>The main purpose of Nagios is to monitor services that run on or are
>provided by physical hosts or devices on your network. It should be
>obvious that if a host or device on your network goes down, all services
>that it offers will also go down with it. Similarly, if a host becomes
>unreachable, Nagios will not be able to monitor the services associated
>with that host.

>Nagios recognizes this fact and attempts to check for such a scenario
>when there are problems with a service. Whenever a service check results
>in a non-OK status level, Nagios will attempt to check and see if the
>host that the service is running on is "alive". Typically this is done
>by pinging the host and seeing if any response is received. If the host
>check commmand returns a non-OK state, Nagios assumes that there is a
>problem with the host. In this situation Nagios will "silence" all
>potential alerts for services running on the host and just notify the
>appropriate contacts that the host is down or unreachable. If the host
>check command returns an OK state, Nagios will recognize that the host
>is alive and will send out an alert for the service that is
>misbehaving."

>Since you've disabled host notifications, no-one is notified.
