Use this data type to identify which files generated during a game session that you want the game server to upload to Amazon GameLift after the game session ends. The game server communicates LogParameters to Amazon GameLift in a ProcessReady() call.

Properties

 Description
LogPaths

The list of directory paths to game server log files you want Amazon GameLift to store for future access. The server process generates these files during each game session. You define file paths and names in your game server and store them in the root game build directory.

The log paths must be absolute. For example, if your game build stores game session logs in a path like MyGame\sessionLogs\, then the path would be c:\game\MyGame\sessionLogs on a Windows instance.
