Chapter 10: Nagios Integration
10.3.5 Configure selected Network Hosts for Nagios monitoring
The individual Network Hosts connected to the Console Server that is to be monitored must also be configured for Nagios
checks:
• Select Serial & Network: Network Port and click Edit on the Network Host to be monitored
• 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 wish to monitor, but do not wish to allow external (SDT
Connector) access
• Select Check TCP to monitor
• The Nagios Check nominated as the check-host-alive check is 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
