How can I view the console output for a game running on a remote linux server?

I built my game as a .x86_64 file and deployed it on a remote server via docker. The server is running Ubuntu 18.04 and I'm using Git Bash to SSH in. How can I view the console/debug output for the game?

 

If you mean the console output such as in the editor, that is output to the log file like any standalone build.

You can use the -logFile command line argument when you launch your game to direct the log file to a custom location.

If you mean actual console output, like you're printing to the terminal (which I haven't bothered trying from Unity in Linux), you can probably just use usual Unix/Linux output redirects to a file. Then you can tail that file to get updated on the current output. Maybe something like below.

Code (csharp):

1. ./blahgame.x86_64 -logFile ./myLogFile.log > ./currentoutput.txt

Code (csharp):

1. tail -F ./currentoutput.txt

 

Typically docker applications are authored to print all console output to standard out. However, if you don't start the application with a pseudo-tty (i.e., the "-t" option), you will sometimes not see console output. This is especially true if you use s6-overlay.

Also, you typically do not bash into a running container to view logs. Use an orchestrator, like kubernetes (complicated) or docker swarm + portainer (easy), which will give you an easy-to-use website to view logs from your containers (i.e., processes).



If this seems like a lot of IT for you, another choice is to configure an ILogger (a Unity interface for logging) that sends logs to a cloud log provider, like AWS CloudFront. There, you can view and search the logs in their interface.
