describe-fleet-capacity

Description

Retrieves the resource capacity settings for one or more fleets. For a container fleet, this operation also returns counts for game server container groups.

With multi-location fleets, this operation retrieves data for the fleet's home Region only. To retrieve capacity for remote locations, see DescribeFleetLocationCapacity .

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. Capacity values 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.

See also: AWS API Documentation

describe-fleet-capacity is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: FleetCapacity

Options

--fleet-ids (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)

Syntax:

"string" "string" ...

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To view capacity status for a list of fleets

The following describe-fleet-capacity example retrieves current capacity for two specified fleets.

Output

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. Changes in desired instance value can take up to 1 minute to be reflected.

(structure)

Current resource capacity settings for managed EC2 fleets and managed container fleets. For multi-location fleets, location values 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 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 -> (structure)

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 .

GameServerContainerGroupCounts -> (structure)

The number and status of game server container groups deployed in a container fleet.

PENDING -> (integer)

The number of container groups that are starting up but haven't 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.

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.
