10.4.2 Basic Nagios plug-ins
Plug-ins are compiled executables or scripts that can be scheduled to 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 that 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 preconfigured with two checks that are specific to Black Box:
