Production Flow collector tool is in my shopping list but mostly very expensive to push the cart to the register. Then, by binding multiple tools to make a visualizing web tool internally. I would like to introduce actual structures and difficulties I bumped into(especially IPv6 address translation was painful) as this was the first time to build a tool like this, and things yet to be visualized.
The things I used: sfcapd, nfdump, SNMP, PeeringDB2.0 API, RRDTool, etc.
