Continuous Monitoring with JDK Flight Recorder

JDK Flight Recorder exposes ~150 JVM and application events, lets code create events by extending jdk.jfr.Event and calling begin/end/commit, and writes into thread-local buffers so production overhead stays <1% overhead by default. Recordings are started with -XX:StartFlightRecording or jcmd, inspected with jfr and Mission Control, and a small agent demo shows continuous consumption. Work on JFR Event Streaming / JMX-based remote streaming is underway so you can stream and act on events instead of postmortem analysis.
