OID's for physical- and used memory on W2K

[gosuc2000]

Hello Gurus,

I'd like to poll the OID's for the overall phys. memory
and the used memory on a Windows2000 System from my Linux Monitoringstation. The values should be plotted via MRTG.

I can find the amount of phys. memory, but not the memory in use.

I'm just about to learn SNMP, so I'd apreciate any help.

Thanks in advance,

Fred
