 +==== Web monitoring interface (optional) ====
 +
 +The ''apcupsd'' package comes with a web-based frontend to the daemon which monitors battery status and generates graphs.  The files need to be placed in the filesystem where Apache has been configured to allow scripts to run.
 +
 +Copy the CGI scripts:
 +<code>$ cd /etc/apcupsd
 +$ sudo cp multimon.cgi upsimage.cgi upsstats.cgi /var/www/cgi-bin/</code>
 +
 +Check the status by visiting http://hpc.ilri.cgiar.org/cgi-bin/multimon.cgi
 +
 +===== Startup =====
 +Add the daemon to the default runlevels:
