Server User Manual

 Select System: Nagios and check NSCA Enabled.
 Select the Encryption to be used from the drop down menu, then enter a Secret password and
specify a check Interval.
 Refer to the sample Nagios configuration section below for some examples of configuring
specific NSCA checks.
10.3.4 Configure Selected Serial Ports for Nagios Monitoring
The individual Serial Ports connected to the console server to be monitored must be configured for
Nagios checks. Refer to Chapter 4.4—Network Host Configuration for details on enabling Nagios
monitoring for Hosts that are network connected to the console server. To enable Nagios to monitor a
device connected to the console server serial port:
 Select Serial & Network: Serial Port and click Edit on the serial Port # you want to monitor.
 Select Enable Nagios, specify the name of the device on the upstream server and determine the
check you want to run on this port. Serial Status monitors the handshaking lines on the serial
port and Check Port monitors the data logged for the serial port.
10.3.5 Configure Selected Network Hosts for Nagios Monitoring
The individual Network Hosts connected to the console server that you want to monitor must also be
configured for Nagios checks:
 Select Serial & Network: Network Port and click Edit on the Network Host you want to monitor.
 Select Enable Nagios, specify the name of the device as it will appear on the upstream Nagios
server.
 Click New Check to add a specific check which will be run on this host.
 Select Check Permitted TCP/UDP to monitor a service that you have previously added as a
Permitted Service.
 Select Check TCP/UDP to specify a service port that you want to monitor, without allowing
external (SDT Connector) access.
 Select Check TCP to monitor.
 The Nagios Check nominated as the check-host-alive check is the check used to determine
whether the network host itself is up or down.
 Typically this will be Check Ping—although in some cases the host will be configured not to
respond to pings.
 If no check-host-alive check 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.
