describe_fleet_capacity#

GameLift.Client.describe_fleet_capacity(**kwargs)#

Retrieves the resource capacity settings for one or more fleets. The data returned includes the current fleet capacity (number of EC2 instances), and settings that can control how capacity scaling. For fleets with remote locations, this operation retrieves data for the fleet’s home Region only.

This operation can be used in the following ways:

  • To get capacity data for one or more specific fleets, provide a list of fleet IDs or fleet ARNs.

  • To get capacity data for all fleets, do not provide a fleet identifier.

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. Each FleetCapacity object includes a Location property, which is set to the fleet’s home Region. When a list of fleet IDs is provided, attribute objects are returned only for fleets that currently exist.

Note

Some API operations may limit the number of fleet IDs that are allowed in one request. If a request exceeds this limit, the request fails and the error message includes the maximum allowed.

Request Syntax

response = client.describe_fleet_capacity(
    FleetIds=[
        'string',
    ],
    Limit=123,
    NextToken='string'
)
Parameters:

  • FleetIds (list) –

    A unique identifier for the fleet to retrieve capacity information for. You can use either the fleet ID or ARN value. Leave this parameter empty to retrieve capacity information for all fleets.

    • (string) –

  • Limit (integer) – 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.

  • NextToken (string) – A 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.

Response Structure

  • (dict) –

    • FleetCapacity (list) –

      A collection of objects that contains capacity information for each requested fleet ID. Capacity objects are returned only for fleets that currently exist.

      • (dict) –

        Current resource capacity settings in a specified fleet or location. The location value might refer to a fleet’s remote location or its home Region.

        • 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 all instances in a fleet. The 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) –

          Resource capacity settings. Fleet capacity is measured in Amazon EC2 instances. Pending and terminating counts are non-zero when the fleet capacity is adjusting to a scaling event or if access to resources is temporarily affected.

          • DESIRED (integer) –

            Ideal number of active instances. GameLift will always try to maintain the desired number of instances. Capacity is scaled up or down by changing the desired instances.

          • 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.

    • NextToken (string) –

      A token that indicates where to resume retrieving results on the next call to this operation. If no token is returned, these results represent the end of the list.
