UPSIMAGE.CGI(8) NUT Manual UPSIMAGE.CGI(8) 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 unau- thorized 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 ex- cellent gd library. For details about configuring some popular web servers to run NUT CGI pro- grams, please see the upsset.conf(5) page. 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 autho- rized", check that file first.
