Our logs aren't just error messages; they're all sorts of messages that the user of our (backup) software may be interested in. I'm trying to figure out ways to reduce our messages so that our customers only see the details that they will really be interested in, but there is a large subset of our customers who want to be able to review how their backups went (and not just with the email summary that we send, which is generated from the log messages, BTW). Our tracing facility, on the other hand, is purely English.
