OK I tried to set up my first one today - testing the local host http from the sample provided on the page. Here is what I did.

define command{
        command_name    restart-httpd
        command_line    /usr/lib/nagios/plugins/eventhandlers/restart-httpd  $SERVICESTATE$ $SERVICESTATETYPE$ $SERVICEATTEMPT$
        }

Here is the services - not sure if this is correct.

# httpd-restart
define service{
 use                            generic-service

 host_name                      localhost
 service_description            HTTPD
 is_volatile                    0
 check_period                   24x7
 max_check_attempts             4
 normal_check_interval          1
 retry_check_interval           1
 event_handler                  restart-httpd
 contact_groups                 bssadmins
 notification_interval          120
 notification_period            24x7
 notification_options           w,u,c,r
 check_command                  check_ntp
}

I used the sameple script they provided: http://nagios.sourceforge.net/docs/2_0/eventhandlers.html

Now on the web interface it will say local host HTTPD: NTP CRITICAL: No response from NTP server.

So I am not sure why this was running when httpd did not go down and why I am getting a NTP error - I am sure things are set up wrong - just need to know what to change to test this out.
