Auto Scaling:ModifyNotificationConfiguration

Last Updated:Jun 18, 2024

Modifies event notification rules. Event notification rules support automatic sending of notifications to CloudMonitor, Message Service (MNS) topics, or MNS queues when a specified type of events occur. This helps you learn about 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 method of an event notification rule by calling this operation.


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.
