Rack::AccessLog

This is a middleware for ruby / rack based webservice access logging. The implementation doesn't depend on any webframework or monkey patch.

Installation

Add this line to your application's Gemfile:

gem 'rack-access_log'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rack-access_log

Usage

First we need a logger that can accept and handle hash messages.

You can use the ruby build in with "custom" formatter.

require 'json'
require 'logger'

json_logger = Logger.new(STDOUT)
json_logger.formatter = proc do |severity, datetime, progname, msg|
  JSON.dump(msg) + "\n"
end

Or you can use logger implementations such as TwP/logging gem

require 'logging'

json_logger = Logging.logger["AccessLog"]
appender = Logging.appenders.stdout(:layout => Logging.layouts.json)
json_logger.add_appenders(appender)

Than use it in our middleware stack

config.ru

require 'rack/access_log'
use Rack::AccessLog, json_logger

require 'rack/response'
run proc{|env| Rack::Response.new.finish }

That's all Folks!
