JConsole

JConsole is a graphical monitoring tool that comes with the Java Development Kit (JDK). It allows developers and system administrators to monitor and manage Java applications and Java Virtual Machines (JVMs) both locally and remotely. With JConsole, users can track various performance metrics, such as memory usage, thread activity, and CPU load, providing insights into application behavior. The tool supports JMX (Java Management Extensions) for connecting to applications, making it easier to diagnose issues and optimize performance. JConsole is particularly useful for real-time monitoring and can help in identifying bottlenecks in Java applications.
