WHAT: Analysis Target

A target is an executable file you analyze using the Intel® VTune™ Profiler, which could be an executable file, a process, or a whole system.
By default, when you create a new project, the
VTune
Profiler
 opens an analysis configuration with the
Launch Application
 analysis target pre-selected:
Configure Analysis: Target
To change a target type for your project, click the Browse button on the
WHAT
 pane. Select from these target types:
Launch Application
Enable the
Launch Application
 pane and choose and configure an application to analyze, which can be either a binary file or a script. See options for launching an application.
This target type is not supported for the Hotspots analysis of Android applications. Use the
Attach to Process
 or
Launch Android Package
 types instead.
Attach to Process
Enable the
Attach to Process
 pane and choose and configure a process to analyze. See options for attaching to a process.
Profile System
Enable the
Profile System
 pane and configure the system-wide analysis that monitors all the software executing on your system.
Launch Android Package
Enable the
Launch Android Package
 pane to specify the name of the Android* package to analyze and configure target options. See options for launching an Android package.
Options available for the target configuration depend on the target system you select in the
WHERE
 pane.
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:
  1. From the
    Grouping
     drop-down menu in the
    Bottom-up
     window, select the grouping by Process, for example:
    Process/Function/Thread/Call Stack
    .
  2. In the grid, right-click the process you are interested in and select the
    Filter In by Selection
     option from the context menu.
    VTune
    Profiler
     updates the grid to provide data for the selected process only.
  3. From the
    Grouping
     drop-down menu, select any other grouping level you need, for example:
    Function/Call Stack
    .
    VTune
    Profiler
     groups the data for the selected process according to the granularity you specified.
If attaching to a running process causes a hang or crash, consider launching your application with the VTune Profiler in a paused state, and resume the collection when the application gets to an area of interest.
