First, know CGI - a contract between a service executable and the web server. CGI must exit 0, must write part of the http response to stdout, gets Get form input in an environment variable encoded, other env variables tell about the socket, and POST input has to be read from stdin and decoded per the information in the environment. I think stderr goes into a log file. Input data can be in many different MIME formats. Output can be in almost any MIME format, e.g., text/html, text/plain, etc. You can write a CGI service in any language, but PERL scripting was an early leader.

PERL has modules to deal with CGI inputs and to help write output, but you must know HTTP and HTML to create valid and effective documents. And of course, you need to know about application specific challenges like creating PDF output if desired.

hobbit-confreport.cgi

HOBBIT-CONFREPORT.CGI(1)				      General Commands Manual					  HOBBIT-CONFREPORT.CGI(1)

NAME

       hobbit-confreport.cgi - Xymon Configuration report

SYNOPSIS

       hobbit-confreport.cgi

DESCRIPTION

       hobbit-confreport.cgi is invoked as a CGI script via the hobbit-confreport.sh CGI wrapper.

       hobbit-confreport.cgi  provides	a  plain  HTML	(Web)  report of the Xymon configuration for a group of hosts; which hosts are included is
       determined by the hosts available on the webpage from where the CGI script is invoked.

       The configuration report include the hostnames, a list of the statuses monitored for each host, and if applicable  any  configuration  set-
       tings affecting these. Alerts that may be triggered by status changes are also included.

       The  report  is	plain  HTML  without any images included, and therefore suitable for inclusion into e-mails or other documents that may be
       accessed outside the Xymon system.

OPTIONS

       --critical
	      Report only on the statuses that are configured to show up on the Critical Systems view.

       --old-nk-config
	      Use the deprecated NK tag in bb-hosts to determine if tests appear on the Critical Systems view.

       --env=FILENAME
	      Loads the environment defined in FILENAME before executing the CGI script.

       --area=NAME
	      Load environment variables for a specific area. NB: if used, this option must appear before any --env=FILENAME option.

       --debug
	      Enables debugging output.

BUGS

       Client-side configuration done in the hobbit-clients.cfg(5) is not currently reflected in the report.

       Critical Systems view configuration is not reflected in the report.
