// DescribeFleetCapacityRequest returns a request value for making API operation for
// Amazon GameLift.
//
// Retrieves the current capacity statistics for one or more fleets. These statistics
// present a snapshot of the fleet's instances and provide insight on current
// or imminent scaling activity. To get statistics on game hosting activity
// in the fleet, see DescribeFleetUtilization.
//
// You can request capacity for all fleets or specify a list of one or more
// fleet identifiers. When requesting multiple fleets, use the pagination parameters
// to retrieve results as a set of sequential pages. If successful, a FleetCapacity
// object is returned for each requested fleet ID. When a list of fleet IDs
// is provided, attribute objects are returned only for fleets that currently
// exist.
//
// Some API actions may limit the number of fleet IDs allowed in one request.
// If a request exceeds this limit, the request fails and the error message
// includes the maximum allowed.
