We have Netflow Traffic Anayliser installed and it is monitoring all the devices and their interfaces within out network.
We can get real-time bandwidth usage for our WAN circuits but I can seem to produce a graph for usage over a longer period (e.g 7 days). How can you do this?
If I use the report menu and selct historical graph the report is blank. All devices are presetning realtime transmit and recieve.
