upsimage.cgi - Man Page

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​.

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​.

For details about configuring some popular web servers to run NUT CGI programs, please see the upsset.conf(5) page​.

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​.
