uses kernel drivers to enable the
hardware event-based sampling
installer automatically uses the Sampling Driver Kit to build drivers for your kernel with the default installation options. If the drivers were not built and set up during installation (for example, lack of privileges, missing kernel development RPM, and so on),
provides an error message and, on Linux* and Android* systems, enables
driverless sampling data collection
based on the Linux Perf* tool functionality, which has some analysis limitations for a non-root user.
also automatically uses the driverless mode on Linux when hardware event-based sampling collection is run with stack analysis, for example, for Hotspots or Threading analysis types.
