See the Nagios documentation (http://www.nagios.org/documentation/) for configuring the upstream
server:
The section entitled Distributed Monitoring steps through what you need to do to configure NSCA on the
upstream server (under Central Server Configuration)
NRPE Documentation has recently been added which steps through configuring NRPE on the upstream
server http://nagios.sourceforge.net/docs/nrpe/NRPE.pdf
At this stage, Nagios at the upstream monitoring server has been configured, and individual serial port and
network host connections on the console server configured for Nagios monitoring. If NSCA is enabled,
each selected check will be executed once over the period of the check interval. If NRPE is enabled, the
upstream server will be able to request status updates under its own scheduling.
