[mrtg] Intermittent Errors

[Nate Burke]

Greetings all,
I have been using MRTG to monitor my network traffic for many months now,
and absolutely love it.  I have just received a shipment of APC9606 web/snmp
cards for APC battery backups, and wish to use MRTG to monitor the voltages
present in the Battery units.  I have the MIB's which I wish to monitor from
the APC MIB provided with the unit.  When I first set it up in MRTG
yesterday, It would run fine the first 4 or 5 times through the cycle, then
it would start erroring out.  When I would stop and restart mrtg, it would
work for 1 or 2 cycles, then error out.  This morning, it won't run at all,
and just errors out right away.  If I use GetIf 2.2, to walk the MIB, it
retrieves the values just fine.  Thanks in advance for any help.

Nate

Here is the section of my Configuration File for the APC unit:
