Using NSCA
Passive checks are sent to Nagios via the external command pipe. As it is a named pipe on a specific machine, the main problem is that all passive check results need to be sent from this machine.
Very often, checks need to be carried out on one or more remote hosts. This requires a mechanism to pass results from the machines that perform the tests to the computers running the Nagios daemon, which will process the results. This is why NSCA was developed.
