Is there an event for game session termination?

When calling InitSDK in your server, it takes in a parameter of type ProcessParameters, which takes in a handler function called onProcessTerminate that I believe fits your needs in this situation. For more info, check https://docs.aws.amazon.com/gamelift/latest/developerguide/integration-server-sdk-cpp-ref-datatypes.html#integration-server-sdk-cpp-ref-dataypes-process

Thank you for your answer, but it doesn't fit my need. In case of process crashing, it cannot catch it. The gamelift service itself knows when a game is terminated, because it can gather logs, and upload them on s3, I believe, so I was wondering if there is an event there I could catch.

Would also like to know if there's an event similar to the FlexMatch or placement events that can trigger when a game session is terminated. Currently we're invoking a lambda on termination from the game script, but crashes are indeed a problem. We're currently tracking our player's status (playing/idle), and if a player is attempting an API call (for example, start matchmaking) when they're already in playing state, we're polling gamelift via describe player session to see if it shows as terminated and if it is, then we're assuming that the gamescript has crashed

Thanks for the reply!

Using the other API polling calls is discouraged, is that similar for this one? Is there a limit on the frequency of calling DescribeFleetEvent?

@REDACTEDUSER

process.on('uncaughtException', function(error) { InvokeSessionCompletionListenerLambda(); });

process.on('unhandledRejection', function(reason, p){ InvokeSessionCompletionListenerLambda(); });

That would be the case if there is a better alternative using push. Also, different from DescribeMatchmaking, DescribeGameSessionPlacement or DescribeGameSession, (which are the 3 APIs that customers incorrectly poll the most) which are not scalable to poll because you'd hit a bottleneck beyond a certain point as your game grows. However, since there is only limited number of fleet regardless of how large your game is, polling DescribeFleetEvent is reasonably scalable.
