Frequently Asked Questions
How do I install the Sampling Drivers?
When you install VTune Profiler , the installation process should also install the required sampling drivers you require for data collection, as long as you complete the process with appropriate permissions (administrative/root/sudo access). Drivers are also installed on a target system when VTune Profiler connects to the target system during analysis configuration (administrative/root/sudo access required via a password-less SSH connection). If the drivers fail to install, you can configure them manually.

NOTE:
Occasionally, updates to supported operating systems can cause the sampling drivers to fail during building or loading. In this case, before you update Intel® VTune™ Profiler, you may need to download the latest versions of the sampling drivers and manually build the drivers.
What features are available for a non-root or non-administrator user?
Windows* OS
On a Windows machine, when you install and launch VTune Profiler as a regular user, the analysis types that employ User-Mode Sampling are available:
- Hotspots analysis (without microarchitecture performance insights)
- Threading analysis
- Memory Consumption analysis
Linux* OS
On a Linux system, VTune Profiler can use the capabilities of the Linux Perf* utility to deliver several features, without requiring sampling drivers and/or root privileges. Certain considerations, prerequisites, and configuration steps apply to the use of Linux Perf.
