describe-game-session-queues

Description

Retrieves the properties for one or more game session queues. When requesting multiple queues, use the pagination parameters to retrieve results as a set of sequential pages. If successful, a GameSessionQueue object is returned for each requested queue. When specifying a list of queues, objects are returned only for queues that currently exist in the Region.

describe-game-session-queues 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: GameSessionQueues

Synopsis

  describe-game-session-queues
[--names <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--names (list)

A list of queue names to retrieve information for. You can use either the queue ID or ARN value. To request settings for all queues, leave this parameter empty.

(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

To view game session queues

The following describe-game-session-queues example retrieves properties for two specified queues.

aws gamelift describe-game-session-queues \
    --names MegaFrogRace-NA MegaFrogRace-EU

Output:

Output

GameSessionQueues -> (list)

A collection of objects that describe the requested game session queues.

(structure)

Configuration of a queue that is used to process game session placement requests. The queue configuration identifies several game features:

  • The destinations where a new game session can potentially be hosted. Amazon GameLift tries these destinations in an order based on either the queue’s default order or player latency information, if provided in a placement request. With latency information, Amazon GameLift can place game sessions where the majority of players are reporting the lowest possible latency.

  • The length of time that placement requests can wait in the queue before timing out.

  • A set of optional latency policies that protect individual players from high latencies, preventing game sessions from being placed where any individual player is reporting latency higher than a policy’s maximum.

  • CreateGameSessionQueue

  • DescribeGameSessionQueues

  • UpdateGameSessionQueue

  • DeleteGameSessionQueue

Name -> (string)

A descriptive label that is associated with game session queue. Queue names must be unique within each Region.

GameSessionQueueArn -> (string)

Amazon Resource Name (ARN ) that is assigned to a GameLift game session queue resource and uniquely identifies it. ARNs are unique across all Regions. In a GameLift game session queue ARN, the resource ID matches the Name value.

TimeoutInSeconds -> (integer)

The maximum time, in seconds, that a new game session placement request remains in the queue. When a request exceeds this time, the game session placement changes to a TIMED_OUT status.

PlayerLatencyPolicies -> (list)

A collection of latency policies to apply when processing game sessions placement requests with player latency information. Multiple policies are evaluated in order of the maximum latency value, starting with the lowest latency values. With just one policy, the policy is enforced at the start of the game session placement for the duration period. With multiple policies, each policy is enforced consecutively for its duration period. For example, a queue might enforce a 60-second policy followed by a 120-second policy, and then no policy for the remainder of the placement.

(structure)

Queue setting that determines the highest latency allowed for individual players when placing a game session. When a latency policy is in force, a game session cannot be placed with any fleet in a Region where a player reports latency higher than the cap. Latency policies are only enforced when the placement request contains player latency information.

  • UpdateGameSessionQueue

  • DeleteGameSessionQueue

MaximumIndividualPlayerLatencyMilliseconds -> (integer)

The maximum latency value that is allowed for any player, in milliseconds. All policies must have a value set for this property.

PolicyDurationSeconds -> (integer)

The length of time, in seconds, that the policy is enforced while placing a new game session. A null value for this property means that the policy is enforced until the queue times out.

Destinations -> (list)

A list of fleets that can be used to fulfill game session placement requests in the queue. Fleets are identified by either a fleet ARN or a fleet alias ARN. Destinations are listed in default preference order.

(structure)

Fleet designated in a game session queue. Requests for new game sessions in the queue are fulfilled by starting a new game session on any destination that is configured for a queue.

  • DescribeGameSessionQueues

  • UpdateGameSessionQueue

  • DeleteGameSessionQueue

DestinationArn -> (string)

The Amazon Resource Name (ARN) that is assigned to fleet or fleet alias. ARNs, which include a fleet ID or alias ID and a Region name, provide a unique identifier across all Regions.

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.
