describeFleetCapacity method

Future<DescribeFleetCapacityOutput> describeFleetCapacity({ List<String>? fleetIds, int? limit, String? nextToken, })

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. Learn more

Parameter fleetIds : A unique identifier for a fleet(s) to retrieve capacity information for. You can use either the fleet ID or ARN value.

Parameter limit : The maximum number of results to return. Use this parameter with NextToken to get results as a set of sequential pages. This parameter is ignored when the request specifies one or a list of fleet IDs.

Parameter nextToken : Token that indicates the start of the next sequential page of results. Use the token that is returned with a previous call to this operation. To start at the beginning of the result set, do not specify a value. This parameter is ignored when the request specifies one or a list of fleet IDs.
