How to: Attach and Detach Performance Tools to Running Processes

The profiler can be used to attach to or detach from a running process to make sampling and gathering performance data easier. You can use this method to profile a process when you want to avoid gathering data about application load time, or to monitor the performance of a process after it reaches a specific state.

The processes that are available to profile depend on the User Access Permissions that are set by an administrator of the computer. A User account may, for example, have permission for any of the following:

• Advanced profiling features, when the administrator has set the driver and service to start.

• Sample profiling only (domain users).

• Deny access to profiling to everybody.

  For more information, see Profiling and Windows Vista Security and the ADMIN options in VSPerfCmd.
