How to integrate newrelic rpm with rails

Hello,
          If you want to measure the performance (loading time) of your application than use newrelic rpm plugin/gem.

Either install newrelic plugin or gem.

script/plugin install http://newrelic.rubyforge.org/svn/newrelic_rpm
or
gem install newrelic_rpm
Add config.gem "newrelic_rpm" in environment.rb

Now in config edit the newrelic.yml
If you want to monitor application in development mode than set monitor mode

development:
  <<: *default_settings
   monitor_mode: true
   developer_mode: true

Now access the http://localhost:#{port}/newrelic. it shows the time consumption as per request. so from this you will get idea from where most time consumed. Based on that you can optimize the code to save time.
