Profiling Tasks
The Select Profiling Task dialog box is the main interface for selecting and running profiles.
Choosing a profiling command
The dialog box gives you five different ways of profiling the target application. The first four
items correspond to predefined profiling commands. The last command,
Run Custom Profiling, allows you to create your own custom profiling configuration.
You can choose from the following profiling commands:
- Monitor Application
This profile command returns
high-level information about several important properties of the target JVM, including thread
activity and memory usage.
- Analyze Performance
This profile command
returns detailed data on application performance. You can choose to analyze the entire
application, part of the application, or startup performance.
- Analyze Code Fragment Performance
This profile
command returns data on the performance of the code fragment you specify.
- Analyze Memory Usage
This profile command returns
data on object allocation and garbage collection.
- Run Custom Profiling
This command
is for running custom profiling configurations.
You can create, edit and save these custom configurations, allowing
you to control all the internal profile settings.
When you click on a profiling command the box expands, displaying a brief explanation of the command
and, for some tasks, allowing you to set some profiling options. Clicking Run at the bottom of the
dialog box launches the target application and starts the selected profiling command.
Only one task, i.e. one kind of profiling, can be active for
the profiled application at the given time (note, however, that monitoring is
always active, even when another task is chosen, since its overhead is very low).
