How do i bind a directory for being counted on a domain's traffic

[Domainer]

Hello.

I want to ask how i can bind a directory that i have installed game servers to a domain, so i can see what traffic it consumes.

For example my domain's path is:

/var/www/vhsosts/foo.com

Statistics report counts only the httpdocs folder's traffic and the e-mails. I have the game servers installed in /var/www/vhsosts/foo.com/games.

So how i can have this directory's traffic to be showed on domain's traffic report through plesk ?
[Traffic goes through ports like 27100,271001 and etc for each game server, and through getting web files with wget command from ssh]

Thank you very much.
