Hi all, I have a bsd box as a router, with 4 vlan interfaces. I started collecting flow data with softflowd and analyze them (in a separate machine) with nfsen, but softflowd is taking too much cpu (for the busiest interface up to 20%), so i tried to switch ONE interface to ng_netflow. I configured the same as the man page, but results are... odd. Measure are wrong. I mean, graphs collected from softflowd show the right amounts of packet/flows/data, the ones collected with ng_netflow are wrong. packets and flows are lower then expected, traffic is MUCH LOWER than expected (1/10). Any hint to debug or anyone with similar experience? Thank you -- Cris, member of G.U.F.I Italian FreeBSD User Group http://www.gufi.org/
