DescribeCloudAssistantStatus-阿里云帮助中心

Queries whether Cloud Assistant Agent is installed on one or more instances. If Cloud Assistant is installed, this operation also queries the total number of executed Cloud Assistant commands, the number of commands being executed, and the time when the last command was executed.

Operation description

Call this operation to query the Cloud Assistant status of instances before executing commands or sending files, especially for newly purchased instances. Execute commands or send files only when CloudAssistantStatus is true.
When paged query the first page, specify only MaxResults to limit the number of returned entries. The NextToken value in the response is used as the token to query the next page. When paged query the next page, set the NextToken parameter to the NextToken value obtained from the previous response and specify MaxResults to limit the number of returned entries.

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.
