Hi Paolo, Sorry for the late reply, I was busy rebuilding our test lab and had to leave my Netlfow experiments aside for a while.
Thanks for the your response, I understand the constraints. I will use perf counters as an aggregator for now, it will probably add some I/O load and storage needs but all-in-all it is still better than non-aggregating solutions and - as you said - I can do the aggregation myself.
