DescribeGameSessions

Retrieves a set of one or more game sessions in a specific fleet location. You can optionally filter the results by current game session status.

This operation can be used in the following ways:

To retrieve all game sessions that are currently running on all locations in a fleet, provide a fleet or alias ID, with an optional status filter. This approach returns all game sessions in the fleet's home Region and all remote locations.
To retrieve all game sessions that are currently running on a specific fleet location, provide a fleet or alias ID and a location name, with optional status filter. The location can be the fleet's home Region or any remote location.
To retrieve a specific game session, provide the game session ID. This approach looks for the game session ID in all fleets that reside in the AWS Region defined in the request.

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.

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 an Amazon Simple Notification Service (SNS) topic to receive notifications from FlexMatch or queues. Continuously polling with DescribeGameSessions should only be used for games in development with low game session usage.

Available in Amazon GameLift Local.

Pattern: ^alias-\S+|^arn:.*:alias\/alias-\S+

Required: No

FleetId

A unique identifier for the fleet to retrieve game sessions for. You can use either the fleet ID or ARN value.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 512.

A unique identifier for the game session to retrieve.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 512.

Pattern: [a-zA-Z0-9:/-]+

Limit

The maximum number of results to return. Use this parameter with NextToken to get results as a set of sequential pages.
