Bandwidth/network monitoring tools

Bandwidth/network monitoring tools

[Greg Cope]

Hi all,

Anyone got any suggestions for monitoring network usage by hostclient/protocol?

I am occassionally involved with debugging why our internet bandwidth
is "slow" - and I am sure I am not the only person who has been here
and I assume there are some simple tools for this sort of thing.

I am not after debugging tools like netstat, lsof, or tcpdump. 
Excellent as they are, they are too fine grained.

Ideally this would work with our iptables based firewall/router that
does DMZ as well.

Thanks,

Greg

I'm not sure how granular you want to be.  Have you looked at MRTG or
Etherape? - John

Hi,

imho the bandwidth daemon (http://bandwidthd.sourceforge.net/) is a nice tool. it generates html output just give it a try.
maybe someone knows better tools.
