    you may want to try ACID (
    http://www.andrew.cmu.edu/~rdanyliw/snort/snortacid.html )
    
    it logs snort alerts into a database and can be used for data mining and
    graphing purposes (for the management-types out there). i sucessfully
    deployed an ACID machine a few months ago and have been very pleased
    with the results.
