A.1 JMX Agent Implementations Section A.2 JMX Managers Section A.3 JMX-Enabled Products Notes Index JDMK provides a remote-manager component that includes a proxy for the MBeanServer, and proxies for the MBeans, to make the development of JMX managers easier It also provides a JMX manager and tools to help define and manage the MBeans For more information, see http://www.sun.com/software/java-dynamic A.1.3 TMX4J 1.0 from Tivoli Systems TMX4J 1.0[4] was released in February 2001 It is a cleanroom implementation of the JMX specification, and it is JMX compatible, not compliant It is available from IBM's alphaWorks Web site at http://alphaworks.ibm.comtech/TMX4J The licensing on this software is the standard alphaWorks trial license However, alphaWorks is now making technologies available for release by products on a pertechnology basis More information is available at http://www.alphaworks.ibm.com/license TMX4J contains an HTTP and RMI adapter, and support for a logging facility with JLog.[5] It also comes with a very nice tutorial IBM's products that support JMX use TMX4J, including WebSphere 5.0,[6] WebSphere Voice Server,[7] WebSphere Edge Server,[8] WebSphere Business Integrator,[9] WebSphere Business Components Composer,[10] and Tivoli Web Component Manager.[11] A.1.4 AdventNet Agent Toolkit Java/JMX Edition[12] AdventNet[13] was the first vendor to ship a product with JMX support Its management agent toolkit supported the JMX 0.8 version before the JMX specification was final The most recent version has passed the JMX TCK and is now fully JMX compliant You must purchase this product from AdventNet This toolkit includes a rapid prototyping and development tool for building JMX agents, and it includes adapters for SNMP, HTML, RMI, HTTP, CORBA, and TL1 (Transaction Language 1) It also supports distributed JMX agents in a gateway or cascading configuration, as well as the building of stand-alone SNMP and TL1 agents in Java You can get more information at http://www.adventnet.com/products/manageengine/index.html Other AdventNet products that use JMX are ManageEngine and Web NMS A.1.5 AdventNet ManageEngine AdventNet ManageEngine is a graphical development environment that helps developers expose business- or application-specific management information even after an application is developed and deployed JMS (Java Message Service) and Web service JMX adapters are also being supported to integrate the management infrastructure with the existing middleware infrastructure For more information, see http://www.adventnet.com/products/manageengine/index.html A.1.6 MX4J MX4J[14] is an open-source implementation release of the JMX 1.0 specification that is JMX compatible because it has not passed the JMX TCK This is understandable, given the current licensing arrangements for the TCK MX4J uses the Apache[15] licensing model It provides an HTTP, RMI-over-JRMP,[16] and RMI-over-IIOP adapter It also includes a tool that allows you to generate your MBean interface via XDoclet Another interesting extension of MX4J is dynamic proxy support for MBeans so that the calls to the MBeans in your programs are more intuitive The MX4J implementation has a logging facility that makes it fairly easy to redirect the data to another logging facility, such as log4j.[17] MX4J provides some additional service MBeans: a naming MBean that wraps the RMI registry, a mailer MBean that sends e-mail, and a JythonRunner MBean that runs Jython scripts You can find more information at http://mx4j.sourceforge.net A.2 JMX Managers A.2.1 Tivoli Web Component Manager Tivoli Web Component Manager provides performance and availability monitoring of Web applications, including Web servers, Web application servers, and JMX-enabled applications It also provides a framework to define and execute automated responses to problems When paired with Tivoli Web Services Manager[18] and

and service providers the ability to report on, create thresholds for, and take corrective actions on any exposed attribute to maintain performance and availability of JMX-enabled applications across multiplatform Web server environments You can find more information at http://www.dirig.com A.2.3 AdventNet Middleware Manager AdventNet Middleware Manager manages JMX-enabled applications deployed on J2EE servers like BEA WebLogic Server It adds JMX instrumentation for application-level information, in addition to using the JMX instrumentation available for the server infrastructure It provides a unified view of a network of servers, and it monitors the server and application components It reports on each segment of an end-to-end Web transaction so that performance and availability issues are quickly isolated You can find more information at http://www.adventnet.com/products/middleware A.2.4 AdventNet Web NMS AdventNet Web NMS provides an open, scalable, carrier-grade management infrastructure platform, with a suite of J2EE- and JMSbased cross-platform development framework, tools, modules, and APIs, as well as prepackaged applications Web NMS uses Java, CORBA, and other standards to deliver a management solution that communicates with managed systems (network elements, systems, and applications) It supports SNMP, TL1, XML, CORBA, and Telnet/CLI[20] protocols To
