After upgrading FastNetMon community version from 1.1.4 to 1.1.9 there is a huge difference in incoming traffic counters. The outgoing traffic counters seem to be correct and are the same as before the upgrade. The incoming ones are now about 20% too high, across all hosts, networks and total counters, for both PPS and BPS.
I am using sampled Netflow with a sample ratio of 1024, with both v5 and v9 packets coming from Cisco and Juniper routers respectively.
Anyone have any idea what is going on or have experienced something similar?
