The latest version of Host sFlow adds support for ULOG traffic monitoring (with ingress/egress ifIndex numbers): http://host-sflow.sourceforge.net/ Cheers, Peter

My only issue is that I can't seem to find any good software for Linux that works with multiple interfaces to generate the flow information. I've tried ndsad, nprobe, softflowd, host sflow, and ipcad without much luck. Most of the software only works on one interface (which is useless as I need to do accounting for numerous interfaces).
