// Retrieves utilization statistics for one or more fleets. These statistics
// provide insight into how available hosting resources are currently being
// used. To get statistics on available hosting resources, see DescribeFleetCapacity.
//
// You can request utilization data for all fleets, or specify a list of one
// or more fleet IDs. When requesting multiple fleets, use the pagination parameters
// to retrieve results as a set of sequential pages. If successful, a FleetUtilization
// object is returned for each requested fleet ID, unless the fleet identifier
// is not found.
//
// 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.
