9.2
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, 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, 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 which are to be
monitored must have Nagios enabled and any specific Nagios checks configured
§
Lastly the central/upstream Nagios monitoring host must be configured
9.2.1 Enable Nagios on the console server
1.
Select
System > Nagios
on the console server Management Console and tick the Nagios service
Enabled
2.
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
3.
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
)
4.
In
Nagios Server Address
enter the IP address or DNS name that the console server will use to
reach the upstream Nagios monitoring server
