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:

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

This is my oid for temp I graph it with 5 remote probes.  Albert Stadler

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?

WorkDir: /var/www/html/mrtg
Title[^]: CO APC 1400 in top of main server rack (degrees Fahrenheit)
