Chapter 1. Java Management Extensions Concepts
The growth of large-scale distributed applications in the past decade has been impressive. Mission-critical business applications have evolved from a sequence of programs running on a single computer to business components running on different machines scattered throughout a network. Managing one application running on a single computer is fairly straightforward; you can monitor the health of the application through the use of a single log file, or operator console, and tools provided by the operating system. The difficulty of managing today’s distributed systems has increased along with the complexity of those systems. When considering a management solution for today’s enterprise applications, some questions arise:
Which management solution is best for the application?
What standards should a management solution follow?
How much effort is required to enable the components of the application to be managed?
Java Management Extensions ( JMX), the result of the Java Community Process ( JCP) Java Specification Request ( JSR) 3, was designed to deal with all of these questions. JMX was designed to address the management needs of applications written for the Java platform and to be compatible with existing management standards, such as the Simple Network Management Protocol (SNMP), which is the standard for management of enterprise networks. It was also designed so that instrumentation of resources to put them under the control of a management ...
