Taking the pulse of your Rails app.
Track most popular actions and most requested actions. Get breakdowns of rendering time and database time on a per-action basis. Know your error code rates, HTTP request types, cache hit ratios, and more.
Rails analysis reports are generated through the excellent Request Log Analyzer.
All Scout needs is a path your application's log file. There is nothing to install in your Rails application, and you don't have to re-deploy to begin seeing great reports.
Easily monitor multiple Rails applications on one server.
Scout alerts you to any slow requests (within five minutes) so you can respond quickly to performance issues.
