[Ntop] determine host with most traffic

[Gary Gatten]

A couple hours is pretty easy. I'm not in front of ntop now, but I think in the "network traffic" report one can click on the graph and the top 3 hosts will be displayed for the period selected. There is also another traffic report that color codes the top hosts during each one hour period.

Ill be in the office Tuesday and can provide the exact url's to the reports I'm thinking of.

as soon as we complete the developments we'll write some docs. For the time being you can see some examples in the python/ directory part of ntop. You basically have to scan the directories where ntop saves the RRDs, use the RRD python library to read the traffic values and sort the values using the python sort facilities.
