# GetCommandInvocation
<a name="API_GetCommandInvocation"></a>

Returns detailed information about command execution for an invocation or plugin. The Run Command API follows an eventual consistency model, due to the distributed nature of the system supporting the API. This means that the result of an API command you run that affects your resources might not be immediately visible to all subsequent commands you run. You should keep this in mind when you carry out an API command that immediately follows a previous API command.

 `GetCommandInvocation` only gives the execution status of a plugin in a document. To get the command execution status on a specific managed node, use [ListCommandInvocations](API_ListCommandInvocations.md). To get the command execution status across managed nodes, use [ListCommands](API_ListCommands.md).

## Request Parameters
<a name="API_GetCommandInvocation_RequestParameters"></a>

For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

The request accepts the following data in JSON format.

 ** [CommandId](#API_GetCommandInvocation_RequestSyntax) **   <a name="systemsmanager-GetCommandInvocation-request-CommandId"></a>
(Required) The parent command ID of the invocation plugin.  
Type: String  
Length Constraints: Fixed length of 36.  
Required: Yes

 ** [InstanceId](#API_GetCommandInvocation_RequestSyntax) **   <a name="systemsmanager-GetCommandInvocation-request-InstanceId"></a>
(Required) The ID of the managed node targeted by the command. A *managed node* can be an Amazon Elastic Compute Cloud (Amazon EC2) instance, edge device, and on-premises server or VM in your hybrid environment that is configured for AWS Systems Manager.  
Type: String  
Pattern: `(^i-(\w{8}|\w{17})$)|(^mi-\w{17}$)`   
Required: Yes

 ** [PluginName](#API_GetCommandInvocation_RequestSyntax) **   <a name="systemsmanager-GetCommandInvocation-request-PluginName"></a>
The name of the step for which you want detailed results. If the document contains only one step, you can omit the name and details for that step. If the document contains more than one step, you must specify the name of the step for which you want to view details. Be sure to specify the name of the step, not the name of a plugin like `aws:RunShellScript`.  
To find the `PluginName`, check the document content and find the name of the step you want details for. Alternatively, use [ListCommandInvocations](API_ListCommandInvocations.md) with the `CommandId` and `Details` parameters. The `PluginName` is the `Name` attribute of the `CommandPlugin` object in the `CommandPlugins` list.  
Type: String  
Length Constraints: Minimum length of 4.  
Required: No

Valid Values: `Pending | InProgress | Delayed | Success | Cancelled | TimedOut | Failed | Cancelling` 

 ** [StatusDetails](#API_GetCommandInvocation_ResponseSyntax) **   <a name="systemsmanager-GetCommandInvocation-response-StatusDetails"></a>
A detailed status of the command execution for an invocation. `StatusDetails` includes more information than `Status` because it includes states resulting from error and concurrency control parameters. `StatusDetails` can show different results than `Status`. For more information about these statuses, see [Understanding command statuses](https://docs.aws.amazon.com/systems-manager/latest/userguide/monitor-commands.html) in the * AWS Systems Manager User Guide*. `StatusDetails` can be one of the following values:  
+ Pending: The command hasn't been sent to the managed node.
+ In Progress: The command has been sent to the managed node but hasn't reached a terminal state.
+ Delayed: The system attempted to send the command to the target, but the target wasn't available. The managed node might not be available because of network issues, because the node was stopped, or for similar reasons. The system will try to send the command again.
+ Success: The command or plugin ran successfully. This is a terminal state.
+ Delivery Timed Out: The command wasn't delivered to the managed node before the delivery timeout expired. Delivery timeouts don't count against the parent command's `MaxErrors` limit, but they do contribute to whether the parent command status is Success or Incomplete. This is a terminal state.
+ Execution Timed Out: The command started to run on the managed node, but the execution wasn't complete before the timeout expired. Execution timeouts count against the `MaxErrors` limit of the parent command. This is a terminal state.
+ Failed: The command wasn't run successfully on the managed node. For a plugin, this indicates that the result code wasn't zero. For a command invocation, this indicates that the result code for one or more plugins wasn't zero. Invocation failures count against the `MaxErrors` limit of the parent command. This is a terminal state.
+ Cancelled: The command was terminated before it was completed. This is a terminal state.
+ Undeliverable: The command can't be delivered to the managed node. The node might not exist or might not be responding. Undeliverable invocations don't count against the parent command's `MaxErrors` limit and don't contribute to whether the parent command status is Success or Incomplete. This is a terminal state.
+ Terminated: The parent command exceeded its `MaxErrors` limit and subsequent command invocations were canceled by the system. This is a terminal state.
Type: String  
Length Constraints: Minimum length of 0. Maximum length of 100.
