How to add a custom log level to logger in ruby?

Question

I need to add a custom log level like \"verbose\" or \"traffic\" to ruby logger, how to do?

Answer 1

This is an old question, but since it comes up so high on google, I figured it'd be useful to have to correct answer. You can actually use the Logging.init method. Here's how you would add a trace log level

require 'logging'
Logging.init %w(trace debug info warn error fatal)
Logging.logger.root.level = :trace
Logging.logger.root.add_appenders Logging.appenders.stdout
Logging.logger['hello'].trace 'TEST'

This is using the 2.0.0 of the logging gem.
