Counting Closed Workflow Executions
-----------------------------------

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

The ``--domain`` and *either* ``--close-time-filter`` or ``--start-time-filter`` arguments are required. All other
arguments are optional.

Here is a basic example::

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

Result::

    {
        "count": 2,
        "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 ``--close-time-filter`` or ``--start-time-filter`` values to narrow the time range that is searched. Each
    of these is mutually exclusive: You can specify *only one of these* in a request.

-  use the ``--close-status-filter``, ``--execution-filter``, ``--tag-filter`` or ``--type-filter`` arguments to further
    filter the results. However, these arguments are also mutually exclusive.
