question

Hi @Markus Henschel,

>>…But how do we get the directory we are supposed to log into?

You can use the getLogsDirectory() function to get the log directory:

std::string logFolder = Microsoft::Azure::Gaming::GSDK::getLogsDirectory();

This happens during runtime.

>>… Can the log folder in a could based environment with Thunderhead Servers really come from a json config file?...Will the above work reliably?

The log folder are indeed coming from the JSON file that the GSDK agent initialized, a sample config file would be like this: gsdkSampleConfigWindows.json, however, this configuration is already existed on the cloud based environment and there is no a predefined Environment variable for usage. Therefore, your way may not work since you don't know the exact log folder before the game server starts. Moreover, UE4 doesn’t support changing the log location at runtime and it looked like the log folder path was only available from the GSDK. Therefore, a possible workaround would be to create an output redirector to create a second log to log all future log messages to the right location when the server starts as the answer suggested:

FString ServerLogDirectory = <query the GSDK for GSDK::LOG_FOLDER_KEY>FString 

ServerLogPath = FPaths::Combine(ServerLogDirectory, TEXT("MyServerLog.log"));

FOutputDeviceRedirector::Get()->AddOutputDevice(new FOutputDeviceFile(*ServerLogPath));
