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 linkman: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 linkman:upsd[8] servers that have been defined
|
|
in your linkman:hosts.conf[5]. If it complains about "Access to that host
|
|
is not authorized", check that file first.
