aliased nics should work fine via snmp,  so try mrtg.  http://oss.oetiker.ch/mrtg/

Just setup netsnmp so that it answers  to whichever host is querying it (it can be itself if u want). Cacti ins't too bad, and it's nice in that it is relatively easy to make custom graphs to graph just about anything.   Create a VM to run it (or mrtg or wahtever) and once you start graphing shit,  you'll start graphing all sorts of stuff. (how much mail comes in.out,  how much is spam and caught, etc...

Hello All,
  I would like to know what others are using (I can't be the only one)
in Linux to monitor network traffic/usage. It appears that I'm having a
problem because of aliased nics (eth0:0, eth0:1, etc). I looked into
cacti, way more than I want and not sure it will handle what I have
anyway with the aliased nics. I looked a few in the repos of Ubuntu,
nload would be PERFECT but it won't do the aliased nics. The aliased
nics looks like that would be a problem for just about anything so
that's why I'm throwing this out there. In a nut shell, what I would
like is something real simple like nload to put on my router which has
2 physical nics and 9 aliased ones so I can watch all the
incoming/outgoing per nic. My router is a pc running Ubuntu Gutsy with
Shorewall. I was going to look into nagios but that looks as complex as
cacti and I don't want to have a freaking web server running just to
check network statistics. Any thoughts? I'm sure somebody out there has
dealt with this and I'd rather keep the monitoring on the router,
instead of the individual boxes. TIA, Peter
