Visitors on subdomains register, but I can't see which subdomain they visit.

Hi all,

Just trying to get my head around this plugin and I've come up against a hurdle. I've configured the plugin as instructed - I've added a tracking code for the network admin and one for a user account I'm testing.

When I visit the test subdomain, I can see a visitor in Google Analytics realtime view, but the URL just reads "/". I had guessed it would read "/" is of no value to me.

How can I set this plugin up in such a way that I can differentiate traffic between the subdomains and as an admin know which ones actually draw traffic?
