It contain two steps, one is sitesummary gathering information and
storing it in /var/lib/sitesummary/entries/, and the next is generating
nagios setup and storing it in
/var/lib/sitesummary/nagios-generated.cfg.  This file is activated by
using /etc/nagios3/sitesummary.cfg as the Nagios setup.

I'm not quite sure if such fine graded setup is easy to do, but
notifications can be adjusted in
/etc/nagios3/sitesummary-template-contacts.cfg.

This would be done by removing obsolete entries from
/var/lib/sitesummary/entries/.  You can use
'/usr/lib/sitesummary/agesinceseen-summary -l' to find the entries that
did not report in recently.

Yes.

I suspect a good way is to make sure cfg_dir is active in
/etc/nagios3/sitesummary.cfg, and add the configuration in
/etc/nagios3/conf.d/.  Or you can just create a new file and list it in
sitesummary.cfg with cfg_file.
