Much of the information that jstat provides can be gleaned from visual tools such as VisualVM, JMX and platform MBeans, garbage collection logs, or via JVM options. Instrumentation for the HotSpot JVM was introduced with Java 1.4.1 (only enabled when -XX:+UsePerfData was set) and has provided "always-on instrumentation" since Java 1.4.2. The Oracle JDK 9 Documentation Early Access states that jstat is used "to monitor Java Virtual Machine (JVM) statistics." There is also a warning, "This command is experimental and unsupported." Although I quoted the JDK 9 documentation, jstat has been a part of the Sun/Oracle JDK in some form ( known at one time as jvmstat) in Java SE 8, Java SE 7, Java SE 6, and J2SE 5. I have written about several command-line tools provided with the Oracle and/or OpenJDK Java Development Kits (JDKs) in the past, but I've never written exclusively about the jstat tool.
