I don't use it but it appears that you must have host/service retention
enabled as well, including adding the retain_status_information and
retain_nonstatus_information to your host/service definitions or
templates.

Using '/etc/init.d/nagios reload' or sending a HUP signal to the master
nagios daemon will cause it to reload the config w/o restarting. With
the settings above enabled then it should retain the scheduling queue
and pre-reload status information for hosts and services.

Personally, we just run a config verification (nagios -v) when adding
hosts and restart each night to have the changes enabled.
