I see. It's just not clear whether you are using pmacctd compiled
against vanilla libpcap. If this is the case, i can advice to give
a try to PF_RING. The kernel module can be configured for sampling
by passing the sample_rate

Ah - didn't realize that PF_RING could sample on it's end. I tried
PF_RING previously and actually ran into worse performance than non
PF_RING, but I didn't configure sampling.
Aha - at least I fixed this. Looks like there were

Thanks for the examples! I'm having trouble with the iptables piece
of the puzzle though. I suspect this is because I'm mirroring traffic

I'm curious: if mirroring traffic to the box, why resorting to uacctd
and iptables/etables? You have pmacctd (libpcap-based) readily available
for such scenario. With uacctd covering the case where traffic is being
cleanly routed

Hello,
Is there any documentation describing the setup required for uacctd?
I'd like to check this out, but can't quite figure out all the steps I
need to do in order to get things working.
Thanks,

Below is an example of uacctd that I'm running:
