New Relic RPM Now Manages Ruby Web Applications Running with Sinatra, Rack, and Rails Metal

Leading performance tool lets Ruby and Java developers monitor and optimize web applications that utilize latest technologies

San Francisco - February 24, 2010

New Relic, Inc., the leading software-as-a-service provider of application performance management solutions, today announced that the latest release of its RPM application performance management tool has added support for Sinatra, Rack, and Rails Metal, enabling Ruby developers and operations teams to monitor, troubleshoot, and optimize web applications that utilize these technologies. This support is one of several advanced capabilities for Ruby web application management available now.

"Rack has given Ruby web developers a tremendous amount of freedom to innovate and experiment with new ways of building web applications," said Ryan Tomayko, a member of the core committer team for both Rack and Sinatra. "Developers are increasingly turning to Rack and lightweight frameworks like Sinatra for small utility apps or for latching performance critical features onto an existing site. The ability to monitor and profile these applications using New Relic RPM fills a huge visibility gap for us."

Written in Ruby, Sinatra is an open source web application framework and domain-specific language (DSL) that enables rapid development of Ruby web applications. Rack is modular interface for developing Ruby web applications that simplifies the interaction between HTTP requests and other web application software components by distilling APIs for these systems into a single method call. Rails Metals are minimal Rack applications that enable requests to be served more quickly.

New Relic RPM is an on-demand performance management solution for web applications developed in Java, Ruby, or JRuby. RPM now provides real-time monitoring and metrics for applications running Sinatra, Rack and Rails Metals so development and deployment teams can quickly and cost-effectively monitor, troubleshoot, and tune Ruby web application performance to meet business goals.

"In the newest version of RPM’s Ruby agent we’ve added a number of significant features and support for Sinatra, Rack and Metals rank high among them," said Jim Gochee, New Relic’s vice-president of engineering. "One of the great things about developing a SaaS monitoring tool and being involved with the Ruby community is witnessing the constant innovation as more and more teams deploy business-critical Ruby web applications. Sinatra and Rack are two important examples of ongoing efforts to simplify the creation of traditionally complex web applications and we look forward to working with our customers and partners as they take advantage of these projects."

Comprehensive Web Application Management

Additional features of the New Relic RPM Ruby agent 2.10 include:
