Java Flight Recorder (JFR) is one of the hidden gems of the Java platform - a mature, lightweight, production-grade profiling and telemetry subsystem. However, many developers don't know just how flexible and powerful this subsystem really is.

In this talk, Ben Evans will quickly introduce the basics of JFR and then explore some of the less well-known aspects and capabilities of JFR, including streaming, custom events, and integrating with open-source monitoring tools (including the new OpenTelemetry JVM Metrics standard).
