Console Server & Router User Manual 217
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 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, 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
