+ provided when the "description" field is added.
+
+ 2) If the counter you're going to measure is percent-based, the code will detect
+ the percent sign in its name and will attribute minimum (0%) and maximum (100%)
+ values automagically, as well the ¨%" sign to graph units.
+
+ 3) OTOH, if the counter is "absolute", you'll have to provide the following
+ the counter unit - that is, the dimensions of the counter you're getting. Examples:
+ pages/s, packets transferred, etc.
+
+ 4) If you want, you may provide the minimum and maximum values to expect. They aren't mandatory,
+ but once specified they MUST have the same order of magnitude and units of -w and -c; otherwise.
+ strange things will happen when you make graphs of your data.
