Today marks the first release of the Production Log Analyzer.

The Production Analyzer lets you find out which pages on your site are dragging you down. pl_analyze requires the use of SyslogLogger (included) because the default Logger doesn't give any way to associate lines logged to a request.

http://rails-analyzer.rubyforge.org has installation instructions and the Production Log Analyzer can be downloaded from http://rubyforge.org/frs/?group_id=586
