 294                 CHECK_COUNTER has been modified to provide extensive perfdata information.
 295                 In order to do this, some modifications have been done to the code
 296                 and some constraints have been introduced.
 297
 298                 1) For the sake of simplicity of the code, perfdata information will only be
 299                  provided when the "description" field is added.
 300
 301                 2) If the counter you're going to measure is percent-based, the code will detect
 302                  the percent sign in its name and will attribute minimum (0%) and maximum (100%)
 303                  values automagically, as well the ¨%" sign to graph units.
 304
 305                 3) OTOH, if the counter is "absolute", you'll have to provide the following
 306                  the counter unit - that is, the dimensions of the counter you're getting. Examples:
 307                  pages/s, packets transferred, etc.
 308
 309                 4) If you want, you may provide the minimum and maximum values to expect. They aren't mandatory,
 310                  but once specified they MUST have the same order of magnitude and units of -w and -c; otherwise.
 311                  strange things will happen when you make graphs of your data.
