get-command-invocation¶

Description¶

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 instance, use ListCommandInvocations . To get the command execution status across instances, use ListCommands .

Synopsis¶

  get-command-invocation
--command-id <value>
--instance-id <value>
[--plugin-name <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--command-id (string)

(Required) The parent command ID of the invocation plugin.

--instance-id (string)

(Required) The ID of the managed instance targeted by the command. A managed instance can be an Amazon Elastic Compute Cloud (Amazon EC2) instance or an instance in your hybrid environment that is configured for Amazon Web Services Systems Manager.

--plugin-name (string)

The name of the plugin for which you want detailed results. If the document contains only one plugin, you can omit the name and details for that plugin. If the document contains more than one plugin, you must specify the name of the plugin for which you want to view details.

Plugin names are also referred to as step names in Systems Manager documents (SSM documents). For example, aws:RunShellScript is a plugin.

To find the PluginName , check the document content and find the name of the plugin. Alternatively, use ListCommandInvocations with the CommandId and Details parameters. The PluginName is the Name attribute of the CommandPlugin object in the CommandPlugins list.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples¶

To display the details of a command invocation

The following get-command-invocation example lists all the invocations of the specified command on the specified instance.

aws ssm get-command-invocation \
    --command-id "ef7fdfd8-9b57-4151-a15c-db9a12345678" \
    --instance-id "i-1234567890abcdef0"

Output:

}

Output¶

CommandId -> (string)

The parent command ID of the invocation plugin.

InstanceId -> (string)

The ID of the managed instance targeted by the command. A managed instance can be an EC2 instance or an instance in your hybrid environment that is configured for Systems Manager.

Comment -> (string)

The comment text for the command.

DocumentName -> (string)

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

DocumentVersion -> (string)

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

PluginName -> (string)

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

ResponseCode -> (integer)

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

ExecutionStartDateTime -> (string)

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 Amazon Web Services 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.

ExecutionElapsedTime -> (string)

Duration since ExecutionStartDateTime .

ExecutionEndDateTime -> (string)

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 Amazon Web Services 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.

Status -> (string)

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

StatusDetails -> (string)

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 Amazon Web Services Systems Manager User Guide . StatusDetails can be one of the following values:

Pending: The command hasn’t been sent to the instance.

In Progress: The command has been sent to the instance 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 instance might not be available because of network issues, because the instance 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 instance 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 instance, 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 instance. 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.

Canceled: The command was terminated before it was completed. This is a terminal state.

Undeliverable: The command can’t be delivered to the instance. The instance 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.

StandardOutputContent -> (string)

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.

StandardOutputUrl -> (string)

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.

StandardErrorContent -> (string)

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

StandardErrorUrl -> (string)

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

CloudWatchOutputConfig -> (structure)

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

CloudWatchLogGroupName -> (string)

The name of the CloudWatch Logs log group where you want to send command output. If you don’t specify a group name, Amazon Web Services Systems Manager automatically creates a log group for you. The log group uses the following naming format:

``aws/ssm/SystemsManagerDocumentName ``

CloudWatchOutputEnabled -> (boolean)

Enables Systems Manager to send command output to CloudWatch Logs.
