The changes would be tracked in a VCS and upgrades are unlikely, but an alternative (cleaner) approach would be interesting. I am brand new to C but have experience with several other languages, and have never heard of nagios before yesterday. Could you give me a more newb friendly suggestion to your approach?

I have only found one instance of cnf_dir in the source and that is here: else if(strstr(input,"cfg_file=")==input || strstr(input,"cfg_dir=")==input) continue; in config.c line 1328.

You could write an eventbroker module that loads the configuration by creating all the hosts and services you need though. You'll want the NEBCALLBACK_PROGRAM_STATUS events, and the NEBTYPE_PROCESS_START type. </pre> </blockquote> </body> </html>
