HPjmeter 4.3 User's Guide

Table 2 Console Requirements
The console is a pure Java application, so it should execute on any platform that
supports Java.
Operating system and
architecture
Java 6.x or 7.x versions.Java
HPjconfig can help you determine which Java patches are recommended or required
for best operation of the HPjmeter console on HP-UX. See

.
Processor and memory
• Minimum 500 MHz processor is recommended.
• Minimum 512 MB of memory on Microsoft Windows and 1 GB of memory on
UNIX systems is required.

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 24)
• File Locations (page 25)
• Configuring your Application to Use HPjmeter Command Line Options (page 25)
• Working with Firewalls (page 32)
• For additional information on agents: Managing Node Agents (page 47)
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 4.3.00.00 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.
