Profiling and Monitoring with the JDK
summary
Java Flight Recorder (JFR) in the JDK records low-overhead JVM, application and OS events and lets applications emit and consume custom events via the Java 14 API. Since JFR became open source in Java 11 it can be used in production without a commercial license; the talk covers using JFR together with Java Mission Control (JMC) for profiling and monitoring to diagnose difficult performance and operational issues.
