I'm sorry to say I do not. I've only very recently got a stable monitoring configuration in place with this as a key piece, parsing up messages and sending them to downstream programs.
I welcome the move away from regular expressions though - they are just not necessary in this particular domain. We'll see if PatternDB's coarse grained approach comes back to bite me.
I'm happy to help as I can if you decide to use PatternDB - you can find me at l.skibinski at elifesciences dot org. I have some notes for getting started quickly I really should publish ...
Very fast and a bit complex to setup, but well documented and well tooled. Mature. It could do with some more community love, tbh.
