[Discuss] Network monitoring tool recommendation

[darose at darose.net (David Rosenstrauch)]

???  I use Nagios extensively on our system to monitor for uptime on 
machines/daemons, and alert us when something breaks.  But I'm not aware 
of it having the capability to show cumulative network usage, by remote 
host, across a span of time, for every machine on a network.  If it 
does, could you point me to which plugin one might use for that?

Thanks,

DR
