To integrate third-party management systems with the WebLogic Server management system, WebLogic Server provides standards-based interfaces that are fully compliant with the Java Management Extensions (JMX) specification. Software vendors can use these interfaces to monitor WebLogic Server MBeans, to change the configuration of a WebLogic Server domain, and to monitor the distribution (activation) of those changes to all server instances in the domain. While JMX clients can perform all WebLogic Server management functions without using Oracle's proprietary classes, Oracle recommends that remote JMX clients use WebLogic Server protocols (such as T3) to connect to WebLogic Server instances.
This document describes creating JMX clients that monitor and modify WebLogic Server resources.
The following sections describe the contents and organization of this guide—Developing Custom Management Utilities with JMX.
This document is a resource for software vendors who develop JMX-compatible management systems. It also contains information that is useful for business analysts and system architects who are evaluating WebLogic Server® or considering the use of JMX for a particular application.
It is assumed that the reader is familiar with Java EE and general application management concepts. This document emphasizes a hands-on approach to developing a limited but useful set of JMX management services. For information on applying JMX to a broader set of management problems, refer to the JMX specification or other documents listed in Related Documentation.
This chapter, Chapter 1, "Introduction and Roadmap,", introduces the organization of this guide.
Chapter 2, "Understanding WebLogic Server MBeans," describes the JMX services that you use to monitor and manage WebLogic Server MBeans and introduces the data model that organizes WebLogic Server MBeans.
Chapter 3, "Overview of WebLogic Server Subsystem MBeans," introduces the MBeans that can be used to monitor and manage various subsystems of WebLogic Server.
Chapter 4, "Accessing WebLogic Server MBeans with JMX," provides instructions and examples for accessing WebLogic Server MBeans from a JMX client.
Chapter 5, "Managing a Domain's Configuration with JMX," provides instructions and examples for managing a WebLogic Server domain's configuration through JMX.
Chapter 6, "Managing Security Realms with JMX," describes the hierarchy of security MBeans, how to choose an MBean server to manage security realms, how to work with existing security providers, and how to modify realm configuration.
Chapter 7, "Using Notifications and Monitor MBeans," describes working with notifications and listeners to listen for changes in WebLogic Server MBean attributes.
Chapter 8, "Configuring WebLogic Server JMX Services," describes how to specify which JMX services are available in a domain.

Oracle Fusion Middleware Using Logging Services for Application Logging for Oracle WebLogic Server describes WebLogic support for internationalization and localization of log messages, and shows you how to use the templates and tools provided with WebLogic Server to create or edit message catalogs that are locale-specific.
Oracle Fusion Middleware Configuring and Using the Diagnostics Framework for Oracle WebLogic Server describes how system administrators can collect application monitoring data that has not been exposed through JMX, logging, or other management facilities.
For guidelines on developing and tuning WebLogic Server applications, see the following documents:
Oracle Fusion Middleware Developing Applications for Oracle WebLogic Server is a guide to developing WebLogic Server applications.
Oracle Fusion Middleware Developing Manageable Applications With JMX for Oracle WebLogic Server describes how to create and register custom MBeans.
This release of WLS adds the ability to register custom MBeans in the Domain Runtime MBean Server. See Make Local Connections to the Domain Runtime MBean Server, and "Registering Custom MBeans in the Domain Runtime Server" in Oracle Fusion Middleware Developing Manageable Applications With JMX for Oracle WebLogic Server for more information.
