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:
$ amplxe-cl -collect system-overview [-knob <knobName=knobValue>] -- <target>
Knobs: sampling-interval, collection-detail.
For the most current information on available knobs (configuration options) for the System Overview analysis, enter:
$ amplxe-cl -help collect system-overview
Example:
The following example runs the System Overview analysis on a guest OS via Kernel-based Virtual Machine with specified kallsyms and modules files paths.
$ amplxe-cl -collect system-overview -analyze-kvm-guest -kvm-guest-kallsyms=/home/vtune/[guest]/kallsyms -kvm-guest-modules=/home/vtune/[guest]/modulesWhen 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 (*.amplxe) in the VTune Amplifier graphical interface.
