I'm not sure how easy this would be to add, but I think it'd be a great feature-
Monitor showing total players online at current time in all servers (for display on game server host website).
I have a small game written in C running in Linux with multiple servers (5 servers total, each allowing a maximum of 10 players) and all players "connect" through UDP sockets. The problem is, at the moment I run the 5 servers myself so if a lot of players join and the servers become full then I have to manually open more servers myself. I would like to automate this process somehow.
