Use the Intel® Energy Profiler tool, provided with the Intel® VTune™ Amplifier for Systems, to analyze power and energy consumption on an Android*, Windows*, or Linux* OS system running on Intel architecture, and identify system behaviors that waste energy. Energy data collection is done using the Intel SoC Watch collector on either the system with VTune Amplifier for Systems installed or on a target system.
Energy Analysis on a Local System
Use the following high-level steps to identify system behaviors that waste energy on a target system (Windows* or Linux* only):

1.
Install the appropriate version of Intel System Studio:
Intel System Studio Professional Edition for Linux
Intel System Studio Ultimate Edition for Linux
Intel System Studio Professional Edition for Windows Target
Intel System Studio Ultimate Edition for Windows Target
2.
Run the data collection with Intel SoC Watch collector.
Data collection can occur on an idle system or run concurrently with a workload that is started at any time during the collection. For more information, see Intel SoC Watch Command Options or the Intel SoC Watch User's Guide (socwatch_<os>_users_guide.pdf), which is located in the \socwatch directory. The Getting Started or Quick Start sections of the guide contain collection commands to get you started.
The result file is saved to the results directory with the following file extension:
Windows* OS: *.sww1
Linux* OS: *.sw2 and *.pwr
3.
Import the results to the VTune Amplifier for Systems project:
Launch VTune Amplifier GUI on the host system.
Open/Create a project.

1.
Install the appropriate version of Intel System Studio:
For a Linux/Android target:
Intel System Studio Professional Edition for Windows Host
Intel System Studio Professional Edition for Linux
Intel System Studio Ultimate Edition for Windows Host
Intel System Studio Ultimate Edition for Linux
For a Windows target:
Intel System Studio Professional Edition for Windows Target
Intel System Studio Ultimate Edition for Windows Target
2.
Copy the collector package from the host system and install the collector:
Configure and run the data collection with Intel SoC Watch collector.
