Passive_check service definition

I have snmptrapd writing events to Nagios’ external command file. However, I am at a loss as to how to get Nagios to check that file. Specifically, what do I need for a service definition to check the external command file? Is there a plugin I should have to do this? Any help would be appreciated!


Please don’t do that. Double post, that is.

I though I put too much information in the first one. Sorry for double posting.
