A web application as a logging frontend for Ruby

I was looking for a web application that h开发者_如何学JAVAopefully catches log messages sent from Ruby programs and display them , much like the Chainsaw program (in integration with log4r). I tried to Google anything related but with no success so far. Does anybody have a suggestion ? Thanks in advance.

There is a list of web viewers for log4j logs here. Some of them are web-based.
