DescribeFleetLocationCapacity

Retrieves the resource capacity settings for a fleet location. The data returned includes the current capacity (number of EC2 instances) and some scaling settings for the requested fleet location. For a managed container fleet, this operation also returns counts for game server container groups.

Use this operation to retrieve capacity information for a fleet's remote location or home Region (you can also retrieve home Region capacity by calling DescribeFleetCapacity).

To retrieve capacity data, identify a fleet and location.

If successful, a FleetCapacity object is returned for the requested fleet location.

Examples

Request capacity information for a fleet location

This example retrieves fleet capacity information for a remote fleet location. The returned FleetCapacity object describes the capacity at the specified location only. To get a fleet's current total capacity, first call DescribeFleetLocationAttributes to get a list of the fleet's remote locations, and then call DescribeFleetLocationCapacity for each remote location plus the home Region, and sum the results for active instances.

HTTP requests are authenticated using an AWS Signature Version 4 signature in the Authorization header field.
