How does the RPM Developer Mode feature work?
• The New Relic RPM Rails plug-in installs with zero configuration. • 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. Don’t worry-these pages stay in development mode, for your eyes only! When your app is in development mode, the agent doesn’t report data to NewRelic.com or anywhere else. • 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. • When you’re ready to take your app to production, don’t forget to take RPM with you.
