You use this panel to configure settings that effect the behavior of the IDE when profiling applications.

You can access this panel by choosing Tools > Options from the main menu, clicking the Miscellaneous category and then clicking the Profiler tab.

You can specify the following Profiler settings:

### General

- Profiler Java Platform. Choose a Java platform from the drop-down list to specify the target JVM to use when profiling your application. The default JVM is the JVM the IDE is running on. The dropdown list lists the available Java platforms. To add or remove a platform, click Manage Platforms to open the Java Platform Manager.
- Communication Port. You can also change the communication port that the profiler listens to. The default port is 5140.

### When Profiling Session Starts

- Open Telemetry Overview. Specify when the Telemetry Overview window opens by choosing an option from the drop-down list.
- Open Threads View. Specify when the Threads window opens by choosing an option from the drop-down list. For example, if you want the Threads View to open every time you start a profiling session, select Always from the drop-down list.
- Open Live Results For. Select a profiling session type if you want the Live Results window to be automatically opened when the starting the selected type of profiling session.

### Miscellaneous

- When Taking Snapshot. Choose an option from the drop-down list to specify what the IDE does when you take a snapshot, either manually or using a profiling point. For example, if you select Save New Snapshot, when you click Take Snapshot the snapshot is saved and appears in the Snapshot list but does not open in the Profiling Results tab.
- On OutOfMemoryError. Choose an option from the drop-down list to specify what the IDE does when an OutOfMemoryError is encountered. The default behaviour is to save the heap dump to the profiled project.
- Heap Walker Settings. When selected, enables automatic rule-based analysis of heap dump structures.
- Profiler Dialogs Confirmations. Clicking Reset automatically resets the Do Not Show This Message Again checkbox in all dialog boxes to the default state of unselected. This means that if you want to stop a dialog window from appearing, you need to select the Do Not Show checkbox in that dialog window.
