Wat is happening on my network

Hello,

I am working at a project in Amsterdam at the Ziggo Dome. This is a music hall for 16500 people.
we have there now a wireless network in place. Every thing is going fine.

the question i got was from the marketing department. They ask me if i can see what the use is of the users on the wifi network.
They are looking at a way you can seen what people are doing on a evening on the internet.
so how many people use facebook, twitter etc.

Is there a way you can manage this

All the help is appreciated
