My company is running a Watchguard x750e appliance with XTM software version 11.3.5. We currently have three T1 lines for PRI and Internet services so our available bandwidth is fairly limited. I have been monitoring the bandwidth meter on my Watchguard for several days and I am noticing long periods of time when the bandwidth hits peak usage. Is it possible to view usage at the user level? i.e. if someone is streaming a Hulu video I would like to find out who it is. I tried using the Host Watch utility but it really doesn't tell me much in terms of usage and who it doing what.
Once I identify how the bandwidth is being used what is the best way to block various streaming services such as Hulu and Pandora?
I would like to use the built in Watchguard features if possible however I am open to inexpensive and/or open source solutions as well.
