Remarks

The events are buffered in this appender until conditions are met to allow the appender to deliver the events to the attached appenders. See BufferingAppenderSkeleton for the conditions that cause the buffer to be sent.

The forwarding appender can be used to specify different thresholds and filters for the same appender at different locations within the hierarchy.
