Completing the installation

After installation, the HPjmeter console is available as a standalone tool or through Java Web Start from a server of your choice, such as the HP Systems Insight Manager central management server.

To complete installation, you need to configure the HPjmeter JVM agent by modifying the command line for each application for which you want to monitor or collect data. Then you need to start the HPjmeter node agent. The following sections will help you complete the installation.

•Platform Support and System Requirements (page 14)•File Locations (page 15)•Configuring your Application to Use HPjmeter Command Line Options (page 15)•Working with Firewalls (page 21)•For additional information on agents: Managing Node Agents (page 37)

File Locations

The default installation paths by operating system are as follow:•On HP-UX and Linux: /opt/hpjmeter•On Microsoft® Windows: C:\Program Files\HPjmeter

Attaching to the JVM Agent of a Running Application

For applications running with Java 6.0.03 or later, HPjmeter 4.2.00.00 can automatically identify the JVMs running on the server and display them symbolically in the console for attachment and monitoring. This includes JVMs for which no HPjmeter switches were used in the java command that started the applications. With few exceptions (discussed elsewhere in this guide), HPjmeter monitoring functionality is the same whether the JVM agent is loaded from the console (through dynamic attachment) or from the command line when starting the application.

Configuring your Application to Use HPjmeter Command Line Options

For most supported versions of Java, it is still necessary to start the application using HPjmeter options on the java command and to modify two environment variables. Or, you may want to use command line options to control the bytecode instrumentation.

Preparing to run Java

For most installations, linkage to the appropriate libraries is completed automatically as part of the installation process. Go to step 2 if you have a standard installation of the Java Runtime Environment.
