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
