Try adding gauge to the options line. The temperature and humidity counters do not increase over time so the difference between reads will be zero or close to zero

Thank you Toby and everyone else, it.s a nice little program. :) Now I have been asked to integrate an AKCP Sensor Probe into the mess. Anyway what these probes do is report on temperature and humidity. What I am trying to do is get MRTG to trend out this data. My humidity data will always be presented as a percentage (100% being the air is saturated with water, 0% means there is no water in the air). Temperature will be in degrees Fahrenheit, which is kind of nice, we don't need to worry about temperature ever dropping below 0. So what I have is the following MRTG configuration file (my supervisor wants humidity and temperature on two separate plots). # Autogenerated MRTG config file, created by /home/scripts/gencfg.sh WorkDir: /home/mrtg/Temperature LogDir: /home/mrtg/Temperature/logs LoadMIBs: /home/mrtg/sp.mib Refresh: 300 RunAsDaemon: yes Interval: 5 Options[_]: noinfo, growright MaxBytes[_]: 150 YLegend[_]: Environmental Conditions WithPeak[_]: dwmy Target[tor_computer_room-Temp]: 1.3.6.1.4.1.3854.1.2.2.1.16.1.3.0&1.3.6.1.4.1.3854.1.2. 2.1.16.1.3.0:<SNMP READ COMMUNITY>@tor-cr-temp.domain.tld Title[tor_computer_room-Temp]: Temperature PageTop[tor_computer_room-Temp]: <H1>Temperature -- tor_computer_room</H1> <TABLE> <TR><TD>Maintainer:</TD> <TD>Field Support.</TD></TR> <TR><TD>Description:</TD><TD> Temperature</TD></TR> <TR><TD>DNS:</TD> <TD>tor-cr-temp.mlmc.com()</TD></TR> </TABLE> Target[tor_computer_room-Humid]: 1.3.6.1.4.1.3854.1.2.2.1.17.1.3.0&1.3.6.1.4.1.3854.1.2 .2.1.17.1.3.0:<SNMP READ COMMUNITY>@tor-cr-temp.domain.tld Title[tor_computer_room-Humid]: Humidity PageTop[tor_computer_room-Humid]: <H1>Humidity -- tor_computer_room</H1> <TABLE> <TR><TD>Maintainer:</TD> <TD>Field Support.</TD></TR> <TR><TD>Description:</TD><TD> Humidity</TD></TR> <TR><TD>DNS:</TD> <TD>tor-cr-temp.mlmc.com()</TD></TR> </TABLE> Only there is a problem with these graphs, after running mrtg for about an hour I have the following log file: $ more tor_computer_room-temp.log 1120596048 72 72 1120596048 0 0 0 0 1120595747 0 0 0 0 . Here is an earlier more: $ more tor_computer_room-temp.log 1120595447 72 72 1120595447 0 0 0 0 1120595147 0 0 0 0 . So its not as if I've been too impatient or my SNMP query is incorrect, the temperature in the Toronto Computer Room is indeed 72 degrees (about 20 degrees Celsius). MRTG is not returning any errors when I run the cfg file so I am at a loss, what could I be doing wrong? Just in case this is at all helpful I am submitting an SNMP get of temperature and humidity taken from the MRTG server: $snmpget -v 1 -c <SNMP READ COMMUNITY> tor-cr-temp 1.3.6.1.4.1.3854.1.2.2.1.16.1.3.0 SNMPv2-SMI::enterprises.3854.1.2.2.1.16.1.3.0 = INTEGER: 72 $ snmpget -v 1 -c <SNMP READ COMMUNITY> tor-cr-temp 1.3.6.1.4.1.3854.1.2.2.1.17.1.3.0 SNMPv2-SMI::enterprises.3854.1.2.2.1.17.1.3.0 = INTEGER: 43 Any help would be appricated.
