Threads Tree

The Threads Tree view serves many purposes. Typical use cases include the following:

  • View what kind of threads are being spawned by your application.

  • Monitor all threads and their activities.

  • Analyze each thread's activity.

  • Find and examine critical execution paths.

To open the Threads Tree view

  • Click on the corresponding icon ThemedIcon ModeStraightViewPerThread Screen png on the left panel.

The Threads Tree view lists all threads in your application. They are sorted by their execution time. Each thread is identified by its name or ID. The main thread is marked with the Main Thread png icon. The finalizer thread is marked with the ThemedIcon JetBrainsProfilerUIResourcesMeasureControllerStopDrop Screen png icon. Other threads are worker threads. If a thread pumps messages, it has the Thread with Message png icon, otherwise not.
