- Configure Yocto Project*/Wind River* Linux* and Intel® VTune™ Profiler with the Intel System Studio Integration Layer
Platform Analysis Group
The Platform Analysis group introduces analysis types monitoring system behavior and power usage for your application/system.
System Overview is a driverless event-based sampling analysis that monitors the general behavior of your target system. Use this analysis to identify platform-level factors that limit performance, including power usage and throttling.
Platform Profiler analysis collects data on a deployed system running a full load over an extended period of time with insights into overall system configuration, performance, and behavior. The collection is run on a command prompt outside of VTune Profiler and results are viewed in a web browser.
For best results, install the sampling driver for hardware event-based sampling collection types. For Linux* and Android* targets, if the sampling driver is not installed, VTune Profiler can work on Perf* (driverless collection).
To enable system-wide and uncore event collection, use root or sudo to set /proc/sys/kernel/perf_event_paranoid to 0.
$ echo 0>/proc/sys/kernel/perf_event_paranoid
