Adrian , thanks for your response.
About sampling ... Im not sure what is it but im running the fprobe just
with the line:
/usr/local/sbin/fprobe -i eth3 -fip -n7 172.24.3.12:9995
Which in a case o a traffic bellow than 1gbps works great.
In my case the message you are describing "Sequence errors or bad packets"
Apears many times in the collector log file, so there is some problem ,but;
How can I confirm if the problem is on the nfcapd or the fprobe side ?
Can I modify on something on any side to properly export more than
1.4Gbps ?
Both machine where they are running are very powerfull machines.
I can provide more info
Thanks in advance!!!
Leo.

If you're using sampling you should see differences between netflow
traffic and real traffic. If not, check that:
1. you're not losing UDP packets - if you lose packets you should see
something like this:
Dec 4 09:35:00 localhost nfcapd[13268]: Ident: 'MyRouter' Flows:
11763, Packets: 930064, Bytes: 731126982, Sequence Errors: 0, Bad
Packets: 0
Sequence errors or bad packets will indicate something's wrong on the
network side.
2. your router has enough capacity (TCAM memory) to export all the flows
If you get errors in your router's log that TCAM memory is nearly
exhausted, then the router will stop producing flows for a while and
you get those drops at higher traffic.

Hi , guys.
It is very strange but , my nfsen is showing a maximun traffic
value of
1.2 gbps when the traffic showed on cacti is 2gbps(also meassured
on the
router).
Traffic shape is ok , minimun values mathes on both tools.
Any ideas about it ? Is there something to tune on fprobe, nfcapd or
nfsen ?

Leandro.
