[mrtg] MRTG not graphing correctly

look in /usr/local/groundwork/apache2/htdocs/mrtgRA/roomalert.log

Are the values you are seeing in snmpget and in the debug, showing up in the
log file?


Also, if you deleted everything in your workdir, it will take a few times of
running to get enough values to generate graphs.

Subject: [mrtg] MRTG not graphing correctly


Newbie to MRTG. I have it up and working for network statistics and its
great!  Now I'm trying to manually configure a MRTG file and having a
problem.  I'm pulling data from an AVTECH Room Alert (environment monitor)
to get temperature readings, but nothing is being graphed. At first it
graphed some very small values from 0 to 8 then after deleting the original
image files nothing will graph.  I created the file below, ran indexmaker
and added a cron job to run it every 5 min.  I'm able to do a snmpget on the
same OID's below which do return values.  Additionally, when using debug
("cfg,snpo,log") I can see that MRTG is returning the same values as the
snmpget, but still not graphing correctly.  Any advice?
