The thread selection can be one of

• thread groups
• active threads
• dead threads

Next to the thread selector you find information about the thread state which is one of

• All states
  No filtering is performed.
• Runnable
  Only runnable thread states will be shown. This is the standard setting.
• Waiting
  Only waiting thread states will be shown.
• Blocked
  Only blocked thread states will be shown.
• Net I/O
  Only blocking network operations of the java library will be shown.

In the dynamic views thread selection and thread state are displayed in combo boxes. After changing the selection in the thread selector or the thread state selector, the dynamic views are updated immediately with the new settings. The thread selector applies to all dynamic views simultaneously. Initially it is set to All thread groups and may be switched to specific threads or thread groups as soon as they come into existence.

Please turn to the thread view section for more detailed information on threads.
