Description

Retrieves all active game sessions that match a set of search criteria and sorts them into a specified order. This operation is not designed to be continually called to track game session status. This practice can cause you to exceed your API limit, which results in errors. Instead, you must configure configure an Amazon Simple Notification Service (SNS) topic to receive notifications from FlexMatch or queues. Continuously polling game session status with DescribeGameSessions should only be used for games in development with low game session usage. When searching for game sessions, you specify exactly where you want to search and provide a search filter expression, a sort expression, or both. A search request can search only one fleet, but it can search all of a fleet's locations. This operation can be used in the following ways:
  • To search all game sessions that are currently running on all locations in a fleet, provide a fleet or alias ID. This approach returns game sessions in the fleet's home Region and all remote locations that fit the search criteria.
  • To search all game sessions that are currently running on a specific fleet location, provide a fleet or alias ID and a location name. For location, you can specify a fleet's home Region or any remote location.
Use the pagination parameters to retrieve results as a set of sequential pages. If successful, a GameSession object is returned for each game session that matches the request. Search finds game sessions that are in ACTIVE status only. To retrieve information on game sessions in other statuses, use DescribeGameSessions. You can search or sort by the following game session attributes:
  • gameSessionId -- A unique identifier for the game session. You can use either a GameSessionId or GameSessionArn value.
  • gameSessionName -- Name assigned to a game session. This value is set when requesting a new game session with CreateGameSession or updating with UpdateGameSession. Game session names do not need to be unique to a game session.
  • gameSessionProperties -- Custom data defined in a game session's GameProperty parameter. GameProperty values are stored as key:value pairs; the filter expression must indicate the key and a string to search the data values for. For example, to search for game sessions with custom data containing the key:value pair "gameMode:brawl", specify the following: gameSessionProperties.gameMode = "brawl". All custom data values are searched as strings.
  • maximumSessions -- Maximum number of player sessions allowed for a game session. This value is set when requesting a new game session with CreateGameSession or updating with UpdateGameSession.
  • creationTimeMillis -- Value indicating when a game session was created. It is expressed in Unix time as milliseconds.
  • playerSessionCount -- Number of players currently connected to a game session. This value changes rapidly as players join the session or drop out.
  • hasAvailablePlayerSessions -- Boolean value indicating whether a game session has reached its maximum number of players. It is highly recommended that all search requests include this filter attribute to optimize search performance and return only sessions that players can join.
Returned values for playerSessionCount and hasAvailablePlayerSessions change quickly as players join sessions and others drop out. Results should be considered a snapshot in time. Be sure to refresh search results often, and handle sessions that fill up before a player can join.

This cmdlet automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. To disable autopagination, use -NoAutoIteration.

Parameters

-AliasId <String>
A unique identifier for the alias associated with the fleet to search for active game sessions. You can use either the alias ID or ARN value. Each request must reference either a fleet ID or alias ID, but not both.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-FilterExpression <String>
String containing the search criteria for the session search. If no filter expression is included, the request returns results for all game sessions in the fleet that are in ACTIVE status.A filter expression can contain one or multiple conditions. Each condition consists of the following:
  • Operand -- Name of a game session attribute. Valid values are gameSessionName, gameSessionId, gameSessionProperties, maximumSessions, creationTimeMillis, playerSessionCount, hasAvailablePlayerSessions.
  • Comparator -- Valid comparators are: =, <>, <, >, <=, >=.
  • Value -- Value to be searched for. Values may be numbers, boolean values (true/false) or strings depending on the operand. String values are case sensitive and must be enclosed in single quotes. Special characters must be escaped. Boolean and string values can only be used with the comparators = and <>. For example, the following filter expression searches on gameSessionName: "FilterExpression": "gameSessionName = 'Matt\\'s Awesome Game 1'".
To chain multiple conditions in a single expression, use the logical keywords AND, OR, and NOT and parentheses as needed. For example: x AND y AND NOT z, NOT (x OR y).Session search evaluates conditions from left to right using the following precedence rules:
  1. =, <>, <, >, <=, >=
  2. Parentheses
  3. NOT
  4. AND
  5. OR
For example, this filter expression retrieves game sessions hosting at least ten players that have an open player slot: "maximumSessions>=10 AND hasAvailablePlayerSessions=true".
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-FleetId <String>
A unique identifier for the fleet to search for active game sessions. You can use either the fleet ID or ARN value. Each request must reference either a fleet ID or alias ID, but not both.
Required?False
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-Limit <Int32>
The maximum number of results to return. Use this parameter with NextToken to get results as a set of sequential pages. The maximum number of results returned is 20, even if this value is not set or is set higher than 20.
Note: In AWSPowerShell and AWSPowerShell.NetCore this parameter is used to limit the total number of items returned by the cmdlet.
In AWS.Tools this parameter is simply passed to the service to specify how many items should be returned by each service call.
Pipe the output of this cmdlet into Select-Object -First to terminate retrieving data pages early and control the number of items returned.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesMaxItems
-Location <String>
A fleet location to search for game sessions. You can specify a fleet's home Region or a remote location. Use the Amazon Web Services Region code format, such as us-west-2.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NextToken <String>
A token that indicates the start of the next sequential page of results. Use the token that is returned with a previous call to this operation. To start at the beginning of the result set, do not specify a value.
Note: This parameter is only used if you are manually controlling output pagination of the service API call.
In order to manually control output pagination, use '-NextToken $null' for the first call and '-NextToken $AWSHistory.LastServiceResponse.NextToken' for subsequent calls.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NoAutoIteration <SwitchParameter>
By default the cmdlet will auto-iterate and retrieve all results to the pipeline by performing multiple service calls. If set, the cmdlet will retrieve only the next 'page' of results using the value of NextToken as the start point.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the FleetId parameter. The -PassThru parameter is deprecated, use -Select '^FleetId' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'GameSessions'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.GameLift.Model.SearchGameSessionsResponse). Specifying the name of a property of type Amazon.GameLift.Model.SearchGameSessionsResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-SortExpression <String>
Instructions on how to sort the search results. If no sort expression is included, the request returns results in random order. A sort expression consists of the following elements:
  • Operand -- Name of a game session attribute. Valid values are gameSessionName, gameSessionId, gameSessionProperties, maximumSessions, creationTimeMillis, playerSessionCount, hasAvailablePlayerSessions.
  • Order -- Valid sort orders are ASC (ascending) and DESC (descending).
For example, this sort expression returns the oldest active sessions first: "SortExpression": "creationTimeMillis ASC". Results with a null value for the sort operand are returned at the end of the list.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
