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)
