system-overview Command Line Analysis

System Overview analysis evaluates general behavior of Linux* or Android* target systems and correlates power and performance metrics with IRQ handling. This analysis type uses the driverless event-based sampling collection.

Syntax

vtune -collect system-overview [-knob <knobName=knobValue>] -- <target>

Knobs: collecting-mode, sampling-interval, enable-interrupts-collection,analyze-throttling-reasons.

NOTE:

For the most current information on available knobs (configuration options) for the System Overview analysis, enter:

vtune -help collect system-overview

Example 1:

This example runs the System Overview analysis on a guest OS via Kernel-based Virtual Machine with specified kallsyms and modules files paths.

vtune -collect system-overview -analyze-kvm-guest -kvm-guest-kallsyms=/home/vtune/[guest]/kallsyms -kvm-guest-modules=/home/vtune/[guest]/modules

Example 2:

This example runs the System Overview analysis for the matrix application in the low-overhead hardware tracing mode.

vtune -collect system-overview -knob collecting-mode=hw-tracing -- /root/intel/vtune/sample/matrix/matrix
