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.
