Error in configuration file '/usr/local/nagios/etc/objects/localhost.cfg' - Line 21 (NULL value)
   Error processing main config file!

 

***> The name of the main configuration file looks suspicious...

     Make sure you are specifying the name of the MAIN configuration file on
     the command line and not the name of another configuration file.  The
     main configuration file is typically '/usr/local/nagios/etc/nagios.cfg'

***> One or more problems was encountered while processing the config files...

     Check your configuration file(s) to ensure that they contain valid
     directives and data defintions.  If you are upgrading from a previous
     version of Nagios, you should be aware that some variables/definitions
     may have been removed or modified in this version.  Make sure to read
     the HTML documentation regarding the config files, as well as the
     'Whats New' section to find out what has changed.
