I was given a similar mandate for as with this task but this time around I did have a lot of historical data already by means of netflow data collected by NFDUMP a high-performance open source netflow collector. The only problem the data as such could not be used for my purpose without a bit of massaging. And here is how I did it.

Goal

Create a graph from collected netflow data in the NFDUMP format with a precision of one second.

Note: For lower precision graphs the NfSen visualization package should suffice.
