There are several similar tools designed for ISP customer care centers
to help analyze network problems reported by customers.  Customer calls
with complaint, agent clicks on tool and asks customer to try what is
broken, tool analyzes traffic and guesses what's wrong.  CC agent then 
reads from the script for fixing problem X.

They tend to be expensive and are designed for point-click call center 
agents.  The back-end analysis some of these systems attempt is
impressive, even if the output is overly simplistic.  The one I'm most 
familar with was Adlex <http://www.adlex.com/> which has been purchased 
by CompuWare.  But there are several others.
