'''JDK Flight Recorder''' is an event recorder built into the [[Java virtual machine]]. It can be thought of as the software equivalent of a Data Flight Recorder (Black Box) in a commercial aircraft. It captures information about the [[Java virtual machine|JVM]] itself, and the application running in the JVM. There is a wide variety of data captured, for example method profiling, allocation profiling and garbage collection related events. The '''JDK Flight Recorder''' was designed to minimize the [[Observer effect (information technology)|Observer Effect]] in the profiled system, and is meant to be always on in production systems. The technology was open sourced in 2018.
