Kevin,

I did what you suggested, now I can one hostname and underneath I can see
services as ping_1, ping_2,..... to monitor other ips in the same
host/device. this looks kool. But I tried to shut down one server that
relates to the IP ( i added my test server IP here to check), I can still
see that the host's IP is up and running in Nagios. And when I down the
actual hostname ie Prod-firewall all the services related to that host were
down.

It looks the solution you gave me is not working. Any idea?

Thanks
