CreateNotificationConfiguration - Auto Scaling - Alibaba Cloud Documentation Center

Modifies event notification rules. Event notification rules support automatic sending of notifications to CloudMonitor, Simple Message Queue (SMQ, formerly MNS) topics, or SMQ queues when a specified type of events occur. This helps you understand the dynamics of your scaling group at the earliest opportunity and further automate resource management. If an existing event notification rule does not meet your business requirements, you can call the ModifyNotificationConfiguration operation to modify the event notification rule, without the need to create a new rule. Take not that you cannot modify the notification recipient of an event notification rule by calling this operation.

Usage notes

You can configure CloudMonitor system events, SMQ queues, or MNS topics to receive notifications. When a specified type of scaling event or resource change occurs in a scaling group, Auto Scaling notifies CloudMonitor or SMQ.
You cannot specify the same notification recipient for different event notification rules in a scaling group.
For example, if you create multiple event notification rules in a scaling group, the event notification rules cannot share the same CloudMonitor or SMQ resource, such as the same SMQ topic or queue.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

Request parameters

Parameter	Type	Required	Example	Description
Action	String	Yes	CreateNotificationConfiguration	The operation that you want to perform. Set the value to CreateNotificationConfiguration.
ScalingGroupId	String	Yes	asg-bp1igpak5ft1flyp****	The ID of the scaling group.
NotificationArn	String	Yes	acs:mns:cn-beijing:161456884340**:queue/modifyLifecycleHo**	The Alibaba Cloud Resource Name (ARN) of the notification recipient. The following list describes the value formats of this parameter: If you specify CloudMonitor as the notification recipient, specify the value in the `acs:ess:{region-id}:{account-id}:cloudmonitor` format. If you specify an SMQ queue as the notification recipient, specify the value in the `acs:mns:{region-id}:{account-id}:queue/{queuename}` format. If you specify an SMQ topic as the notification recipient, specify the value in the `acs:mns:{region-id}:{account-id}:topic/{topicname}` format. The variables in the preceding value formats have the following meanings: `region-id`: the region ID of the scaling group. `account-id`: the ID of the Alibaba Cloud account. `queuename`: the name of the SMQ queue. `topicname`: the name of the SMQ topic.
NotificationType.N	String	No	AUTOSCALING:SCALE_OUT_SUCCESS	The type of the notification rule N for scaling events or resource changes. Valid values of N: 1 to 8. Specify multiple values in the repeated list form. You can call the DescribeNotificationTypes operation to query the values of this parameter.
RegionId	String	No	cn-beijing	The region ID of the scaling group.
TimeZone	String	No	UTC+8	The time zone of notifications. Specify the value in UTC. For example, a value of UTC+8 specifies that the time is 8 hours ahead of Coordinated Universal Time, and a value of UTC-7 specifies that the time is 7 hours behind Coordinated Universal Time.
