Brief introduction of plug-ins for Nagios
Nagios itself does not contain any monitoring mechanism, and all its monitoring work is realized through plugin. These plug-ins are usually Perl or Shell scripts (usually in the / usr/local/nagios/libexec directory) that monitor the working status of the host or service through a command line, which is called by Nagios on demand and returns the execution result to Nagios. It is based on these return values that Nagios determines whether to "take some kind of action" (such as running an event handle (event handlers), sending notifications, and so on). The following figure shows the relationship between the plug-in relative to the Nagios process and the monitored object.
Official plug-ins are available to monitor the basic resources of the system, such as CPU load, disk utilization, Ping rate, etc. If you need to monitor the status of other forms of resources (such as CPU voltage, CPU fan speed, network traffic, etc.), you can use other official plug-ins or third-party plug-ins, of course, you can write your own plug-ins.
Official plug-ins usually provide simple help, which can be obtained by using "- h" or "--help" after each script. To get help for the plug-in script check_nt, you can use the following command:
