Active log session.   You can check a component in the list on the left and it will be added to the current log session.  You can uncheck a component and it will be removed from the current log session.   For any checked component you can check or uncheck the flags in the list on the right and it will immediately affect what is being logged for that component.   Same for changing the log level if the component supports levels.  Click the "Stop Logging" button to stop the log session.
