Thats the issue, I am using a SySymmetra 16000 
 
Firmware Revision: 
260.128.I

For some reason, I get no answer when I query that:
 
What firmware is in your UPS, Albert?
and, are you using the Smart UPS 1400 and 3000?
 
details:
 
It appears to be in the apc.mib, not the pwrchute.mib
 
[root at acslinux root]# snmptranslate -m /usr/share/snmp/mibs/apc.mib=
1.3.6.1.4.1.318.1.1.2.1.1.0       =20
PowerNet-MIB::mUpsEnvironAmbientTemperature.0
(gets an answer)
 
[root at acslinux root]# snmptranslate -m
/usr/share/snmp/mibs/pwrchute.mib=
1.3.6.1.4.1.318.1.1.2.1.1.0             =20
APCUPS-MIB::products.1.2.1.1.0
(can't quite figure it out)
 
So, export the MIB variable:
[root at acslinux root]# export MIBS=3D/usr/share/snmp/mibs/apc.mib=20
 
Now, do some gets
 
[root at acslinux root]# snmpget -v 1 -c comst=
host 1.3.6.1.4.1.318.1.1.2.1.1.0                  =20
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: PowerNet-MIB::mUpsEnvironAmbientTemperature.0
 
and
 
[root at acslinux root]#=20
PowerNet-MIB::mUpsEnvironAmbientTemperature.0
[root at acslinux root]# snmpget -v 1 -c comst host=
mUpsEnvironAmbientTemperature.0              =20
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: PowerNet-MIB::mUpsEnvironAmbientTemperature.0
 
and
 
[root at acslinux root]# snmpget -v 1 -c comst host=
mUpsEnvironRelativeHumidity.0                            =20
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: PowerNet-MIB::mUpsEnvironRelativeHumidity.0

 
 
MRTG doesn't like this either:
 
SNMP Error:

  error status: noSuchName

Any ideas on why the UPS doesn't respond to these values?

Thanks for the corrected formula-
 
the OIDS that Albert gave are for time-ticks, according to snmpwalk..
 
Does anyone have the OID for ambient temp, as opposed to internal
battery=3D
temp (listed below in my config)

Hi everyone-

I have two requests:

1.
Does anyone have the OID for how to get the temp/humidity
from the available external probe?

This config is for the battery temp of the UPS

2.
One other thing is that this is not doing the math right -
the snmpwalk returns
PowerNet-MIB::upsAdvBatteryTemperature.0 =3D3D Gauge32: 29

One formula using Fahrenheit on the right is: (C*1.8)+32=3D3DF
or
Target[apca1400]:
(.1.3.6.1.4.1.318.1.1.1.2.2.2.0&1.3.6.1.4.1.318.1.1.1.2.2.2.0:commstr at host
* 1.8) =3D3D 32

that doesn't work for MRTG though...

Any other ideas on how to lay out the formula so that it's correct and
right for MRTG as well?
