If you are looking for something that can do remote monitoring and can
live with a relatively rough granualarity (say every minute or every
5 minutes), you could probably build something up from the ucd-snmp
package from the NetBSD package collection, and perhaps mrtg (also from
the package collection) to graph the history.  I don't know of anything
"off the shelf".
