10. Nagios Integration • The Nagios Check assigned as the check-host-alive check determines whether the network host is up or down. • Typically, this will be Check Ping. In some cases, the host will be configured to not respond to pings. • If no check-host-alive is selected, the host will always be assumed to be up. • You may deselect check-host-alive by clicking Clear check-host-alive. • If required, customize the selected Nagios Checks to use custom arguments. • Click Apply. 10.2.6 Configure the Upstream Nagios Monitoring Host Refer to the Nagios documentation (found at http://www.nagios.org/docs/) for configuring the upstream server: • The section Distributed Monitoring provides step-by-step detail for configuring NSCA on the upstream server (under Central Server Configuration). • NRPE Documentation has recently added steps for configuring NRPE on the upstream server. For more information, visit http://nagios.sourceforge.net/docs/nrpe/NRPE.pdf. At this point, Nagios upstream monitoring server has been configured and individual serial port and network host connections on the console server have been 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. 189
