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.

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

[--cli-input-json | --cli-input-yaml]

--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
| --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 theNextToken
value in thestarting-token
argument of a subsequent command. Do not use theNextToken
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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.
--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.
--output
(string)
The formatting style for command output.
json
text
table
yaml
yaml-stream
--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.
--cli-binary-format
(string)
The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb://
will always be treated as binary and use the file contents directly regardless of the cli-binary-format
setting. When using file://
the file contents will need to properly formatted for the configured cli-binary-format
.
base64
raw-in-base64-out
--no-cli-pager
(boolean)
Disable cli pager for output.
--cli-auto-prompt
(boolean)
Automatically prompt for CLI input parameters.
--no-cli-auto-prompt
(boolean)
Disable automatically prompt for CLI input parameters.
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 .

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

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.
