JMX Monitoring

What is JMX?

Java Management Extensions (JMX) is a Java technology that enables dynamic management and monitoring of Java applications. It provides an API that allows developers to expose application metrics, which can then be accessed using monitoring tools.

JMX consists of three key components:

• MBeans (Managed Beans): Objects representing application components, such as memory usage, active threads, and database connections.
• JMX Agent: The core component that exposes MBeans and enables remote monitoring.
• Connectors & Adapters: Interfaces that facilitate communication between JMX clients and applications over protocols like RMI and HTTP.

What is JMX Monitoring?

JMX monitoring is the process of collecting, analyzing, and managing performance metrics from Java applications using the JMX framework. It provides a standardized way to track the health and efficiency of Java applications, ensuring optimal performance and reliability.
