I am new to Eventmachine/Goliath. I am now working on a API project using Grape + Goliath.
Everything else is fine except I am not sure how to do with the logging part.
I saw there's a `rack.logger` inside `env` and also saw the `custom_logs` example and the lantency example in Goliath wiki.
I am not sure what to do.
Is there a recommendation way for logging in Goliath, which will not block normal requests? I am using activesupport in my project so logger from activesupport is available if necessory.
Thank you very much!
