Abstract: An approach for managing log messages. In this approach, a hierarchical structure identifies primary and secondary relationships between the log messages. In this approach, primary log messages in the log messages that has one or more secondary log messages is identified using the hierarchical structure. One or more pointers are added to each primary log message in the log messages having the one or more secondary log messages. Each pointer points to a secondary log message in the hierarchical structure. The one or more secondary log messages are removed from the log messages to form remaining log messages. Header information from log message headers and content information from log message content in the remaining log messages are saved to form compressed log information.
