New Relic is introducing real-time Java profiling and a JVM cluster timeline view to help developers better understand performance bottlenecks in their Java applications and services. The feature uses data from the Java Flight Recorder (JFR) open-sourced by Oracle, allowing for low-overhead continuous profiling of Java code in production environments. The cluster timeline view provides a fast and intuitive way to diagnose cluster-wide performance problems, while the detailed view offers insights into code execution performance, resource allocation within processes, inefficient garbage collection, and connections with logs. These features are available in New Relic One, where developers can incorporate them with other critical observability data.
