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).
