# Python NetFlow v9 parser and UDP collector
This script is able to parse incoming UDP NetFlow packets of **NetFlow version 9**.

Version 9 is the first NetFlow version using templates.
Templates make dynamically sized and configured NetFlow data flowsets possible,
which makes the collector's job harder.

## Development environment
I have specifically written this script in combination with NetFlow exports from
