[JAVA][Beginning Java 8 Games Development]

Chapter 2 ■ Setting Up Your Java 8 IDE: An Introduction to NetBeans 8.0
After you run the NetBeans 8.0 Profiler, you will see that a Profiler tab has been added to your Projects, Files,
and Services tabs, at the left of the IDE, as illustrated in Figure 2-17. You examined these other three tabs earlier in
the chapter (see the section “NetBeans 8.0 Is Efficient: Organized Project Management Tools”), so let’s explore the
Profiler tab now.
Figure 2-17. Profile’s Basic Telemetry section, at the left of the IDE, under the Profile tab, shows methods, threads, and
total and used memory
At the top of the Profiler tab is the Controls section, with Stop (Terminate) Profiled Application, Reset Collected
Profiling Results Buffer, Garbage Collection, Modify Profiling Session, and VM Telemetry Overview icons.
Below these is the Status section, showing the type of profiling you have selected (in this case, CPU), the
configuration (Analyze Performance), and the Status (Running).
The Profiling Results section contains icons that open tabs in the code editor section regarding profiling data
results (reports), and the View section does the same thing for virtual memory (VM) telemetry, threads, and thread
lock contention. You will be looking at some of these in the next section, when you profile memory usage (you are
currently profiling CPU usage).
You can save snapshots of various points in time during your code profiling sessions in the Saved Snapshots
section. The Basic Telemetry section shows statistics regarding the profiling session, including number of methods,
filter settings, threads running, and memory usage.
