[mrtg] Solution--temp/humidity probes on APC UPS's

[John York]

I stole this config from someone on this mailing list a few years ago.
It works great on my old AP9617 management interfaces, but did not work
on a new AP9619 I just got.  The problem may have been firmware version
rather than 9617 vs 9619--my 9617's are a v1 variant and the 9619 is
v3.4.
OLD VERSION

I asked APC support and got this very helpful response:
The correct OID for the temperature monitoring probe on the AP9619 card
is
.iso.org.dod.internet.private.enterprises.apc.products.hardware.environm
entalMonitor.integrated.iemStatus.iemStatusProbesTable.iemStatusProbesEn
try.iemStatusProbeCurrentTemp (numerically
.1.3.6.1.4.1.318.1.1.10.2.3.2.1.4). This OID will return "The current
temperature reading from the probe displayed  in the units shown in the
'iemStatusProbeTempUnits' OID (Celsius or Fahrenheit)."

So, with that and a couple of tries with snmpwalk from Net-SNMP
(http://net-snmp.sourceforge.net/ can't imagine doing this without
Net-SNMP--thanks guys!) here's a new, working version:
Target[G_APC_temp_humid]:1.3.6.1.4.1.318.1.1.10.2.3.2.1.4.1&1.3.6.1.4.1.
