Returns information about the specified workflow execution including its type and some statistics.

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

Access Control

You can use IAM policies to control this action's access to Amazon SWF resources as follows:

  • Use a Resource element with the domain name to limit the action to only specified domains.
  • Use an Action element to allow or deny permission to call this action.
  • You cannot use an IAM policy to constrain this action's parameters.

If the caller does not have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails. The associated event attribute's cause parameter will be set to OPERATION_NOT_PERMITTED. For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows.

See: AWS API Reference for DescribeWorkflowExecution.


Creating a Request

describeWorkflowExecution Source

Creates a value of DescribeWorkflowExecution with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

Request Lenses

dweDomain :: Lens' DescribeWorkflowExecution Text Source

The name of the domain containing the workflow execution.

Destructuring the Response

Response Lenses

dwersLatestActivityTaskTimestamp :: Lens' DescribeWorkflowExecutionResponse (Maybe UTCTime) Source

The time when the last activity task was scheduled for this workflow execution. You can use this information to determine if the workflow has not made progress for an unusually long period of time and might require a corrective action.

dwersLatestExecutionContext :: Lens' DescribeWorkflowExecutionResponse (Maybe Text) Source

The latest executionContext provided by the decider for this workflow execution. A decider can provide an executionContext (a free-form string) when closing a decision task using RespondDecisionTaskCompleted.

dwersExecutionConfiguration :: Lens' DescribeWorkflowExecutionResponse WorkflowExecutionConfiguration Source

The configuration settings for this workflow execution including timeout values, tasklist etc.

dwersOpenCounts :: Lens' DescribeWorkflowExecutionResponse WorkflowExecutionOpenCounts Source

The number of tasks for this workflow execution. This includes open and closed tasks of all types.
