undefined method `reset' for #<ActiveSupport::Logger

Hi,
Following the documentation, I put Rails.logger.reset into config/puma.rb

On server start though, I get an error:

undefined method reset' for #ActiveSupport::Logger:0x00007f932cfdb148 6: from /Users/marina/.rbenv/versions/2.5.3/lib/ruby/gems/2.5.0/gems/puma-3.12.0/lib/puma/cluster.rb:137:in fork' (NoMethodError ( 5: from /Users/marina/.rbenv/versions/2.5.3/lib/ruby/gems/2.5.0/gems/puma-3.12.0/lib/puma/cluster.rb:137:in block (2 levels) in spawn_workers'
NoMethodErrorNoMethodError)`

Thanks and sorry if I'm missing something obvious here. KR

After looking closer and going through merged PRs I found out that reset method was exposed and it is actually a feature, BUT:

If you run into this error, you still have Rails.logger not set to Logstash. If Logstash logging is conditional in your application, you better put Rails.logger.reset under a condition like if respond_to?(:reset) or if ENV['LOGSTASH_ENABLED'] like I did in my project.

I'd suggest to put this advice into a README.

Thanks!

In case of multilogger, the instance does not respond to reset method.

logger.loggers.each { |_logger|
 _logger.respond_to?(:reset)
}

This will work
