HPjmeter 4.3 User's Guide

3 Getting Started
Are You Monitoring an Application or Analyzing Collected Data?
HPjmeter helps you to monitor a live run of your application. You can also view saved data captured
using HPjmeter during a live session, by using profiling or garbage collection options when you
start your application, or if you are running HP JDK/JRE 5.0.04 (or higher), by starting and stopping
profiling data collection from the command line.
Choose the get started information appropriate for your activity:
• Using HPjmeter to Monitor Applications (page 34)
• Using HPjmeter to Analyze Profiling Data (page 39)

• Profiling with Zero Preparation (page 74)
Need a jumpstart?:
To aid in starting your use of HPjmeter, the console can display a beginning console guide
containing hints for getting started. The guide provides hints according to data set selected in the
console main pane.
To enable or disable the console guide, click Edit→ Window Preferences and toggle to the desired
option.
