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.
