A remote installation is what will suits your situation.
Install B3 on your own machine and set it up to remotely read your game log file on your gameserver host server.
This way, the only load you put on your gameserver host is the FTP activity between B3 and their FTP server. Note that B3 never download the full gamelog file ; it only reads the tail. So if your gameserver log file grows of 5 MB per day, then the added load will be a transfert of those 5 MB in a day
