NetFlow Collection Performance Using ntopng and nProbe
Introduction ntopng, in combination with nProbe, can be used to collect NetFlow. Their use for NetFlow collection is described in detail here. In this post we measure the performance of nProbe and ntopng when used together to collect, analyze, and dump NetFlow data. The idea is to provide performance figures useful to understand the maximum rate at which NetFlow can be processed without loss of data. Before giving the actual figures, it is worth discussing briefly the most relevant unit of measure that will be used, i.e., the number of …
