Modify event notification rules using ModifyNotificationConfiguration - Auto Scaling - Alibaba Cloud - Auto Scaling

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.

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
