[Nut-upsdev] SNMP on HP UPS

[Philip Ward]

Hi,

I would like to contribute code to make the SNMP driver compatible with
HP's AF401A UPS module. It is also compatible with HP's older SNMP
modules.
It's just a new mib specification plus the necessary changes to
snmp-ups.c

Several sources have told me that these UPSs use the cpqpower.mib, but
comparing that mib at http://www.snmplink.org/cgi-bin/nd/m/Ent/H/Hewlett
%20Packard%20(HP)/%5BALL%5D%20-%20HP%20Insight%
20Management/Compaq/cpqpower.mib with the output of an snmpwalk shows
this not to be the case.
Therefore I have created af401amib.h which is just a modified copy of
ietfmib.h.

Here are the differences between ietfmib and af401amib

ups.test.result ("1.3.6.1.2.1.33.1.7.4") not supported.
battery.current ("1.3.6.1.2.1.33.1.2.6.0") not supported.
battery.temperature ("1.3.6.1.2.1.33.1.2.7.0") not supported.
output voltage is "1.3.6.1.2.1.33.1.4.4.1.2.1"
output current is "1.3.6.1.2.1.33.1.4.4.1.3.1"    

The following output levels are not supported:
    output.realpower
    output.L1-N.voltage
    output.L2-N.voltage
    output.L3-N.voltage
    output.L1.current
    output.L2.current
    output.L3.current
    output.L1.realpower
    output.L2.realpower
    output.L3.realpower
    output.L1.power.percent
    output.L2.power.percent
    output.L3.power.percent

input.frequency is "1.3.6.1.2.1.33.1.3.3.1.2.1"    
input.voltage is "1.3.6.1.2.1.33.1.3.3.1.3.1"    
input.current is "1.3.6.1.2.1.33.1.3.3.1.4.1"    

The following input levels are not supported:
    input.L1-N.voltage
    input.L2-N.voltage
    input.L3-N.voltage
    input.L1.current
    input.L2.current
    input.L3.current
    input.L1.realpower
    input.L2.realpower
    input.L3.realpower

Since the SNMP driver complains and exits if it tries to access a value
that is not supported it was necessary to completely remove upsupported
items from the specification.

I hope this code is accepted as it would mean I no longer have to build
my own nut package when a new debian version comes out.

Thanks,
