I am happy with the information I get out of the logging system and the formatting of errors and tracebacks. We've recently come across two things that could be handled nicer however. 1) we use multiple logfiles. one for *all* messages, and another for *special* messages. It would be nice if the concept of multiple logfiles and the routing of messages to files was part of the system. 2) the above, coupled with the use of twisd and starting the logfiles was a little weird. Our main logfile is attached to the application like this application.setComponent(ILogObserver, FileLogObserver(logfile).emit) and the other logfile just starts on its own. I had expected to attach both of them to the application and set up an event filter for each. It's a little non-symmetric the way it is. -T
