[mrtg] Issues graphing an integer value from ServerTech Power Towers

[Patrick Topping]

I am trying to graph the current load and threshold of several 
Servertech Power Towers.  Below is the output from the snmpwalk for both 
MIB OIDs:

snmpwalk -v 2c -c ubaVcj8PYF ptxl0101a-eqla3.stk 
1.3.6.1.4.1.1718.3.2.2.1.7.1.2
Sentry3-MIB::infeedLoadValue.1.2 = INTEGER: 463 hundredth Amps

snmpwalk -v 2c -c ubaVcj8PYF ptxl0101a-eqla3.stk 
1.3.6.1.4.1.1718.3.2.2.1.7.1.1
Sentry3-MIB::infeedLoadValue.1.1 = INTEGER: 338 hundredth Amps

Below is my cfg file set up:

EnableIPv6: no
WorkDir: /var/www/mrtg/rrd
Options[_]: growright,bits
LogFormat: rrdtool

LoadMIBs:  /usr/share/snmp/mibs/SENTRY3.MIB.txt

When I run mrtg with the debug options to make sure everything is 
working I get the following output with NAN/NAN values:

Any help with this would be greatly appreciated.
