Intel® VTune™ Amplifier uses kernel drivers to enable hardware event-based sampling and collect event-based sampling data from. During the hardware event-based sampling (EBS), also known as analysis in the sampling mode, the Intel® VTune™ Amplifier profiles your. To enable hardware event-based sampling analysis on your platform, the Intel® VTune™ Amplifier uses sampling drivers that require root.

Prerequisites for remote target systems: When the filtering is vtunf, the collector gathers data only for the processes spawned by the user who started the collection. The tool can be also used to analyze thread and storage performance.

Using this access the user can profile the system, an sapling, or attach to a process. For example, your operating system limits on the maximum amount of files opened by a process as well as maximum memory mapped to a process address space still apply and may affect Perf-based profiling. The smaller the sampling interval, the larger the number of samples collected and written to disk.
