How to sniff packets in GWT?

Question

I'm looking for a way to sniff packets in GWT or is there any other way to perform this task. I want to show a tree map of the incoming packets based on their size . One way which I thought is to use a cmd line packet sniffing tool which would output the details to a file, which could be read from GWT and then use that to display treemap.

After doing some research and switching back to this project, One of the simplest way to do is with the help of a tool which could generate the the text file, which could be imported in the GWT code. For e.g. tcpdump could be used on Linux and once you have the output redirect it to a file, read that file in the code and then use that information in GWT code
