Call for Log Samples

My log normalization effort made good progress and I have a very rough first proof of concept available. It will take a log sample database, and transform input log files to a CEE-like output format.
Now I am looking at ways to practice-test it. So I’d appreciate if you could point me to some sources of log files. It mustn’t be terabytes, but they should be anonymized and be usable in the public Internet. For obvious reasons, it would be good if they are from widely deployed devices.
I would use a subset of these samples to extract usable sample database entries and see how the run through the normalizer.
