CountClosedWorkflowExecutions

Returns the number of closed workflow executions within the given domain that meet the specified filtering criteria.

Note

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.
Constrain the following parameters by using a Condition element with the appropriate keys.
- tagFilter.tag: String constraint. The key is swf:tagFilter.tag.
- typeFilter.name: String constraint. The key is swf:typeFilter.name.
- typeFilter.version: String constraint. The key is swf:typeFilter.version.

If the caller doesn't 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 is set to OPERATION_NOT_PERMITTED. For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows in the Amazon SWF Developer Guide.

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.

closeStatusFilter

If specified, only workflow executions that match this close status are counted. This filter has an affect only if executionStatus is specified as CLOSED.

Note

closeStatusFilter, executionFilter, typeFilter and tagFilter are mutually exclusive. You can specify at most one of these in a request.

Type: CloseStatusFilter object

Required: No

closeTimeFilter

If specified, only workflow executions that meet the close time criteria of the filter are counted.

Note

startTimeFilter and closeTimeFilter are mutually exclusive. You must specify one of these in a request but not both.

Type: ExecutionTimeFilter object

Required: No

domain

The name of the domain containing the workflow executions to count.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 256.

Required: Yes

executionFilter

If specified, only workflow executions matching the WorkflowId in the filter are counted.

Note

closeStatusFilter, executionFilter, typeFilter and tagFilter are mutually exclusive. You can specify at most one of these in a request.

Type: WorkflowExecutionFilter object

Required: No

startTimeFilter

If specified, only workflow executions that meet the start time criteria of the filter are counted.

Note

startTimeFilter and closeTimeFilter are mutually exclusive. You must specify one of these in a request but not both.

Type: ExecutionTimeFilter object

Required: No

tagFilter

If specified, only executions that have a tag that matches the filter are counted.

Note

closeStatusFilter, executionFilter, typeFilter and tagFilter are mutually exclusive. You can specify at most one of these in a request.

Type: TagFilter object

Required: No

typeFilter

If specified, indicates the type of the workflow executions to be counted.

Note

closeStatusFilter, executionFilter, typeFilter and tagFilter are mutually exclusive. You can specify at most one of these in a request.

Type: WorkflowTypeFilter object

Required: No

Response Syntax

}

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.

count

The number of workflow executions.

Type: Integer

Valid Range: Minimum value of 0.

truncated

If set to true, indicates that the actual count was more than the maximum supported by this API and the count returned is the truncated value.

Type: Boolean

Errors

For information about the errors that are common to all actions, see Common Errors.

OperationNotPermittedFault

Returned when the caller doesn't have sufficient permissions to invoke the action.

HTTP Status Code: 400

UnknownResourceFault

Returned when the named resource cannot be found with in the scope of this operation (region or domain). This could happen if the named resource was never created or is no longer available for this operation.

HTTP Status Code: 400
