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.

http://ibmonitor.sourceforge.net/

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.

HP GlancePlus if you can afford it.

sar whould also do the trick

as do netstat.

As do literally dozens and dozens of tools around the 'Net.

use the command "nload"

nload - displays the current network usage

Synopsis

nload [-a period] [-i max_scaling] [-m] [-o max_scaling] [-t interval] [-u h|H|b|B|k|K|m|M|g|G] [-U h|H|b|B|k|K|m|M|g|G] [devices]
