A method for more effectively recording information in system logs is disclosed. In one embodiment, such a method includes detecting errors on a system such as a host system or storage system over a specified period of time. The method stores information associated with the errors in a memory buffer. The method further preprocesses the information in the memory buffer to condense the information and remove duplication. In certain embodiments, this preprocessing includes grouping errors by error type and providing a single stack trace or other information per error type. The method then outputs the preprocessed information to a log file. A corresponding system and computer program product are also disclosed.
