Create an application group - Application Groups| Alibaba Cloud Documentation Center

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. You can add servers, databases, or other resources that are related to the same business to an application group. You can also manage alert rules by application group.

Background information

The following table describes the methods that you can use to create application groups and the Alibaba Cloud services that are supported by each method.


Creation method	Description	Supported Alibaba Cloud service
Create an application group based on tags	If tags are attached to your instances, you can specify a tag-based matching rule to create an application group. All instances that match the rule are automatically added to the application group. If an existing instance has a tag that is specified in the matching rule, an application group is automatically created for the tag. If a new instance has a tag that is specified in the matching rule, the instance is automatically added to the application group. Up to 3,000 instances can match a rule at a time. For more information about how to create and attach tags in the Resource Management console, see Add a custom tag.

Manually create an application group	You can create a standard application group to manage existing instances based on your business requirements.	Supported cloud services
Create an application group based on instance names	You can create an application group by specifying a matching rule based on instance names. All instances that match the rule are automatically added to the application group.

Create an application group from a resource group	You can create an application group from a resource group that you configure. Then, you can add all instances in the resource group to the application group. For information about how to create a resource group in the Resource Management console, see Create a resource group.

Create an application group based on tags

Log on to the CloudMonitor console.
In the left-side navigation pane, click Application Groups.
On the Application Group tab, click the icon or Create Application Group.

In the Create Application Group panel, set the Creation Method parameter to Create Based on Tags, and then set the other parameters as needed. The following table describes the parameters.


Parameter	Description
Application Group Name	CloudMonitor automatically generates a name for the application group.
Region	The region where the application group resides.
Resource Tag Key	The tag key of the instance. To automatically add instances, you can specify a matching rule based on the tag key and the tag value of a resource.
Tag Value	The tag value of the instance. To automatically add instances, you can specify a matching rule based on the tag key and the tag value of a resource. Instances whose tag values contain, start with, end with, do not contain, or are equal to the value that you specify are automatically added to the application group. If you set the Tag Value parameter to All, all instances with the specified tag are added to the application group. A new instance that matches the rule is also added to the application group.
Initialize Agent Installation	After you turn on Initialize Agent Installation, CloudMonitor automatically installs the CloudMonitor agent on the instances in the application group to collect monitoring data from the instances. By default, Initialize Agent Installation is turned on.
Receive Event Notifications	After you turn on Receive Event Notifications, CloudMonitor automatically sends alert notifications when critical or warning events occur on the instances that are added to the application group. By default, Receive Event Notifications is turned on.
Alert Contact Group	The contact group to which alert notifications are sent. For information about how to create an alert contact group, see Create an alert contact group.
Alert Template	You can use an alert template to initialize the alert rules of the application group. For information about how to create an alert template, see Create an alert template.
