SNMP - cpu core information for Sun SPARC machine

Dears,

I'm looking for getting CPU cores information of Sun machines (like: SunFire V880, Fujitsu SPARC T5120, ...) via SNMP, unfortunately i couldn't find the proper OID for that. Can anyone help me with this ?
Thanks,

It looks like you can get the model of the system and number of CPUs, but not the psrinfo sort of data from the stock SNMP agent. Apparently there is much more if you install open source net-snmp. Even so, a lot of what you get is configured text, not looking at the hardware.
