RzKFlow is an easy to use software to collect and present *NetFlow records sent from switches or routers.
RzKFlow aggregates the received records for a given interval of time and until midnight. The resulting communication matrices can be stored in well linked web pages and/or CSV files. RzKFlow has an interface for SQL export (MSQL server, oracle,...)
You can see how many frames and how many bytes are exchanged between the stations (IP addresses), the IP networks, the ports on the network and the autonomous systems.
