    This version of PerfInsights has the following requirements :
    1. PerfInsights must be executed on the VM that has the performance issue.

    1. Download the PerfInsights.tar.gz file to a local folder on your linux virtual machine and extract the archive.
    2. Navigate to the folder that contains the perfinsights.py file and run PerfInsights script from the terminal
      • sudo python perfinsights.py

    Sample command line:
    sudo python perfinsights.py -r quick -d 10s -o /tmp/output

    When the execution is complete, you will see a link to the report output in a file called: PerformanceDiagnostics_YYYY-MM-DD_HH-MM-SS.tar.gz. Extract the archive and open PerfInsights Report.html file. You can find various logs collected under output/guestosfiles folder.
