Hosts are Critical

[acarlson at princeton-il.com]

Marc,

The status (of the host in Nagios) is down.

The host definition is:

define host{
         use                     linux-server            ; Name of  
host template$
                                                         ; This host  
definition $
                                                         ; in (or  
inherited by) $
         host_name               localhost
         alias                   localhost
         address                 127.0.0.1
         }

This is how it is out-of-the-box.  How would I impliment a check_command?

Thanks,

Andy
