I just checked the config.txt :-)
The keyword absoulute means that mrtg should display a value d(val)/dt
where d(val) is read directly and d(val)/dt is d(val) divided by the time
passed since last read.
The gauge keyword means that mrtg should should display val directly.
I suppose you should erase the absolute keyword then, since the current
number of users or the current number of used/unused filedescriptors are
not timely derivative quantities.
