Whoops!
Error: Could not open CGI config file '/etc/nagios/cgi.cfg' for reading!
Here are some things you should check in order to resolve this error:
Make sure you've installed a CGI config file in its proper location. See the error message about for details on where the CGI is expecting to find the configuration file. A sample CGI configuration file (named cgi.cfg) can be found in the sample-config/ subdirectory of the Nagios source code distribution.
Make sure the user your web server is running as has permission to read the CGI config file.
Make sure you read the documentation on installing and configuring Nagios thoroughly before continuing. If all else fails, try sending a message to one of the mailing lists. More information can be found at http://www.nagios.org.
