Introduction

The IBM® Monitoring and Diagnostic Tools for Java™ - Health Center is a diagnostic tool for monitoring the status of a running Java Virtual Machine (JVM). The Heath Center uses a small amount of processor time and memory, and can open some log and trace files for analysis.

The tool is provided in two parts:
The Health Center can be used to monitor Java applications, where the applications use one of the following JVMs:

The Health Center is provided as an IBM Support Assistant (ISA) add-on. For information about installing and getting started with the add-on, see: http://www.ibm.com/developerworks/java/jdk/tools/healthcenter/.

When the Health Center client starts up, you initially see a connection wizard. You can then:

The Health Center client is split into subsystems, each representing a component of the JVM. The following subsystems are available:

Subsystems are represented as Eclipse perspectives. The first subsystem you see is the Status perspective, listing the subsystems and their overall status. When you connect to a running application or open a file (see Opening files from disk for more information), subsystems with data available become links and any recommendations are displayed. The Health Center updates the displayed data and recommendations every 10 seconds. Switch to the subsystem perspectives using the links or the toolbar icons. You can return to the Status perspective using the furthest left toolbar icon.

You can send bug reports, feature requests, and feedback through your IBM representative, or you can post feedback or ask questions on the Health Center forum: http://www.ibm.com/developerworks/forums/forum.jspa?forumID=1461.
