Plug in to RPM Developer Mode

or, for those who prefer to copy/paste:
script/plugin install http://svn.newrelic.com/rpm/agent/newrelic_rpm
Nice work! The New Relic agent is now installed.
Getting Started
- Whenever you run your app in development, the New Relic Agent tracks the performance of every http request. It stores the last 100 http transactions in memory.
- RPM presents this info as a collection of web pages within your application. To view performance information, including detailed SQL statement analysis, go to http://localhost:3000/newrelic and start drilling down.
- Try it as long as you like on your desktop. There's no expiration date.
- If you need help, check our Troubleshooting Guide & Documentation or reach out in the New Relic Forums.
- When you're ready to take your app to production, don't forget to take RPM with you.
