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)
