GetCommandInvocation
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. To get the command execution status across managed nodes,
use ListCommands.

Request Parameters
For information about the parameters that are common to all actions, see Common Parameters.
The request accepts the following data in JSON format.

-
(Required) The parent command ID of the invocation plugin.
Type: String
Length Constraints: Fixed length of 36.
Required: Yes
- InstanceId
-
(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 Amazon Systems Manager.

Required: Yes
- PluginName
-
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 with theCommandId

aws:RunShellScript
is a plugin.Type: String
Length Constraints: Minimum length of 4.

-1
, then the command hasn't started running on the managed node, or it wasn't received by the node.Type: Integer

StatusDetails
.Type: String
Valid Values:
Pending | InProgress | Delayed | Success | Cancelled | TimedOut | Failed | Cancelling
- StatusDetails
-
A detailed status of the command execution for an invocation.
StatusDetails
includes more information thanStatus
because it includes states resulting from error and concurrency control parameters.StatusDetails
can show different results thanStatus
. For more information about these statuses, see Understanding command statuses in the Amazon 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.
