JConsole

JConsole is a monitoring tool that comes with the Java Development Kit (JDK) and provides a graphical interface for managing and monitoring Java applications. It allows users to connect to Java Virtual Machines (JVMs) and gather performance metrics, such as memory usage, thread activity, and CPU load. JConsole can also be used to monitor MBeans, which are Java objects that follow the Java Management Extensions (JMX) specification, enabling dynamic management of resources. This tool is particularly useful for developers and system administrators to diagnose performance issues and optimize application behavior in real-time.
