-- Returns a list of monitors created with the CreateMonitor operation and
-- CreateAutoPredictor operation. For each monitor resource, this operation
-- returns of a summary of its properties, including its Amazon Resource
-- Name (ARN). You can retrieve a complete set of properties of a monitor
-- resource by specify the monitor\'s ARN in the DescribeMonitor operation.
--
-- This operation returns paginated results.
