What's a good logging replacement for rails?

So, I've been looking into logging in my Rails app and I'm discovering, thanks to posts like this, that the default Rails logging format is terrible and the开发者_如何学JAVAre isn't an easy way to change it. Can anyone recommend a simple replacement for the default logger?

Bonus question: Is there a stated reason for why it's so hard to change the default format in BufferedLogger?
