[ aws . gamelift ]



Retrieves utilization statistics for one or more fleets. Utilization data provides a snapshot of how the fleet’s hosting resources are currently being used. For fleets with remote locations, this operation retrieves data for the fleet’s home Region only. See DescribeFleetLocationUtilization to get utilization statistics for a fleet’s remote locations.

This operation can be used in the following ways:

  • To get utilization data for one or more specific fleets, provide a list of fleet IDs or fleet ARNs.
  • To get utilization 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 FleetUtilization object is returned for each requested fleet ID, unless the fleet identifier is not found. Each fleet utilization object includes a Location property, which is set to the fleet’s home Region.


Some API operations may limit the number of fleet IDs 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-utilization 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: FleetUtilization


[--fleet-ids <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]
[--endpoint-url <value>]
[--output <value>]
[--query <value>]
[--profile <value>]
[--region <value>]
[--version <value>]
[--color <value>]
[--ca-bundle <value>]
[--cli-read-timeout <value>]
[--cli-connect-timeout <value>]
[--cli-binary-format <value>]


--fleet-ids (list)

A unique identifier for the fleet to retrieve utilization data for. You can use either the fleet ID or ARN value. To retrieve attributes for all current fleets, do not include this parameter.



"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. 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.

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.

--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.



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 .

Example1: To view usage data for a list of fleets

The following describe-fleet-utilization example retrieves current usage information for one specified fleet.

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


    "FleetUtilization": [
        "FleetId": "fleet-a1b2c3d4-5678-90ab-cdef-EXAMPLE11111",
        "ActiveServerProcessCount": 100,
        "ActiveGameSessionCount": 62,
        "CurrentPlayerSessionCount": 329,
        "MaximumPlayerSessionCount": 1000

Example2: To request usage data for all fleets

The following describe-fleet-utilization returns fleet usage data for all fleets with any status. This example uses pagination parameters to return data for two fleets at a time.

aws gamelift describe-fleet-utilization \
    --limit 2


    "FleetUtilization": [
            "FleetId": "fleet-1111aaaa-22bb-33cc-44dd-5555eeee66ff",
            "ActiveServerProcessCount": 100,
            "ActiveGameSessionCount": 13,
            "CurrentPlayerSessionCount": 98,
            "MaximumPlayerSessionCount": 1000
            "FleetId": "fleet-2222bbbb-33cc-44dd-55ee-6666ffff77aa",
            "ActiveServerProcessCount": 100,
            "ActiveGameSessionCount": 62,
            "CurrentPlayerSessionCount": 329,
            "MaximumPlayerSessionCount": 1000
    "NextToken": "eyJhd3NBY2NvdW50SWQiOnsicyI6IjMwMjc3NjAxNjM5OCJ9LCJidWlsZElkIjp7InMiOiJidWlsZC01NWYxZTZmMS1jY2FlLTQ3YTctOWI5ZS1iYjFkYTQwMjEXAMPLE2"

Call the command a second time, passing the NextToken value as the argument to the --next-token parameter to see the next two results.

aws gamelift describe-fleet-utilization \
    --limit 2 \
    --next-token eyJhd3NBY2NvdW50SWQiOnsicyI6IjMwMjc3NjAxNjM5OCJ9LCJidWlsZElkIjp7InMiOiJidWlsZC01NWYxZTZmMS1jY2FlLTQ3YTctOWI5ZS1iYjFkYTQwMjEXAMPLE2

Repeat until the response no longer includes a NextToken value in the output.
