There are two spots I have found to find the more detailed info. Under Network-Wide > Traffic Analytics you can take a look at the traffic. Then by clicking on the specific type of traffic you can take a look at the user utilizing it. If you click on the user to the right of the page you will see a pie chart looking thing. Slightly above the pie graphic there are arrows to navigate between Applications, Ports, and HTTP content. If you select HTTP content you can then click show details below and a list will populate showing specific sites for that user. Alternatively if you have a specific user you are looking for/at you can locate them under Network-Wide > Clients and follow the same process. Let me know if this works for ya. 🙂
