Join Kevin Skoglund for an in-depth discussion in this video Logging to log files, part of Ruby on Rails 3 Essential Training.

In this movie, we'll take a look at the log files Rails uses.…Learn how to configure them and how to write your own information to them.…Note that the log files I'm referring to here are the Rails application logs,…which are very different from the log files that the web server uses.…Errors that occur before a request gets to your application and errors…regarding startup and communicating with your application will show up in the server logs.…But the web server only knows about the requests that come in and the data…that it sends back.…Everything that happens once it passes off that request to the application…remains a mystery to it, but the Rails log files can provide lots of detail…about what happens as Rails processes the request.…
The kind of information that gets logged can be configured and can be different…for each of your environments.…As we saw in the last movie, by default, development is set to the :debug log_level.…The production environment is going to be set, by default, to the :info log_level.…
