+DPI exports statistics on traffic volumes (considering protocols and directions or autonomous systems) in a standard format netflow5. Therefore you can use any netflow collector and any tools to analyse netflow. We suggest to install  [[http://nfsen.sourceforge.net|NFSEN]] as a free alternative, with extensions to build reports by protocols and directions.
+You shall need a computer with [[en:veos:installation|VEOS]] or higher installed. The required disk space is from 250 MB to 1.5 GB per each day. It depends on configuration. The computer must have at least 1 GB of RAM.
+<note important>Do not install NFSEN on DPI server. Making reports require considerable CPU resources. This may lead to negative impact on DPI performance.</note>
