Any Way to Dump Event Log in Crusader Kings 2?

I've found out how to open the console, but when I input debug_dumpevents, it tells me, in red text, that the command is only for developers.

So how can I access the list of events, such as you see scrolling along in the events window in the bottom of the page? I would like to keep record of the historical progression, and I would assume this data is being saved somewhere.
