Notifications during network outage

[Martin Melin]

Sure it is. The official documentation has a great section on this, which
ends with:

"By default, Nagios will notify contacts about both DOWN and UNREACHABLE
host states. As an admin/tech, you might not want to get notifications about
hosts that are UNREACHABLE. You know your network structure, and if Nagios
notifies you that your router/firewall is down, you know that everything
behind it is unreachable.

If you want to spare yourself from a flood of UNREACHABLE notifications
during network outages, you can exclude the unreachable (u) option from the
*notification_options* directive in your
host<http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html#host>definitions
and/or the
*host_notification_options* directive in your
contact<http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html#contact>definitions."
