Java Flight Recorder is a profiling and event collection framework built into the Oracle JDK. It can be used to collect detailed, low-level information about the behavior of the Java Virtual Machine (JVM) and Java application. JDK Mission Control is an advanced set of tools that allows you to analyze the vast amount of data collected by Java Flight Recorder efficiently and in detail.

JMap is a utility that, when using jmap with a process file or kernel without any command line options, prints a list of loaded shared objects (the output is similar to the pmap utility in the Oracle Solaris operating system). For specific information, the -heap, -histo, or -permstat options can be used.

Jps is a utility useful in environments with an embedded virtual machine. Allows you to easily recognize Java processes in the process list.

JStack is a command-line utility that attaches to a specified process or kernel file and prints a stack trace of all threads that are attached to the virtual machine. The utility also detects deadlocks.

JStat is a utility that provides information about the performance and resource consumption of running applications.

The jstatd Daemon is an RMI application server that controls the creation and termination of each instrumented Java HotSpot and provides an interface that allows remote monitoring tools to connect to JVMs running on the local host.

Visualgc is a tool that provides a graphical representation of the garbage collection system. Uses built-in Java HotSpot virtual machine tools.

Pinpoint is an APM (Application Performance Management) tool for large scale distributed systems written in Java, PHP or Python. Pinpoint provides a solution that helps you analyze the overall structure of the system and how the components in them are interconnected by tracking transactions in distributed applications.
