I'm pleased to announce that the latest version of the newrelic_rpm gem (3.8.0) takes advantage of these recent introspection improvements to give our Ruby customers some neat insights into how the Ruby VM is working for their applications. To demonstrate how these measurements can be useful, I'd like to show you how we used them …
