Architecture of the JMX Technology by R4R Team

Architecture of the JMX Technology:-
 The JMX technology can be divided into three parts, as follows:
 1 Instrumentation
 2 JMX agent
 3 Remote management
 1 Instrumentation:
 Using the JMX technology, you must first instrument the resources in the Java programming language. You use Java objects known as MBeans to implement the access to the resources' instrumentation. MBeans must follow the design patterns and interfaces defined in the JMX specification. Doing so ensures that all MBeans provide managed resource instrumentation in a standardized way. In addition to standard MBeans, the JMX specification also defines a special type of MBean called an MXBean. An MXBean is an MBean that references only a pre-defined set of data types. Other types of MBean exist, but this trail will concentrate on standard MBeans and MXBeans.
 Once a resource has been instrumented by MBeans, it can be managed through a JMX agent. MBeans do not require knowledge of the JMX agent with which they will operate.
 2 JMX Agent:
 A JMX technology-based agent (JMX agent) is a standard management agent that directly controls resources and makes them available to remote management applications. JMX agents are usually located on the same machine as the resources they control, but this arrangement is not a requirement.
 The core component of a JMX agent is the MBean server, a managed object server in which MBeans are registered. A JMX agent also includes a set of services to manage MBeans, and at least one communications adaptor or connector to allow access by a management application.
 3 Remote Management:
 JMX technology instrumentation can be accessed in many different ways, either through existing management protocols such as the Simple Network Management Protocol (SNMP) or through proprietary protocols. The MBean server relies on protocol adaptors and connectors to make a JMX agent accessible from management applications outside the agent's Java Virtual Machine (Java VM).
 Each adaptor provides a view through a specific protocol of all MBeans that are registered in the MBean server. For example, an HTML adaptor could display an MBean in a browser.
