10.3.6 Configure the upstream Nagios monitoring host
Refer to the Nagios documentation (http://www.nagios.org/docs/) 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 was recently added that 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 is configured, and individual serial port and
network host connections on the console server are 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, then the upstream server will be able to request status updates under its own scheduling.
10.4 Advanced Distributed Monitoring Configuration
10.4.1 Sample Nagios configuration
An example configuration for Nagios is listed below. It shows how to set up a remote Console server to
monitor a single host, with both network and serial connections. For each check it has two
configurations, one each for NRPE and NSCA. In practice, these would be combined into a single check
which used NSCA as a primary method, falling back to NRPE if a check was late— for details see the
Nagios documentation (http://www.nagios.org/docs/) on Service and Host Freshness Checks.
