Should be useful when I extend our Nagios monitoring to include snmp data. We're using Nagios extensively, but it doesn't seem suited to the sort of load graphing we need for our CPU cores - or if it is it's a side of Nagios I'm unfamiliar with (which could be, it's nicely
extensible).
Take a look at ganglia - http://ganglia.sourceforge.net/
This may do what you need.
