Platform Profiler Results (Preview)

Note

This is a PREVIEW FEATURE. A preview feature may or may not appear in a future production release. It is available for your use in the hopes that you will provide feedback on its usefulness and help determine its future. Data collected with a preview feature is not guaranteed to be backward compatible with future releases. Please send your feedback to parallel.studio.support@intel.com or to intelsystemstudio@intel.com.

Use the Intel® VTune™ Amplifier Platform Profiler to gain insights into overall system configuration, performance, and behavior. Platform Profiler collects metrics on CPU, memory, network, and disk usage over a longer collection interval than other Intel VTune Amplifier analysis types.

Upload Results

To review the performance data provided by Platform Profiler, start by uploading the results.

Upload using user interface:

  1. Start Platform Profiler.

    Note

    If you have not used the Platform Profiler user interface since installing Intel VTune Amplifier, some initial setup is required. For details, see Platform Profiler Setup.

    • On Linux*:

      1. Run the following commands to start Platform Profiler manually after initial installation or a system reboot:

        source ./vpp-server-vars.sh
        vpp-server-start
      2. Navigate to the Platform Profiler home page in your browser (Google Chrome* recommended): http://localhost:6543

    • On Windows*:

      1. Launch Intel® VTune™ Amplifier and open or create a project.

      2. Click the Configure Analysis button on the Intel® VTune™ Amplifier toolbar.

        The Configure Analysis window opens.

      3. From HOW pane, click the Browse button and select Platform Profiler from the Platform group.

      4. Click the Launch button to launch and open the Platform Profiler home page in your browser.

  2. Click View Results.

  3. Click the Upload button and select the result file to upload.

    Note

    If you collected results on a different system, you may need to copy the results to the system on which Platform Profiler is installed.

Upload using command line:

  1. Open a command prompt and navigate to <vtune-install-dir>/vpp/collector

  2. Run the following command:

    On Linux:

    source vpp-collect-vars.sh

    On Windows:

    vpp-collect-vars.cmd
  3. Run vpp-collect-upload <path-to-dataset>

  4. Follow the instructions on the command prompt.

Interpret Results

Select a result from the list to open the viewer.

The result opens at a machine-level view. Analysis of the data is available at multiple topological levels, such as machine-level overview, socket-level, core-level, I/O view, memory view, or UPI/QPI view. The example below shows a machine-level overview for a two socket system.

  • The timeline allows you to filter on a smaller range of collection time.

  • Hover over the topology diagram to get quick metrics for each subsystem.

  • Click an area of interest in the topology diagram or select from the Select View drop-down list to focus on that subsystem (socket, core, memory, disk, etc.).
