Hardware requirements

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 NFSEN as a free alternative, with extensions to build reports by protocols and directions.

You shall need a computer with VEOS 8.6 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.

Do not install NFSEN on DPI server. Making reports require considerable CPU resources. This may lead to negative impact on DPI performance.
