Try gauge then. Treat the values gathered from target as 'current status' measurements and not as ever incrementing counters. This would be useful to monitor things like disk space, processor load, temperature, and the like ...
In the absence of 'gauge' or 'absolute' options, MRTG treats variables as a counters and calculates the difference between the current and the previous value and divides that by the elapsed time between the last two readings to get the value to be plotted. ________________________________________ From: [email protected] [[email protected]] On Behalf Of John [[email protected]] Sent: Monday, January 19, 2009 11:15 PM To: Steve Shipway Cc: '[email protected]' Subject: Re: [mrtg] Config file help Steve Shipway wrote: > What do these values represent? > > So, is this a count of the total time spent on battery (ever)?

The second output is always 0, the script outputs a 0 just in case the "noo" option was missed. The third output will be the current up time when I get it fixed. The forth output is the device name. I don't think I want the gauge option, I want to count how many seconds on battery from the last power failure, not from last restart. Hopefully they're not the same. I have tried the absolute option but that got me to same place, all zeros in my log file.
