count-open-workflow-executions

Description

Returns the number of open 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 .

Options

--domain (string)

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

--start-time-filter (structure)

Specifies the start time criteria that workflow executions must meet in order to be counted.

oldestDate -> (timestamp)

Specifies the oldest start or close date and time to return.

latestDate -> (timestamp)

Specifies the latest start or close date and time to return.

Shorthand Syntax:

oldestDate=timestamp,latestDate=timestamp

JSON Syntax:

{
  "oldestDate": timestamp,
  "latestDate": timestamp
}

--type-filter (structure)

Specifies the type of the workflow executions to be counted.

Note

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

name -> (string)

Name of the workflow type.

version -> (string)

Version of the workflow type.

Shorthand Syntax:

name=string,version=string

JSON Syntax:

{
  "name": "string",
  "version": "string"
}

--tag-filter (structure)

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

Note

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

tag -> (string)

Specifies the tag that must be associated with the execution for it to meet the filter criteria.

Tags may only contain unicode letters, digits, whitespace, or these symbols: _ . : / = + - @ .

Shorthand Syntax:

tag=string

JSON Syntax:

{
  "tag": "string"
}

--execution-filter (structure)

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

Note

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

workflowId -> (string)

The workflowId to pass of match the criteria of this filter.

Shorthand Syntax:

workflowId=string

JSON Syntax:

{
  "workflowId": "string"
}

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

Counting Open Workflow Executions

You can use swf count-open-workflow-executions to retrieve the number of open workflow executions for a given domain. You can specify filters to count specific classes of executions.

The --domain and --start-time-filter arguments are required. All other arguments are optional.

aws swf count-open-workflow-executions \
    --domain DataFrobtzz \
    --start-time-filter "{ \"latestDate\" : 1377129600, \"oldestDate\" : 1370044800 }"

Output:

{
    "count": 4,
    "truncated": false
}

If "truncated" is true, then "count" represents the maximum number that can be returned by Amazon SWF. Any further results are truncated.

To reduce the number of results returned, you can:

  • modify the --start-time-filter values to narrow the time range that is searched.
  • use the --close-status-filter, --execution-filter, --tag-filter or --type-filter arguments to further
    filter the results. Each of these is mutually exclusive: You can specify only one of these in a request.

For more information, see CountOpenWorkflowExecutions in the Amazon Simple Workflow Service API Reference

Output

count -> (integer)

The number of workflow executions.

truncated -> (boolean)

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.
