[Nut-upsdev] CPQPOWER-MIB - nearly there

[Philip Ward]

I have attempted to create cpqpowermib.h for the snmp-ups driver. We use
HP UPSs and version 2 of the firmware for their AF401A management cards
use the CPQPOWER-MIB.

I have attached my current attempt (which builds and almost works
against nut 2.4.1). Once all is working I'll send in the finished
article for consideration. This file is based on ietfmib.h.

There are a couple of issues I'd like input on. Firstly I can't seem to
get input and output voltage to work. The code looks right to me
(compared with the corresponding code in ietfmib.h) but the values are
not showing when running upsc. Perhaps a fresh pair of eyes will spot
what I have missed.

Secondly CPQPOWER-MIB does not have a "Battery Status" field in the same
sense that IETF does. In order to get around this I have used Battery
Capacity instead. This is a percentage, so I've made values above 20 as
normal, and values of 20 and below as LB. If anyone has strong feelings
regarding this, or a better idea then please reply.

Finally, there is a temperature field (upsEnvAmbientTemp) which shows
the environmental temperature. There is no field for internal
temperature. I have used this value for ups.temperature. Is this what it
is for, or should ups.temperature be left blank?
