   4 /* apcupsd monitoring script
   5   Copyright April 25, 2005, Rob Kroll, rob@killerbob.ca

   7   Because I don't think I can keep anybody from doing what they want with it, nor would I want to, I'm releasing this script
   8   to the world without restrictions. There's also no warranty, implied or otherwise. If this script somehow manages to make
   9   your computer blow up, you're on your own. That said, I sincerely doubt that's even possible.
  10
  11   User-Configurable variables below:
  12       $statusfile_location       This is the location of the apcupsd.status file, as found in /etc/apcupsd/apcupsd.conf
  13                                  If this file exists, the graphical parse will be displayed.
  14       $logfile_location          This is the location of the apcupsd.events file, as found in /etc/apcupsd/apcupsd.conf
  15                                  If this file exists, it will be displayed with most recent entries first.
  16       $showloglines              By default, this script does not display the entire .events file. This is the number of
  17                                  lines to display by default. The script generates a link that enables displaying the
  18                                  entire log.
  19       $goodcolour                Default: "lightgreen". This is the HTML colour for the background of cells where things
  20                                  are good.
  21       $warncolour                Default: "yellow". This is the HTML colour for the background of cells where things are
  22                                  in need of attention.
  23       $badcolour                 Default: "red". This is the HTML colour for the background of cells where things are bad.
