Hi Mathieu. A couple of questions at this point: 1) would the loglevel be inserted into every event as an additional attribute? As what, an integer? 2) Would you leave the interpretation and allowable values for "loglevel" open ended? It seems like that could be used for different levels of verbosity (but perhaps that is what "debug" is, verbose? 3) would it be possible to filter/disallow tracing of events dynamically based on the log level? I have done this a few times in the past in various systems I have designed. cheers, Aaron Spear
