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.
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
What's Next
When the data collection is complete, do one of the following to view the result:
Use the -report action to view the data from command line.
Use the -report-output action to write report to a .txt or .csv file
Open the data collection result (*.vtune) in the VTune Profiler graphical interface.
