Nagios to Monitor Specific IP data transfers

[KalistoCA]

Hi Everyone;

I'm not really new to nagios but it has been over 8 years since I last picked it up.

this is for a home based network.

What I would like to do is monitor and track data transfers between IP's

example: my sons playstation 3 connects to the EA Servers for playing FIFA 13, what I would like to do is monitor/log and display the data transfer amount as a separate item with the interface.

this really is just for amuzement more than anything else, but I can apply this logic to youtube for example so I can visualize how much data is being transfered while my daughter is watching Beiber videos.

I'm not looking for someone to spell out the solution, just point me in the right direction.

Thanks for all of your help.

cheers,
Kali

You will need a router that supports something like Cisco's NetFlow (there's also the compatible sFlow & JFlow, and probably other incompatible approaches). That will collect the information you need, but then you need some other tool to analyze and visualize it for you. Nagios has its own product for this coming out soon, NNA (Nagios Network Analyzer), currently in beta.

Rather than buy an expensive router that supports NetFlow, you could set up a Linux machine to act as a router. Installing fprobe on it will allow it to collect NetFlow data. (This would be a cheap solution, but it would also require a lot of technical skill.)
