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 ofVTuneand results are viewed in a web browser.Profiler
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,VTunecan work on Perf* (driverless collection).Profiler
- To enable system-wide and uncore event collection, use root or sudo to set/proc/sys/kernel/perf_event_paranoidto0.$ echo 0>/proc/sys/kernel/perf_event_paranoid
