The Health Center client and Health Center agent have unique platform requirements. The functionality available with the agent depends on the level of Java™ Runtime Environment (JRE) you are using.
The Health Center client requires either the Microsoft® Windows® or Linux® x86 operating system using the supplied JRE. The client is Eclipse RCP-based; the minimum operating system requirements for the client are the same as the Eclipse RCP project, see http://www.eclipse.org/documentation/.
The application that you want to monitor requires a minimum level of JRE with a Health Center agent installed. Later levels of JRE provide more Health Center function; the table shows at which JRE service refresh each function becomes available.
Some JRE levels come with an agent installed by default. To enable more function, install a later, updated, agent. See Installing the Health Center agent for more information. The level of function provided by default and updated agents is described in the following table.
To use Health Center on a production system, run Java 5 JRE SR10 or later, or run Java 6 JRE SR5 or later.
The Health Center has a minimal affect on the system being monitored. However, it is not suitable for production use on Java 5 JRE before SR10, or Java 6 JRE before SR5.
