Finally, you need to add a User for the client running SDT Connector:

Select Users & Groups from the Serial & Network menu.

Click Add User.

In Username, enter: sdtnagiosuser, then enter and confirm a Password.

In Accessible Hosts click the IP address/DNS name of the IIS server, and in Accessible Ports click the serial port that has the router console port attached.

Click Apply.

10.3 Configuring Nagios Distributed Monitoring

To activate the console server Nagios distributed monitoring:

Nagios integration must be enabled and a path established to the central/upstream Nagios server.

If the console server is to periodically report on Nagios monitored services, then the NSCA client embedded in the console server must be configured—the NSCA program enables scheduled check-ins with the remote Nagios server and is used to send passive check results across the network to the remote server.

If the Nagios server is to actively request status updates from the console server, then the NRPE server embedded in the console server must be configured— the NRPE server is the Nagios daemon for executing plug-ins on remote hosts.

Each of the Serial Ports and each of the Hosts connected to the console server that you want to monitor must have Nagios enabled and any specific Nagios checks configured.

Configure the central/upstream Nagios monitoring host.

10.3.1 Enable Nagios on the Console Server

Select System: Nagios on the console server Management Console and tick the Nagios service Enabled.

Enter the Nagios Host Name that the Console server will be referred to in the Nagios central server—this will be generated from local System Name (entered in System: Administration) if unspecified.

In Nagios Host Address enter the IP address or DNS name that the upstream Nagios server will use to reach the console server— if unspecified this will default to the first network port’s IP (Network (1) as entered in System: IP).

In Nagios Server Address enter the IP address or DNS name that the console server will use to reach the upstream Nagios monitoring server.

Check the Disable SDT Nagios Extensions option if you want to disable the SDT Connector integration with your Nagios server at the head end— this would only be checked if you want to run a vanilla Nagios monitoring.

If not, enter the IP address or DNS name that the SDT Nagios clients will use to reach the console server in SDT Gateway Address.

When NRPE and NSCA are both enabled, NSCA is preferred method for communicating with the upstream Nagios server— check Prefer NRPE to use NRPE whenever possible (that is, for all communication except for alerts).
