I just wanted to give a heads up on the status of log normalization. We have just released updated versions of libee and liblognorm. These provide important new features, like the capability to annotate events based on classification. This, among others, brings the libraries more back inline with recent CEE developments. Also, the log normalizer tool is nearly ready for prime time. The "only" thing that is missing is a decent set of rule bases. Thankfully, sagan already has a couple. I guess besides programming obtaining rule bases is a major thing to target.
As soon as I find time (I hope soon!), I'll finalize some lose ends on the software side and get doc online on how to use the normalizer tool. I think with that a great tool for everyday use in log analysis will become available. Feedback and collaboration is always appreciated!
