ECS, only instances can be grouped. Other resources, such as NICs and disks, are not supported.
  • In this topic, an ECS instance that is automatically created in a scaling group is used. The tag team:dev is added to the ECS instance.

Step 1: Create an ECS instance to which a tag is added in Auto Scaling

  1. Log on to the Auto Scaling console.
  2. Create a scaling group. For more information, see Create a scaling group.
    Specify Multi-zone Scaling Policy to achieve high-availability auto scaling based on your business requirements.
  3. Create a scaling configuration, create an ECS instance, and then add the team:dev tag to the ECS instance. For more information, see Create a scaling configuration.
    Configure a scaling group
  4. On the Scaling Groups page, find the scaling group that you created and click its name. On the page that appears, click the Instances tab. On the Instances tab, view the ECS instance that is automatically created in the scaling group.

Step 2: Create an application group in the Cloud Monitor console

  1. Log on to the Cloud Monitor console.
  2. Create an application group. For more information, see Create an application group.
    You must specify Creation Method and Match Rule based on the following instructions:
    • Creation Method: Select Smart tag synchronization creation.1
    • Match Rule: set Resource Tag Key to team and specify Tag Value based on your business requirements. In this example, a tag value range of Contain dev is specified.Match Rule
  3. On the Application grouping tab of the Application Groups page, select Resource tags and enter tag key team in the search bar to search for the application group that you created.

  4. Click the name of your application group and view the resources in the group.
    The ECS instance that is automatically created in the scaling group is automatically added to the application group.1

    You can also view the monitoring data of the ECS instance. For more information, see Overview.
