Java's Observability and Monitoring Framework - JFR
JDK Flight Recorder (JFR) is Java’s Observability and Monitoring framework that’s built directly into the HotSpot JVM. JFR's low overhead and always-on capability allow it to provide a rich view of the JVM and applications running on it. In this episode of Stack Walker, we take a look at JFR’s history and review its architecture to see how it is able to achieve these remarkable performance goals.
