Log only specific events from event bus

I am fiddling with actionable HTML5 notifications and while setting that up, I’d like to log all events on the event bus related to these HTML5 notifications with the default logger component. However, so far I seem to be able to just get it all (loglevel debug; will include sun.sun and a whole bunch of other events) or nothing at all (loglevel: warn).

Who knows how to set up the logger component to just show me the HTML5 Notify related events in the logs, and no other events?
