Yes, I understand the issue here. The code here <a href="http://www.louisville.edu/~tjande01/nagios/exthandler.c">http://www.louisville.edu/~tjande01/nagios/exthandler.c</a> uses a schedule_new_event callback that executes once a second in order to handle the socket code. Personally, I'd prefer to spawn a new thread to handle the socket communication with the check-command. This ties into the last thing that got missed off my original email that is: * Submit passive service check results The old school method of doing this is via the external command file, but I presume the new API has a method of doing this? There's some functions in broker.h that look like likely candidates, but they don't even have basic comments ;) (e.g. broker_service_check). The check-command that reports back to the broker module would only return state based on its ability to reach the switch and to talk to the broker module.
