10.4.2 Basic Nagios plug-ins

Plug-ins are compiled executables or scripts that can be scheduled to be run on the Console Server to
check the status of a connected host or service. This status is then communicated to the upstream
Nagios server which uses the results to monitor the current status of the distributed network. Each
Console Server is preconfigured with a selection of the checks that are part of the Nagios plug-ins
package:

check_tcp

and

check_udp

are used to check open ports on network hosts

check_ping

is used to check network host availability

check_nrpe

is used to execute arbitrary plug-ins in other devices

Each Console Server is also preconfigured with two checks that are specific to the Console Server:

check_serial_signals

is used to monitor the handshaking lines on the serial ports

check_port_log

is used to monitor the data logged for a serial port.

10.4.3 Additional plug-ins

Additional Nagios plug-ins (listed below) are available for all the Tripp Lite Console Servers:
