The Logging Service logs every event that takes place in the system that is set to be logged. On a Windows platform these logs are optionally written to the Event Log. Where such services exist on other platforms they are used as appropriate. Exceptions are automatically logged with their complete stack traces.

"set to be logged" seems to imply getting configuration data on what to log.
I suppose that it should be a choice, but I can't say that I am personally fond of dumping this sort of information into a generic OS log ... it should be someplace where it is more conspicuous.
This should also include an option for centralized logging. E.g., whenever an unhandled exception occurs, I want that to show up in a central location.
