[mrtg] avoid graphing zeros from Powerware

Hi all,

I am monitoring a Powerware UPS 9170, which every once in a while, is giving us 
bad reads for some reason. It's returning zeros and passing them to MRTG, which 
makes ugly graphs and setting alarm thresholds difficult. We are certain that 
the zeros are caused by the UPS since looking in the powerware web based 
interface data logs confirms it. It could be the firmware version of the network 
card in the Powerware, or just a bad network card, or something deeper in the 

Nevertheless, I was wondering if anyone had this problem before or if you would 
know how I could avoid graphing these zeros being passed on to MRTG?

Any help is appreciated.
