/* apcupsd monitoring script
Copyright April 25, 2005, Rob Kroll, rob@killerbob.ca
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
to the world without restrictions. There's also no warranty, implied or otherwise. If this script somehow manages to make
your computer blow up, you're on your own. That said, I sincerely doubt that's even possible.
User-Configurable variables below:
$statusfile_location This is the location of the apcupsd.status file, as found in /etc/apcupsd/apcupsd.conf
If this file exists, the graphical parse will be displayed.
$logfile_location This is the location of the apcupsd.events file, as found in /etc/apcupsd/apcupsd.conf
If this file exists, it will be displayed with most recent entries first.
$showloglines By default, this script does not display the entire .events file. This is the number of
lines to display by default. The script generates a link that enables displaying the
entire log.
$goodcolour Default: "lightgreen". This is the HTML colour for the background of cells where things
are good.
$warncolour Default: "yellow". This is the HTML colour for the background of cells where things are
in need of attention.
$badcolour Default: "red". This is the HTML colour for the background of cells where things are bad.
*/

$logfile_location = "/var/log/apcupsd.events";

/*
There are no more user-configurable variables beyond this point. You're welcome to browse the code, and submit any bugfixes you
find. If you don't know much about coding, it can be educational, but you probably don't need to read further.
