racluster -M rmon: how to use it?

Hi,

I have some problem to unterstand how racluster -M rmon (should) work. I
want to plot inbound/outbound traffic - not src/dst traffic.

I'm using something like this:

racluster -M rmon -r argus.log - \
   srcid elibridge_dmz and src host 172.17.132.81 \
   and dst host 172.17.130.2 and tcp dst port 80 and tcp src port 1415

The output is:

2007-02-21 08:15:27.658658 tcp 172.17.132.81.1415 -> 172.17.130.2.www \
                            9       13         1055        11936   FIN
2007-02-21 08:15:27.658658 tcp 172.17.130.2.www  -> 172.17.132.81.1415 \
                           13        9        11936         1055   FIN

The flow is duplicated. Okay, if RMON works this way, how can I filter out
inbound and outbound traffic?

A simple 'ragraph bytes -M 10s -M rmon ...' shows a symetric graph with
inbound = src+dst = outbound. 

Is there a way to show what is coming in/going out related to the
interface?
