Thanks for the suggestion. I am looking into it now.
Currently, I use Cacti to graph the data coming from my switches. Do you know if that will that work with any of these switches?
Cacti will work for port based monitoring, it won't work for flow-based monitoring though.

ntop would probably be the main "free" flow based monitor, though there are some really really nice commercial products.
Inmon has a couple free tools as well sflowtrend, and another command line tool which can dump the contents of sflow data to STDOUT for parsing by a script.

Can one setup a Linux server to offer sflow? If the Linux host can run sflow, then it's easy to capture the bandwidth usage on the host? I'm sitting with the same problem, and rely on snmpd on each VPS, but this isn't ideal - especially if clients disable snmpd
