I'm using mrtg to graph the data from my AVTech Rooomalert 24E. It's taken some effort to get it functional, but I've still one issue remaining that I just can't figure out. I've found similar references to my problem around the 'net but never a definitive answer. Hoping someone here can lend a hand.
The temperature sensor returns the temp using four integers. So, a log entry of say, 2010, is actually 20.10 degrees Celsius. Unfortunately, mrtg seems rather keen on maintaining the scale in the thousands. What I need in effect is to divide all numbers by 100...or so I thought. I finally figured out that I could divide the Target / 100 which does cut down the size but I lose all precision. My log data goes from 2010 to just 20. Graphs certainly look nicer that way...I mean 2010 C *is* a bit on the warm side for a machine room, eh ;-) but ultimately, that's just not what I want. What I want is to have mrtg interpret the 4 integers as a proper temperature reading incorporating the decimal and maintaining the precision. I found this site indicating to me that it is entirely possible - http:// windmere.org/mrtg/alert/ - I'd like this exactly, but just can't figure it out. So, the question is how do I get my mrtg graphs to format properly with a decimal. Thanks a million.
