Try a look into your command definitions. These commands call the 
plugins. Sometimes there are macros used in these commands, macros are 
definded in resources.cfg file.

So make sure, that the plugin is really aviable.

i give you a short example:

define service {
use                            generic-service
host_name                      <host>
service_description            PING
check_command                  check-host-alive
contact_groups                 <group>
}

So the command is check-host-alive . So we look an this command.

define command {
command_name                   check-host-alive
command_line                   $USER1$/check_ping -H $HOSTADDRESS$ -w 
3000.0,80%
  -c 5000.0,100% -p 1
}

There we see, that a plugin named check_ping is called. But where should 
that plugin be located? We have to examine resources.cfg:


# Sets $USER1$ to be the path to the plugins
$USER1$=/usr/local/libexec/nagios

So we know: The plugin should be at /usr/local/libexec/nagios/check_ping

So, try to verify, that your plugins are properly installed and the 
references are correct. Also check, that these plugins can be executed 
by your nagios user.
