NAME

       upsimage.cgi - Image-generating helper for upsstats.cgi

SYNOPSIS

       upsimage.cgi

	   Note
	   As a CGI program, this should be invoked through your web server. If you run it from the command line, it will either complain about
	   unauthorized access or spew a PNG at you.

DESCRIPTION

       upsimage.cgi generates the graphical bars that make up the right side of the page generated by upsstats.cgi(8). These represent the current
       battery charge, utility voltage, and UPS load where available.

       The images are in PNG format, and are created by linking to Boutell's excellent gd library.

ACCESS CONTROL

       upsstats will only talk to upsd(8) servers that have been defined in your hosts.conf(5). If it complains about "Access to that host is not
       authorized", check that file first.

FILES

       hosts.conf(5)
