I'm using OtrosLogViewer http://code.google.com/p/otroslogviewer with batch processing https://code.google.com/p/otroslogviewer/wiki/BatchProcessing. Following method of your log processing logic is called when log event is parsed.
 logDataParsed(LogData data, BatchProcessingContext context);
Additionally you are notified when processing is started/finished.
