The location of nagios.cfg is hard coded into the binary at compile =
time.

The daemon has no need to know where the CGI's are.

The daemon knows the location of each specific plugin from the =

None that I know of. You could auto-search the common locations based on =
distributions (/usr/local/nagios/etc; /etc/nagios; others?) and/or =
confirm with the person running your script.

There are several macros that you are interested in that are available =
(http://nagios.sourceforge.net/docs/3_0/ ... configfile) =
that could be made available as environment macros but I believe that =
they are only visible to programs launched by the nagios daemon itself =
(plugins, notifications, etc). su to the nagios user and 'echo =
$NAGIOS_MAINCONFIGFILE' to test (assuming you've enable macros as =
environment variables in nagios.cfg).
