search_game_sessions(**kwargs)¶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:
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 or GameSessionArn value.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.Note
Returned values forplayerSessionCountandhasAvailablePlayerSessionschange 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.

Request Syntax
response = client.search_game_sessions(
FleetId='string',
AliasId='string',
Location='string',
FilterExpression='string',
SortExpression='string',
Limit=123,
NextToken='string'
)
us-west-2 .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:
gameSessionName , gameSessionId , gameSessionProperties , maximumSessions , creationTimeMillis , playerSessionCount , hasAvailablePlayerSessions .= , <> , < , > , <= , >= .= 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:
= , <> , < , > , <= , >=For example, this filter expression retrieves game sessions hosting at least ten players that have an open player slot: "maximumSessions>=10 AND hasAvailablePlayerSessions=true" .
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:
gameSessionName , gameSessionId , gameSessionProperties , maximumSessions , creationTimeMillis , playerSessionCount , hasAvailablePlayerSessions .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.
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.dict

Response Structure
(dict) --
GameSessions (list) --
A collection of objects containing game session properties for each session that matches the request.
(dict) --
Properties describing a game session.
A game session in ACTIVE status can host players. When a game session ends, its status is set to TERMINATED .
Once the session ends, the game session object is retained for 30 days. This means you can reuse idempotency token values after this time. Game session logs are retained for 14 days.
GameSessionId (string) --
A unique identifier for the game session. A game session ARN has the following format: arn:aws:gamelift:<region>::gamesession/<fleet ID>/<custom ID string or idempotency token> .
Name (string) --
A descriptive label that is associated with a game session. Session names do not need to be unique.
FleetId (string) --
A unique identifier for the fleet that the game session is running on.
FleetArn (string) --
The Amazon Resource Name ( ARN ) associated with the GameLift fleet that this game session is running on.
CreationTime (datetime) --
A time stamp indicating when this data object was created. Format is a number expressed in Unix time as milliseconds (for example "1469498468.057" ).
TerminationTime (datetime) --
A time stamp indicating when this data object was terminated. Format is a number expressed in Unix time as milliseconds (for example "1469498468.057" ).
CurrentPlayerSessionCount (integer) --
Number of players currently in the game session.
MaximumPlayerSessionCount (integer) --
The maximum number of players that can be connected simultaneously to the game session.
Status (string) --
Current status of the game session. A game session must have an ACTIVE status to have player sessions.
StatusReason (string) --
Provides additional information about game session status. INTERRUPTED indicates that the game session was hosted on a spot instance that was reclaimed, causing the active game session to be terminated.
GameProperties (list) --
A set of custom properties for a game session, formatted as key:value pairs. These properties are passed to a game server process with a request to start a new game session (see Start a Game Session ).
(dict) --
Set of key-value pairs that contain information about a game session. When included in a game session request, these properties communicate details to be used when setting up the new game session. For example, a game property might specify a game mode, level, or map. Game properties are passed to the game server process when initiating a new game session. For more information, see the GameLift Developer Guide.
Key (string) --
The game property identifier.
Value (string) --
The game property value.
IpAddress (string) --
The IP address of the game session. To connect to a GameLift game server, an app needs both the IP address and port number.
DnsName (string) --
The DNS identifier assigned to the instance that is running the game session. Values have the following format:
<unique identifier>.<region identifier>.amazongamelift.com .ec2-<unique identifier>.compute.amazonaws.com . (See Amazon EC2 Instance IP Addressing.)When connecting to a game session that is running on a TLS-enabled fleet, you must use the DNS name, not the IP address.
Port (integer) --
The port number for the game session. To connect to a GameLift game server, an app needs both the IP address and port number.
PlayerSessionCreationPolicy (string) --
Indicates whether or not the game session is accepting new players.
CreatorId (string) --
A unique identifier for a player. This ID is used to enforce a resource protection policy (if one exists), that limits the number of game sessions a player can create.
GameSessionData (string) --
A set of custom game session properties, formatted as a single string value. This data is passed to a game server process with a request to start a new game session (see Start a Game Session ).
MatchmakerData (string) --
Information about the matchmaking process that was used to create the game session. It is in JSON syntax, formatted as a string. In addition the matchmaking configuration used, it contains data on all players assigned to the match, including player attributes and team assignments. For more details on matchmaker data, see Match Data. Matchmaker data is useful when requesting match backfills, and is updated whenever new players are added during a successful backfill (see StartMatchBackfill ).
Location (string) --
The fleet location where the game session is running. This value might specify the fleet's home Region or a remote location. Location is 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.
