Intel® VTune™ Amplifier XE and Intel® VTune™ Amplifier for Systems Help

Driverless Event-Based Sampling Collection

To run hardware event-based sampling analysis types, the Intel® VTune™ Amplifier uses sampling drivers that require root privileges for installation on the Linux* and Android* systems. If, for some reasons, the sampling drivers cannot be installed (for example, you do not have root privileges on the system) with the product installation, the VTune Amplifier may try to use the Perf* utility and run the hardware event-based sampling analysis in the driverless mode.

VTune Amplifier can use the driverless Perf-based collection if the following requirements are satisfied:

Note

Perf-based driverless collection can be used for running Advanced Hotspots, General Exploration and Custom event-based sampling analysis types on Linux and Android OS. If the uncore events support is available on the system, the VTune Amplifier may also use the Perf collection for Memory Access, HPC Performance Characterization and General Exploration analysis types with the Analyze memory bandwidth option enabled.
