Thoughts would really depend on your hardware specs. Most air coming out of
a server should be around 75-80. If your internal room temp is about 64 you
might be lucky and get that. It also depends on "where" your airflow is
coming from, ceiling or floor and where you have you vented tiles located.
Air flow distribution is the biggest thing to worry about before you can
even start to think about where to place your probes.

If you setup your room(s) correctly then monitoring your center overall is
best and can get even better if your server hardware can send traps if the
temp is too high.

So I guess what I am trying to say if your air flow distribution is correct
the rest will fall into place.

Since we are talking about temperature, any suggestions on which place
is best in a data center for temperature and humidity probes?
Some options that I can think of are:

1. in front of servers (all my servers take in care from the front and
push it out of the back)
2. in back of servers
3. away from the servers

With #1 I can get an estimate of the temp and humidity of the air intake
for the servers.
With #2 I can get an estimate of the temp and humidity of the air being
output by the servers.
With #3 I can get an estimate of the general temp and humidity in the
data center.

Any thoughts?

Remove the # from in front of Options[DEVICE_NAME_batt-temp].

This needs to be specified as a gauge. Otherwise, mrtg tries to
calculate a
rate of degrees per second, which you surely don't want.

Hello
After lots of tries and help from lots of very nice guys, it works but
with
very unreal illogical result for the temperature, though the real
temperature is listed when I do a ANMP walk that's my CFG

# APC UPS Basic Output Status
# CFGNAME : [DEVICE_NAME]_basic-out-status
WorkDir: c:\mrtg-data\temp
LoadMIBs: C:\mrtg-2.9.2\MIBs\apc.mib

Target[DEVICE_NAME_batt-temp]:
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:blablabla at 10
.0.1
.128
MaxBytes[DEVICE_NAME_batt-temp]: 100
Title[DEVICE_NAME_batt-temp]: DEVICE_NAME Battery Temperature
PageTop[DEVICE_NAME_batt-temp]: <H1>DEVICE_NAME Battery Temperature</H1>

#Options[DEVICE_NAME_batt-temp]: gauge, nopercent, absolute
YLegend[DEVICE_NAME_batt-temp]: Temp
Legend1[DEVICE_NAME_batt-temp]: Temperature
Legend2[DEVICE_NAME_batt-temp]: .
Legend3[DEVICE_NAME_batt-temp]: Max value per interval on graph
Legend4[DEVICE_NAME_batt-temp]: .
LegendI[DEVICE_NAME_batt-temp]: UPS Battery Temperature
LegendO[DEVICE_NAME_batt-temp]: .

these are the first few lines of the file device_name_batt-temp.log

1046730549 25 25
1046730549 0 0 0 0
1046729687 0 0 0 0
1046729400 6 6 26 26
1046729100 4 4 26 26
1046728800 0 0 0 0
1046728500 0 0 0 0

which shows that it does get the right value
Any ideas?

Thanks and best regards
