This host template for Windows SNMP was created by Dan MacDonald, and modified slightly by myself. It takes care of CPU use, and disk space - but watch out with this, because inserting USB devices will potentially cause re-enumeration of the devices, requiring a re-generation of the configuration file.

Possible improvements: The code should detect >1 CPU and then define a routers2 combination graph over the top of them and hide the individual CPU graphs. Currently, it just produces multiple CPU graphs.
