HP DL380 Custom Monitor Using cpqHealth.mib

Hello,

Hopefully someone can help here.

I'm trying to set up a custom monitor for our HP DL380 servers using: cpqHealth.mib, CpqHeTemperatureCelsius (OID = .1.3.6.1.4.1.232.6.2.6.8.1.4)
If you poll the above it returns...
"cpqHeTemperatureCelsius.0.1:39
cpqHeTemperatureCelsius.0.2:39
cpqHeTemperatureCelsius.0.3:36
cpqHeTemperatureCelsius.0.4:39
cpqHeTemperatureCelsius.0.5:31"

The MIB has 5 instances for CPU(3), IO Board, and Pwr supply.
I'd like to return a value for ONLY the I/O board, which I can do in the MIB browser by polling OID .1.3.6.1.4.1.232.6.2.6.8.1.4.0.3 (note that I added the .0.3).
The poll returns...

"cpqHeTemperatureCelsius.0.3:36"

So, although I can request ONLY this value in the MIB browser, I CANNOT set this up in a custom monitor using the OpMgr wizard. It seems it automatically adds a 0 to the end of my OID, which causes a failure.
HELP?

Thanks,
Dave
