GameLift / Client / describe_fleet_location_capacity



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 container fleet, this operation also returns counts for replica 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.

Response Structure

  • (dict) –

    • FleetCapacity (dict) –

      Resource capacity information for the requested fleet location. Capacity objects are returned only for fleets and locations that currently exist. Changes in desired instance value can take up to 1 minute to be reflected.

      • FleetId (string) –

        A unique identifier for the fleet associated with the location.

      • FleetArn (string) –

        The Amazon Resource Name ( ARN) that is assigned to a Amazon GameLift fleet resource and uniquely identifies it. ARNs are unique across all Regions. Format is arn:aws:gamelift:<region>::fleet/fleet-a1234567-b8c9-0d1e-2fa3-b45c6d7e8912.

      • InstanceType (string) –

        The Amazon EC2 instance type that is used for instances in a fleet. Instance type determines the computing resources in use, including CPU, memory, storage, and networking capacity. See Amazon Elastic Compute Cloud Instance Types for detailed descriptions.

      • InstanceCounts (dict) –

        The current number of instances in the fleet, listed by instance status. Counts for pending and terminating instances might be non-zero if the fleet is adjusting to a scaling event or if access to resources is temporarily affected.

        • DESIRED (integer) –

          Requested number of active instances. Amazon GameLift takes action as needed to maintain the desired number of instances. Capacity is scaled up or down by changing the desired instances. A change in the desired instances value can take up to 1 minute to be reflected when viewing a fleet’s capacity settings.

        • MINIMUM (integer) –

          The minimum instance count value allowed.

        • MAXIMUM (integer) –

          The maximum instance count value allowed.

        • PENDING (integer) –

          Number of instances that are starting but not yet active.

        • ACTIVE (integer) –

          Actual number of instances that are ready to host game sessions.

        • IDLE (integer) –

          Number of active instances that are not currently hosting a game session.

        • TERMINATING (integer) –

          Number of instances that are no longer active but haven’t yet been terminated.

      • Location (string) –

        The fleet location for the instance count information, expressed as an Amazon Web Services Region code, such as us-west-2.

      • ReplicaContainerGroupCounts (dict) –

        This property is used with the Amazon GameLift containers feature, which is currently in public preview. The number and status of replica container groups in a container fleet.

        • PENDING (integer) –

          The number of container groups that are starting up but have not yet registered.

        • ACTIVE (integer) –

          The number of container groups that have active game sessions.

        • IDLE (integer) –

          The number of container groups that have no active game sessions.

        • TERMINATING (integer) –

          The number of container groups that are in the process of shutting down.
