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.

TagNames	string	No	The reserved parameter.	None
Start	string	Yes	The beginning of the time range to query. Set this parameter to a UNIX timestamp representing the number of milliseconds that have elapsed since January 1, 1970, 00:00:00 UTC. Note You can specify a start time up to two months earlier than the current time.	1642435200000
End	string	Yes	The end of the time range to query. Set this parameter to a UNIX timestamp representing the number of milliseconds that have elapsed since January 1, 1970, 00:00:00 UTC. Note The end time must be later than the start time, but not later than 00:00:00 (UTC+8) on the current day.	1643040000000
Region	string	No	The region in which the instance resides. Valid values: cn-china: Chinese mainland. cn-hongkong: China (Hong Kong). ap-southeast-1: Singapore. This parameter takes effect only if InstanceIds is left empty. If you leave InstanceIds empty, the system obtains data from the region specified by Region. By default, Region is set to cn-china. If you specify InstanceIds, Region does not take effect and the system obtains data from the region in which the first specified instance resides.** Note If your instances reside in the regions inside the Chinese mainland, set this parameter to cn-china**.	cn-china
