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.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

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.

Output

GameSessionQueues -> (list)

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

(structure)

Configuration for a game session placement mechanism that processes requests for new game sessions. A queue can be used on its own or as part of a matchmaking solution.

Name -> (string)

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

GameSessionQueueArn -> (string)

The Amazon Resource Name (ARN ) that is assigned to a GameLift game session queue resource and uniquely identifies it. ARNs are unique across all Regions. Format is arn:aws:gamelift:<region>::gamesessionqueue/<queue name> . 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 set of policies that act as a sliding cap on player latency. FleetIQ works to deliver low latency for most players in a game session. These policies ensure that no individual player can be placed into a game with unreasonably high latency. Use multiple policies to gradually relax latency requirements a step at a time. Multiple policies are applied based on their maximum allowed latency, starting with the lowest value.

(structure)

Sets a latency cap for individual players when placing a game session. With a latency policy in force, a game session cannot be placed in a fleet location where a player reports latency higher than the cap. Latency policies are used only with placement request that provide player latency information. Player latency policies can be stacked to gradually relax latency requirements over time.

Latency policies are part of a GameSessionQueue .

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 and/or fleet aliases that can be used to fulfill game session placement requests in the queue. Destinations are identified by either a fleet ARN or a fleet alias ARN, and are listed in order of placement preference.

(structure)

A fleet or alias designated in a game session queue. Queues fulfill requests for new game sessions by placing a new game session on any of the queue’s destinations.

Destinations are part of a GameSessionQueue .

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.

FilterConfiguration -> (structure)

A list of locations where a queue is allowed to place new game sessions. Locations are specified in the form of Amazon Web Services Region codes, such as us-west-2 . If this parameter is not set, game sessions can be placed in any queue location.

AllowedLocations -> (list)

A list of locations to allow game session placement in, in the form of Amazon Web Services Region codes such as us-west-2 .

(string)

PriorityConfiguration -> (structure)

Custom settings to use when prioritizing destinations and locations for game session placements. This configuration replaces the FleetIQ default prioritization process. Priority types that are not explicitly named will be automatically applied at the end of the prioritization process.

PriorityOrder -> (list)

The recommended sequence to use when prioritizing where to place new game sessions. Each type can only be listed once.

  • LATENCY – FleetIQ prioritizes locations where the average player latency (provided in each game session request) is lowest.

  • COST – FleetIQ prioritizes destinations with the lowest current hosting costs. Cost is evaluated based on the location, instance type, and fleet type (Spot or On-Demand) for each destination in the queue.

  • DESTINATION – FleetIQ prioritizes based on the order that destinations are listed in the queue configuration.

  • LOCATION – FleetIQ prioritizes based on the provided order of locations, as defined in LocationOrder .

(string)

LocationOrder -> (list)

The prioritization order to use for fleet locations, when the PriorityOrder property includes LOCATION . Locations are identified by Amazon Web Services Region codes such as us-west-2 . Each location can only be listed once.

(string)

CustomEventData -> (string)

Information that is added to all events that are related to this game session queue.

NotificationTarget -> (string)

An SNS topic ARN that is set up to receive game session placement notifications. See Setting up notifications for game session placement .

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.
