Nsclient uses the nrpe method + windows to detect the UDP port bat script

Reference http://www.nsclient.org/nscp/wiki/NRPEListener

Uncomment the configuration item under [nrpe] In nsclient \ NSC. ini

Change [nrpe client handlers] to [nrpe handlers] and add the test script or command

You can use check_nrpe to add monitoring commands on the monitoring server. You can test the commands in the command line and then add them through centreon or manually.
