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
