You can get this information (although not like Sitemeter display it with the date and time of a specific request and its referrer) by doing this:
- Click "Marketing Optimization"
- Click "Marketing Campaign Results"
- Click "Referral Conversion"
You will probably want to see more than 10 entries so be sure to change that to a higher number (at the top bar).
It will show you a grouped list by domain names and the amount of referrals you got from that domain. Clicking on the little "+" sign will show you the exact referral URL from that domain.
