Logs, the huge chunks of meaningful data which looks like garbage to a normal eye. Well, analyzing logs have been an art. There are so many relevant and irrelevant stuff in it. Sometimes, it really shows what your Cognos environment is going through (provided you've set correct level of logging).
Partner labs in IBM Canada were working on an amazing tool to help customers out on analyzing their logs better. I'm pleased to see that they have released it for general public.

BTW, it's called IBM Cognos Exploration Tool for Event Analysis or ICETEA for short.
