I'm probably a bit late on this, but: Please consider removing the need for a user to know about the "domain suffixes" (which, as far as I know are 24x7 specific). If anyone else ever wants to add firmware/hardware/kernel provided event descriptions, they'll need to special case these ones as they don't match up with the actual event names.
