2.2 Java Mission Control

The Java Mission Control (JMC) is a new JDK profiling and diagnostics tools platform for HotSpot JVM. It is a tool suite for basic monitoring, managing, and production time profiling and diagnostics with high performance. Java Mission Control minimizes the performance overhead that's usually an issue with profiling tools. This tool is a commercial feature built into the JVM and available at runtime.

The Java Flight Recorder (JFR) is a commercial feature. You can use it for free on developer desktops/laptops, and for evaluation purposes in test, development, and production environments. However, to enable JFR on a production server, you require a commercial license. Using JMC UI for other purposes on the JDK does not require a commercial license.

The Java Mission Control (JMC) consists of Java Management Console (JMX), Java Flight Recorder (JFR), and several other plug-ins downloadable from the tool. The JMX is a tool for monitoring and managing Java applications and the JFR is a profiling tool. Java Mission Control is also available as a set of plug-ins for the Eclipse IDE.
