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
>
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

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
