DescribeCloudAssistantStatus-阿里云帮助中心

Queries whether Cloud Assistant Agent is installed on instances. If Cloud Assistant Agent is installed, the system queries the total number of Cloud Assistant commands that have been run, the number of Cloud Assistant commands that are being run, and the time when Cloud Assistant commands were last run.

Operation description

Usage notes

Before you run commands on or send files to instances, especially new instances, we recommend that you query the status of Cloud Assistant on the instances by calling this operation and checking the return value of CloudAssistantStatus. Run commands on or send files to the instances only when the return value is true.
During a paged query, when you call the DescribeCloudAssistantStatus operation to retrieve the first page of results, set MaxResults to specify the maximum number of entries to return in the call. The return value of NextToken is a pagination token that can be used in the next call to retrieve a new page of results. When you call the DescribeCloudAssistantStatus operation to retrieve a new page of results, set NextToken to the NextToken value returned in the previous call and set MaxResults to specify the maximum number of entries to return in this call.

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.
