Home > Profiling Tasks > Custom Profiling
Editing and Creating Custom Profiling Configurations
The Custom Profiling box appears when you choose to edit or create a configuration through the
Run Custom Profiling task.
This box allows you to further refine the profiling parameters for the different modes.
These modes are the same general profiling modes that are available as predefined commands.
The paramaters available depend on which of the following profiling modes you choose.
When working with a custom configuration, you can click Override Global Settings to override the
settings defined in Profiler Options dialog
. This will modify the settings for the configuration.
CPU Profiling
The basic choice between profiling the entire application, part of the
application, or the code fragment is the same as in the Analyze Performance command,
with the addition of the following profiling options:
- Method: full or sampled
- Timers: absolute, thread CPU or both
- Maximum number of profiled threads
- Instrumentation: filter
- Instrumentation: scheme
- Instrument/not instrument various special Java methods
For more about these settings, see CPU Profiling settings.
Memory Profiling
The basic choice between recording only object creation and the entire
object lifecycle is the same as in the Analyze Memory Usage command.
Additionally, the following options are available:
- Stack sampling depth: full or limited
- Take stack sampling every... (stack sampling interval)
- Run garbage collection when getting memory results
For more about these settings, see Custom Memory Profiling settings.
Monitoring
Monitoring mode has no options and works exactly the same way as the Monitor Application command.
Optional settings
Independent of the mode selected, the following options allow you to further control the profiling process and the results:
- Enable Thread Monitoring
When selected, system and application threads activity is monitored from application startup.
For more about these settings, see Thread Monitoring.
- Override Global Settings
For each configuration, you can modify the Profiler Options in the Global Settings
for Configuration dialog box. The dialog box enables you to modify the following settings:
- Working Directory
Specify the directory that will become current for your application when it starts. For
example, you may need to specify a specific working directory when attaching Profiler to a running JVM.
- Java Platform
The Java Platform combo box enables you to specify the target JVM to use when
profiling your application. The default JVM is the JVM the IDE is running on. The combo box
lists the available Java platforms. To add or remove a platform, choose Tools > Java Platform Manager
from the main menu.
- JVM Arguments
Specify any arguments to pass on to the JVM, for example, the default maximum heap size.
