describe_state_machine

SFN.Client.describe_state_machine(**kwargs)

Provides information about a state machine's definition, its IAM role Amazon Resource Name (ARN), and configuration. If the state machine ARN is a qualified state machine ARN, the response returned includes the Map state's label.

A qualified state machine ARN refers to a Distributed Map state defined within a state machine. For example, the qualified state machine ARN arn:partition:states:region:account-id:stateMachine:stateMachineName/mapStateLabel refers to a Distributed Map state with a label mapStateLabel in the state machine named stateMachineName .

Note

This operation is eventually consistent. The results are best effort and may not reflect very recent updates and changes.

Response Structure

• (dict) --
  • stateMachineArn (string) --

    The Amazon Resource Name (ARN) that identifies the state machine.

  • name (string) --

    The name of the state machine.

    A name must not contain:

    • white space
    • brackets < > { } [ ]
    • wildcard characters ? *
    • special characters " # % \ ^ | ~ ` $ & , ; : /
    • control characters ( U+0000-001F , U+007F-009F )

    To enable logging with CloudWatch Logs, the name should only contain 0-9, A-Z, a-z, - and _.

  • status (string) --

    The current status of the state machine.

  • definition (string) --

    The Amazon States Language definition of the state machine. See Amazon States Language.

  • roleArn (string) --

    The Amazon Resource Name (ARN) of the IAM role used when creating this state machine. (The IAM role maintains security by granting Step Functions access to Amazon Web Services resources.)

  • type (string) --

    The type of the state machine ( STANDARD or EXPRESS ).

  • creationDate (datetime) --

    The date the state machine is created.

  • loggingConfiguration (dict) --

    The LoggingConfiguration data type is used to set CloudWatch Logs options.

    • level (string) --

      Defines which category of execution history events are logged.

    • includeExecutionData (boolean) --

      Determines whether execution data is included in your log. When set to false , data is excluded.

    • destinations (list) --

      An array of objects that describes where your execution history events will be logged. Limited to size 1. Required, if your log level is not set to OFF .

      • (dict) --
        • cloudWatchLogsLogGroup (dict) --

          An object describing a CloudWatch log group. For more information, see AWS::Logs::LogGroup in the CloudFormation User Guide.

          • logGroupArn (string) --

            The ARN of the the CloudWatch log group to which you want your logs emitted to. The ARN must end with :*

  • tracingConfiguration (dict) --

    Selects whether X-Ray tracing is enabled.

    • enabled (boolean) --

      When set to true , X-Ray tracing is enabled.

  • label (string) --

    A user-defined or an auto-generated string that identifies a Map state. This parameter is present only if the stateMachineArn specified in input is a qualified state machine ARN.
