rack-doge

Add this gem to a Rails app to get a log line like this for each request:

at=info thread_id=70351652783840 process_id=55394 request_id=013f9cc29c1e4c483435dbc15ab260f4 pre_request=0ms rack_in=202ms app=505ms rack_out=301ms

That includes:

• thread_id: For tracking requests across threads, (e.g. Puma)
• process_id: For tracking requests across workers (e.g. Puma or Unicorn)
• request_id: Correlate with you app (or Heroku router) logs
• pre_request: Measure the time between HTTP_X_REQUEST_START and the start of your rack stack (similar to New Relic's 'reuqest queueing' metric)
• rack_in: The time in the rack stack before your app sees the request
• app: The time spent processing the request in your app
• rack_out: The time spent going back out of the rack stack

Installation

Add this line to your application's Gemfile:

gem 'rack-doge'

And then execute:

$ bundle
