describe-fleet-capacity

Description

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. See DescribeFleetLocationCapacity to get capacity settings for a fleet’s remote locations.

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.

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

Synopsis

  describe-fleet-capacity
[--fleet-ids <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--fleet-ids (list)

A unique identifier for the fleet(s) 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 | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples

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

aws gamelift describe-fleet-capacity \
    --fleet-ids arn:aws:gamelift:us-west-2::fleet/fleet-a1b2c3d4-5678-90ab-cdef-EXAMPLE11111 fleet-a1b2c3d4-5678-90ab-cdef-EXAMPLE22222

Output:

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.

(structure)

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 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 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 EC2 Instance Types for detailed descriptions.

InstanceCounts -> (structure)

The current instance count and capacity settings for the fleet location.

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.

The maximum instance count value allowed.

PENDING -> (integer)

Number of instances that are starting but not yet active.

Location -> (string)

The fleet location for the instance count information, expressed as an AWS 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.
