# Introduction

The BEA JRockit Management Console is a JMX-compliant monitoring tool. It uses the extensive JMX instrumentation of the Java virtual machine to provide information on performance and resource consumption of applications running on BEA JRockit. This document contains procedures and information on how to monitor your running applications.

The following subjects are covered in this chapter:

- What is New in the BEA JRockit Management Console
- Console Overhead
- About this User Guide
- Finding Additional Information

# What is New in the BEA JRockit Management Console

- This version of the BEA JRockit Management Console has full support of Java MBeans (JMX).
- Look and feel has been updated to create a better user experience.

# Console Overhead

The extra cost of running the Management Console against a running BEA JRockit JVM is small and can almost be disregarded. This provides for a low cost monitoring and profiling of your application.

Note: We do not recommend that you run the Management Console on the same machine as the VM you are monitoring. If you run the Management Console on the same machine as the BEA JRockit you are monitoring, the Management Console GUI will steal valuable resources from the applications running on the JVM and you risk performance degradation as a result.

# About this User Guide

This document shows you what information you can get from your Java Virtual Machine (JVM), how to get that information, and how to interpret it. This user guide assumes that you know what a JVM is.

# Finding Additional Information

You can find additional information about BEA JRockit throughout the BEA JRockit documentation set. For a complete list of available documents, please refer to the BEA JRockit JDK Online Documentation.
