GetCommandInvocation

Returns detailed information about command execution for an invocation or plugin.

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.

   "CommandId": "string",
   "InstanceId": "string",
   "PluginName": "string"
}

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.

CommandId

(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 AWS Systems Manager.

Type: String

Pattern: (^i-(\w{8}|\w{17})$)|(^mi-\w{17}$)

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 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

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

CloudWatchOutputConfig

Amazon CloudWatch Logs information where Systems Manager sent the command output.

Type: CloudWatchOutputConfig object

CommandId

The parent command ID of the invocation plugin.

Type: String

Length Constraints: Fixed length of 36.

Comment

The comment text for the command.

Type: String

Length Constraints: Maximum length of 100.

DocumentName

The name of the document that was run. For example, AWS-RunShellScript.

DocumentVersion

The Systems Manager document (SSM document) version used in the request.

Pattern: ([$]LATEST|[$]DEFAULT|^[1-9][0-9]*$)

ExecutionElapsedTime

Duration since ExecutionStartDateTime.

Type: String

Pattern: ^([\-]?\d{4}(?!\d{2}\b))((-?)((0[1-9]|1[0-2])(\3([12]\d|0[1-9]|3[01]))?|W([0-4]\d|5[0-2])(-?[1-7])?|(00[1-9]|0[1-9]\d|[12]\d{2}|3([0-5]\d|6[1-6])))([T\s]((([01]\d|2[0-3])((:?)[0-5]\d)?|24\:?00)([\.,]\d(?!:))?)?(\17[0-5]\d([\.,]\d)?)?([zZ]|([\-])([01]\d|2[0-3]):?([0-5]\d)?)?)?)?$

ExecutionEndDateTime

The date and time the plugin finished running. Date and time are written in ISO 8601 format. For example, June 7, 2017 is represented as 2017-06-7. The following sample AWS CLI command uses the InvokedAfter filter.

aws ssm list-commands --filters key=InvokedAfter,value=2017-06-07T00:00:00Z

If the plugin hasn't started to run, the string is empty.

Type: String

ExecutionStartDateTime

The date and time the plugin started running. Date and time are written in ISO 8601 format. For example, June 7, 2017 is represented as 2017-06-7. The following sample AWS CLI command uses the InvokedBefore filter.

aws ssm list-commands --filters key=InvokedBefore,value=2017-06-07T00:00:00Z

If the plugin hasn't started to run, the string is empty.

Type: String

InstanceId

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, or on-premises server or VM in your hybrid environment that is configured for AWS Systems Manager.

Type: String

Pattern: (^i-(\w{8}|\w{17})$)|(^mi-\w{17}$)

PluginName

The name of the plugin, or step name, for which details are reported. For example, aws:RunShellScript is a plugin.

Type: String

Length Constraints: Minimum length of 4.

ResponseCode

The error level response code for the plugin script. If the response code is -1, then the command hasn't started running on the managed node, or it wasn't received by the node.

Type: Integer

StandardErrorContent

The first 8,000 characters written by the plugin to stderr. If the command hasn't finished running, then this string is empty.

Type: String

Length Constraints: Maximum length of 8000.

StandardErrorUrl

The URL for the complete text written by the plugin to stderr. If the command hasn't finished running, then this string is empty.

Type: String

StandardOutputContent

The first 24,000 characters written by the plugin to stdout. If the command hasn't finished running, if ExecutionStatus is neither Succeeded nor Failed, then this string is empty.

Type: String

Length Constraints: Maximum length of 24000.

StandardOutputUrl

The URL for the complete text written by the plugin to stdout in Amazon Simple Storage Service (Amazon S3). If an S3 bucket wasn't specified, then this string is empty.

Type: String

Status

The status of this invocation plugin. This status can be different than StatusDetails.

Type: String

StatusDetails

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 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.
