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 …

Measuring nProbe ElasticSearch Flow Export Performance
nProbe (via its export plugin) supports ElasticSearch flows export. Setting up nProbe for the ElasticSearch export is a breeze, it just boils down to specifying option --elastic. For example, to export NetFlow flows collected on port 2058 (--collector-port 2058)  to an ElasticSearch cluster running on localhost port 9200, one can use the following nprobe -i none -n none --collector-port 2058 --elastic "flows;nprobe-%Y.%m.%d;http://localhost:9200/_bulk" nProbe will take care of pushing a template to ElasticSearch to have IP fields properly indexed, and will also POST flows in bulk to maximize the performance.
