bandwidth monitoring

[Cody Baker]

Ntop is a good tool, we use it, but my experience is that it's buggy at
best and downright unusable at times. Also, it's data isn't very
portable. I'd recommend using SNMP data from a managed switch. If that's
not an option the you might consider using SNMP data from your router or
worst case directly from each individual server. In terms of software
this generally means net-snmp connected to rrdtool or mrtg. I googled
real quick and
http://www.openxtra.co.uk/resource-center/open_source_network_monitoring.php
seems to provide a quick front en to these tools.

Thank You,
