CreateNotificationConfiguration - Auto Scaling - Alibaba Cloud Documentation Center

Creates a notification rule. You can call the CreateNotificationConfiguration operation to create a notification rule to stay informed about scaling events or resource changes. This helps you learn about the dynamic status of your scaling group in real time and further automates the management of scaling events.

Usage notes

You can configure CloudMonitor system events, Message Service (MNS) queues, or MNS topics to receive notifications. When a specified type of scaling activity or resource change occurs in a scaling group, Auto Scaling notifies CloudMonitor or MNS.
You cannot specify the same recipient service 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 MNS resource, such as the same MNS 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.
