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.
