I started working on a rails log parser but there appears to be a very nice one on
ruby forge. Since they have a lot of nice things i will not even finish the code I have in the SVN. From the little work I did with the log parser I did find out that %13.91 of my logged server requests had stack traces, and that %51.23 of the logged session ids are uniq. So I will check out the ruby forge project and see how that goes.
