When your applications use more cloud products to meet the requirements of service resizing or technical architecture improvement, you need to modify the resources in your application groups.
When the O&M and development personnel of your applications are changed, you need to modify the alarm contact groups of your application groups.
- After resources are removed from an application group, the alarm rule configured for the application group is no longer applicable to the removed instances.
- After an instance is added to a group, the instance automatically gets associated with the alarm rule configured for the application group. You do not need to create an alarm rule for the instance.
Modify basic information
To modify the application group name or the contact group, go to the details page of the target application group. In the Basic Information area, click the pencil icon next to the group name or contact group information. Modify the name or the contact group and click OK.
Add or remove an instance
- To delete an instance, click the tab of the target product, find the target instance, and click Delete in the Actions column.
- To add an instance, click the tab of the target product and in the upper-right corner of the tab page, click Add Instance. On the displayed AddResource page, select the target instance and click Confirm.
Add a new product
Go to the details page of the target application group. Click Add Product. On the displayed AddResource page, select the target product and instance, and click Confirm.
