Log files provide important information for troubleshooting complex systems. However, the structure and contents of the log data and messages vary widely. For automated processing, it is necessary to first understand the layout and the structure of the data, which becomes very challenging when a massive amount of data and messages are reported by different system components in the same log file. Existing approaches apply supervised mining techniques and return frequent patterns only for single line messages.
