Intel® VTune™ Amplifier enables you to focus your performance analysis on a specific process.
Note
Attaching to .NET processes is not supported for hardware event-based sampling analysis types.
VTune Amplifier provides limited support for profiling Windows* services. For details, see Profiling Windows Services article on the web.
To specify a process as the analysis target:
- Click the
![]()
Project Properties button on the VTune Amplifier toolbar.The Project Properties dialog box opens with the Target tab enabled.
Project Properties button on the VTune Amplifier toolbar.To detach from the process, click the 
Stop button on the command toolbar. The process will keep running but the analysis will be stopped.
You can use the VTune Amplifier to profile the Windows kernel-mode process and analyze all privileged resource operations (for example, memory management, paging) it is responsible for or to explore your multithreaded kernel-mode drivers running in the context of this process. If you are a driver developer, this option can help you profile asynchronous driver threads and identify system resource utilization issues (for example, issues caused by frequent page allocations). To analyze the system process, run the VTune Amplifier with administrative privileges and configure the analysis target to attach to PID 4. In case of event-based call stack collection, call stacks will show kernel-mode functions only (because of the absence of the user-mode context).
Tip
To focus on analyzing particular processes, you may collect data on all processes (without selecting the Attach to Process target type) and then filter the collected results as follows:
From the Grouping drop-down menu in the Bottom-up pane, select the grouping by Process, for example: Process/Function/Thread/Call Stack.
In the grid, right-click the process you are interested in and select the Filter In by Selection option from the context menu.
VTune Amplifier updates the grid to provide data for the selected process only.
From the Grouping drop-down menu, select any other grouping level you need, for example: Function/Call Stack.
VTune Amplifier groups the data for the selected process according to the granularity you specified.
