Query snapshot size monitoring data by using DescribeSnapshotMonitorData - Elastic Compute Service - Alibaba Cloud - Elastic Compute Service

Operation description

When you call this operation, take note of the following items:

A maximum of 400 data entries can be returned at a time. The condition (EndTime – StartTime) / Period must be less than or equal to 400. In other words, the response parameter TotalCount cannot exceed 400. Otherwise, the InvalidParameter.TooManyDataQueried error is returned.
You can query monitoring data only within the last 30 days. The StartTime parameter cannot be more than 30 days earlier than the current time.

Test

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.
