It might be overkill for a single box, but tools like OpenNMS will collect this info from any number of targets via snmp and let you graph the history up to a year back.
And there are other trend graphing applications like Cacti that will give you the same sort of historical data. Data points are also collected via SNMP, but if you write custom scripts Cacti can use you're not limited to just things exported via SNMP.
[But extensibility via scripts is common to most open source software and exporting data points via SNMP is a best practice.]
Opennms is very extensible too - and includes support for collecting metrics via wmi, xml, jmx, etc. But it is a big framework and fairly complicated to extend (but a lot works out of the box after a simple yum install). Something like collectd would be more lightweight.
