I've done various different log formats over the years including JSON. One thing I've done for logging errors or warning is to log them in RSS format. I monitor them just like any RSS feed. It's really handy because there's already tons of ways to read these logs so we don't have to create anything. I wouldn't use this for a debug log because it would probably be unusable if there was a large volume of logs, but for watching errors it's great.
