How do I run a report for all traffic for a particular application/port?

How do I run a report for all traffic for a particular application/port?

I would like to find all sources of smtp.  We have data collected from pretty much all of our site routers, so I should have the data I need.  But I don't see a way to do this.  It looks like we have only Devices defined, a few IP groups (but what I probably need is an IP Group for RFC-1918 addresses), and nothing under CBQoS/NBAR.

Can anyone give me at least a high level HowTo for getting a report on a port?
