Hardware Event List

You can customize the list of PMU events monitored by the Intel® VTune™ Profiler for your processor by modifying an existing or creating a new hardware event-based sampling (EBS) analysis configuration.

To add events:

  1. In the HOW pane, select an existing hardware event-based analysis (for example, Microarchitecture Exploration) and click the Copy button to create a custom copy of this configuration.

    The new analysis type shows up under the Custom Analysis group in the HOW pane.

  2. From the list of PMU events supported for the current platform, select the events you want the VTune Profiler to monitor in your new configuration.

    • To narrow down the list of available events, enter a search keyword in the Filter field. This applies to both the Event Name and Event Description columns.
    • To learn more about an event, select it and click the Explain button to view the description in the Intel Processor Event Reference.
    • To deselect all currently selected events, click the Deselect All button. You can also use Ctrl+Click or Shift+Click to adjust your selection. The button is disabled if no events are selected.

    Note

    Typically precise events have a _PS postfix (for example, UOPS_RETIRED.RETIRE_SLOTS_PS) and/or a clear indication (Precise Event) in the Event Description column.

  3. Click Start to run your new analysis configuration.

Note

You may configure the VTune Profiler to monitor all the events in a single collection run using event multiplexing or allow multiple runs to collect more precise event data.
