problem in mrtg
 

hello
i have a little question to ask
can we configure mrtg per client basis
mean i am running net cable and have 40+ users and want to check each client net usage .
is it possible through mrtg
if not then what about the squid graph
and please if it is also not then tell me the best software that can do that

my requirement is graphical interface per client
waiting for reply ....
