This book is divided into three parts. The first section is a history of managing computer applications and an explanation of why JMX is needed for Java applications. The second part goes into detail about JMX and the third section is about JMX applications.

The first section is an informative history of managing computer applications from mainframes to present day applications. I the reader can skip this section, if he or she just wants to understand JMX.

The second section explains Means and the tools behind JMX-based management. MBeans represent a resource that a management system will monitor and control. The MBean is the resource according to the management server. The book goes into great detail in creating and using MBeans, including the MBean notification events. In this part, as throughout the book, the explanations are clear and comprehensive. The examples fully show the user how it works and are explained completely by the authors.

This book has a serious and comprehensive style. The authors assume that the reader has a fairly extensive knowledge of Java. This book is an excellent introduction to JMX and is comprehensive in its coverage of all topics related to JMX. I would recommend this book for anyone interested in learning about JMX.
