Thanks for your response.
Just one question to verify.
In the default configuration, all events of level info, debug and trace will be dropped, if
the ringbuffer is full. For all other events the application will block and if the ringbuffer
has space again, the block will release and the events will be written, right?
That means that only events of type Info, debug and trace could be lost, but none of the higher
levels like error, warn and severe, right?

Kind regards,
