I asked part of this question previously, but it was buried in another thread where I was trying to fix problems.
I'm currently exporting netflows from an asa and using nprobe on an evaluation basis to zmq that to ntopng. However, I'm reading the ASA's implementation of netflow isn't exactly "flow" oriented, but more based on network security events, so there's no mid-flow updates, etc. While it seems like router platforms are "best" for netflow with ntop, I don't really have one in a useful place in my network. I could however reconfigure to use a cisco switch to generate netflow data and use that. I've got a recent model cisco 3xxx series switch with ipbase licensing, which is capable of flexible netflow. Beyond the obvious differences in network visibility caused by using a different device, are there advantages to flexible netflow on the switch platforms compared to the ASA platform? Is the FNF implementation on the current 3xxx series models comparable with the implementation on router platforms, at least in terms of how "normal" the flows look to ntopng? Would there be any problems/benefits with bringing both back to ntopng? If so, would you do it with separate nprobe instance feeding a separate zmq to ntopng, or just bring it to the same probe? *This e-mail is intended solely for the addressee.
