Rack::ProcessName

Set the process name to what request is currently being processed. If you're lucky and your OS shows process name changes, you'll see something like:

15696 ttys001    0:07.04 script/rails S GET http://localhost:3000/servers/localhost/edit   

The letter before the request method means:

  • R - running
  • S - sleeping (last response was ok)
  • E - error (last response raised an exception)

Installation

In Rails, just add to your Gemfile:

gem 'rack-process-name'

the gem will include itself as middleware.

If in Sinatra or using config.ru:

require 'rack-process-name'
use Rack::ProcessName
