Monitor the time users spent on the internet

[jpab]

Hi,

I would like to monitor the time that the users spend on the internet. I need to create a report for management showing the users and the time spends per day/week/month.
Is this possible?

Thanks

No it isn't possible, and to be frank, any product that claims to have this functionality is lying to you. The only realistic measure we have on a network to determine when a web event fires, is when it fires itself. There is no way to realistically measure how long a user was looking at a given resource, when that resource only lives within the context of their browser.

You can infer somethings if you see a history looking at a given site, but because so many sites have dynamic refreshes, I can start up msn.com and make it look like I've been surfing the web all day and all I did was have a background tab open!
