First of all ensure you are making use of the 'parent' directive for hosts that way if you lose a network segment you will only ever get an alert from the top level host. More on that can be found here: http://nagios.sourceforge.net/docs/3_0/ ... ility.html (for XI there is a little box labelled parents in the host config menu).

Second of all ensure that your hosts and services have a reasonable value set for the 'notification_interval' and 'max_check_attempts' directives.

Third make sure you are only getting notifications for the level of alerting you need with 'notification_options' for hosts and services, same deal with the 'host_notification_options' and 'service_notification_options' for contact definitions.

If you are getting flooded with emails with only 100 hosts then at least some of these options are going to be configured way off base.
