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.
Prerequisites:
  • 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
