J. Steven Perry

Enterprise Java's management technology is called Java Management Extensions (JMX). JMX provides patterns, APIs, and architecture for managing any application resource, including queues and connection pools. The patterns are used to encapsulate your application resources as managed beans (MBeans) by defining the management interface for each resource. The APIs are then used to register the MBeans with the MBean server, which acts not only as a registry for MBeans, but also as a communications bus for management applications to obtain information about registered MBeans. The JMX architecture defines how MBeans, the MBean server, and management applications interact.

In this chapter we will take a look at some best practices for MBean naming and instrumentation. Each section presents a problem or issue, some possible approaches to addressing it, and the practice or pattern that best solves it.
