quadman101, sorry for the delayed reply.
Are you currently collecting any information via NetFlow? Have you set it up already? Unfortunately, it won't give you great insight it to what is being accelerated / compressed versus regular traffic (you riverbed web interface should provide some information on this). However, for any non-accelerated portions (ie: you connection to your SP for access to the Internet) you should see a good break down of what's going across the wire.
For Riverbed specific information, take a look at these UnDPs and reports
