I also found the Linux/GNU implementation of of sar quite useful to this end.
sar is, at least under RHEL, part of the sysstat RPM which usually doesn't get installed per default.

$ rpm -q --qf "%{release}\n" redhat-release
5.6.0.3

$ rpm -qf $(which sar)
sysstat-7.0.2-3.el5_5.1


e.g. to get traffic stats per NIC every five secs

$ sar -n DEV 5 0


the same but for error stats

$ sar -n EDEV 5 0

I kinda like "ibmonitor" which is just a pearl script.

Great if you wan't to have a look at current throughput and it will list for all your interfaces.

If you leave it on it will give you avg until you close it.

nload - displays the current network usage

Synopsis
