This can be done in one of two ways — first, with configuration.As shown below, we're setting the format specification to show the log message's datetime and message and the program's name.

In contrast, in the first example, the application concatenates the string before inspecting whether the log level applies.By default, we typically log into environment-specific log files in our Rails app.It will simplify debugging and help reduce log pollution when things are logged at too high a level.Some of you may have noticed we can log in different ways.When building an application, using a Rails logger or similar gem puts you on the path to proper application logging.

To handle logs in a running application, the Rails logger provides additional functionality.After setting the logging level, let's improve readability by setting a simple logging format.First, let's change the datetime format of the logging messages, continuing on from our configuration above.However, logging into a server in order to grep or tail a file lacks any real-world usability. With Retrace, you can consolidate and view logs easily. And, most interestingly, you can analyze trends in the logs.We need a way to mine our logs for information as well as stay on top of issues and metrics. Installing and configuring Retrace for your Rails app involves just a few steps.Before we move on to best practices, I want to make one additional note.
