Operation description

API Guide

After you execute a command, it does not necessarily mean that the command was successfully executed or produced the expected effect. You must use this API to check the actual execution results, and the actual output takes precedence.
You can query execution information from the last four weeks, with a maximum retention limit of 100,000 records.
You can obtain job results through management event subscription for Cloud Assistant task status, which avoids frequent polling and improves efficiency.
When performing a paged query on the home page, you only need to set MaxResults to limit the number of returned entries. The NextToken in the return result serves as the credential for querying subsequent pages. When querying subsequent pages, set the NextToken parameter to the NextToken value obtained from the previous response as the query credential, and set MaxResults to limit the number of returned entries.
Differences between DescribeInvocations and DescribeInvocationResults:
- When a single RunCommand/InvokeCommand invocation targets multiple instances:
  - DescribeInvocations provides the execution status on each instance and an aggregation status across all instances.
  - DescribeInvocationResults only provides individual execution statuses per instance, without aggregated multi-instance status.
- When a single RunCommand/InvokeCommand invocation targets one instance:
  - There is little difference between DescribeInvocations and DescribeInvocationResults, and they can fully replace each other.
- When you need to view the execution history of scheduled (periodic) tasks or automatic startup tasks (RepeatMode=Period, EveryReboot), only DescribeInvocationResults can retrieve historical execution records (by specifying IncludeHistory=true). In contrast, DescribeInvocations only returns the latest task status.
- When you need to view the command content or parameters, only DescribeInvocations returns CommandContent.

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.
