I'm sorry if this has been answered over and over again, but I can't seem to
find anything that will help me narrow down my trouble.  I've looked through
the FAQ's and done google searches, but nothing has come close to helping
me.  I hope someone can help me by pointing out what I've been doing wrong.
I'm using Redhat 9.0.  Any help would be great.  Thanks in advance!  

I'm trying to monitor one temperature unit.  This is what's in my mrtg.cfg
file:

####################################################################
Target[BLD47-107]: `/usr/local/nagios/libexec/mrtg_temptraxe -H 10.10.10.10
-p 1`
MaxBytes[BLD47-107]: 200
Title[BLD47-107]: Building 4, Lab 7
PageTop[BLD47-107]: <H1> Lab 107 Temperature </H1>
Options[BLD47-107]: growright,gauge,nopercent
YLegend[BLD47-107]: Deg Farenheit
ShortLegend[BLD47-107]: &nbsp;
LegendI[BLD47-107]: &nbsp;Temperature:
Legend1[BLD47-107]: Temperature
Legend3[BLD47-107]: Maximal 5 Minute Temperature
###################################################################

When I run "/usr/local/mrtg-2/bin/mrtg /var/www/html/mrtg/mrtg.cfg" I get an
error I can't figure out.  I've tried adjust the file but I still get the
error below.  The strange thing is that it appears that it's really working
because my graph is growing and the temperature is correct most of the time.

####################################################################
[root at Nagios libexec]# /usr/local/mrtg-2/bin/mrtg
/var/www/html/mrtg/mrtg.cfg
WARNING: Problem with External get '/usr/local/nagios/libexec/mrtg_temptraxe

(running the command it's trying to run from the command line)

[root at Nagios html]# /usr/local/nagios/libexec/mrtg_temptraxe -H
129.238.159.44 -p 1
70
#####################################################################

In the FAQ's it says that this is due to outputs given in fraction, white
space or not output.  Well, I've checked all of that and I do get a whole
number and there is not white space.  I'm stumped.  Has anyone had this
problem?  Any help would be great.

Mike
