Ruby, celebrated for its simple syntax, powers the Ruby on Rails framework, and now benefits from Datadog's Continuous Profiler, which is generally available for Ruby applications. This tool provides low-overhead, code-level performance insights, allowing developers to view resource usage of individual Ruby methods, correlate profiles and distributed traces, and compare profiles across different dimensions. As Ruby applications grow, identifying bottlenecks becomes more challenging, but the Continuous Profiler automatically collects stack traces and visualizes them in flame graphs to highlight resource consumption. It integrates with Datadog APM for end-to-end distributed tracing, enabling developers to uncover potential bottlenecks by examining traces with errors or high latency. The profiler supports performance verification by comparing profiles from different versions, particularly useful for canary releases, and allows performance comparisons across environments using Datadog tags. Additionally, Continuous Profiler is available for Java, Python, and Go, with support for more languages in development, and Datadog offers a 14-day free trial for new users.
