Not a direct openwrt question as such; however I'm looking to make use of softflow, and am wondering what my options are in terms of open/free stacks to process netflow flows. I can find a lot of half finished software on the internet, so really looking for particular examples of what people here are using [as I see a number of people mention softflow as something they are using].
I'm looking for top-N traffic flows, breakdown by traffic type (with some customisation, perhaps by endpoint list - as a lot of ones I've seen would blanket categorize a large amount of traffic as 'web' related), devices/IPs and so on. Ideally if it had a neat way of doing geographical visualization that would be golden.
