NCPA - passive mode
Posted: Thu Oct 18, 2018 8:05 am
Is communication from the server being monitored with NCAP to the Nagios host two way?
Thanks!
Thanks!
Passive checks are asynchronous communication and it's up to the external application, NCPA, to process and send the check results back to the server.
Here's how passive checks work:
1. An external application checks the status of a host or service.
2. The external application will write the results to an external command file.
3. Nagios will periodically execute a check result reaper event and scan the results.
Let me know if you have any other questions.
