Refer to the sample Nagios configuration section below for some examples of configuring
specific NSCA checks.
10.3.4 Configure Selected Serial Ports for Nagios Monitoring
The individual Serial Ports connected to the
console server
to be monitored must be configured for
Nagios checks. Refer to
Chapter 4.4—Network Host Configuration
for details on enabling Nagios
monitoring for Hosts that are network connected to the
console server
. To enable Nagios to monitor a
device connected to the
console server
serial port:
Select
Serial & Network: Serial Port
and click
Edit
on the serial Port # you want to monitor.
Select
Enable Nagios,
specify the name of the device on the upstream server and determine the
check you want to run on this port.
Serial Status
monitors the handshaking lines on the serial
port and
Check Port
monitors the data logged for the serial port.
10.3.5 Configure Selected Network Hosts for Nagios Monitoring
The individual Network Hosts connected to the
console server
that you want to monitor must also be
configured for Nagios checks:
Select
Serial & Network: Network Port
and click
Edit
on the Network Host you want to monitor.
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 want to monitor, without allowing
external (SDT Connector) access.
Select
Check TCP
to monitor.
The
Nagios Check
nominated as the
check-host-alive
check is the check 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.
