System Analyzer UI Reference

Use System Analyzer tool of the Intel® GPA to monitor your application performance metrics in real time to determine whether the application is CPU- or GPU-bound.
The System Analyzer tool allows you to:
  • Collect various metrics when running your application, or profile your system in the System View mode
  • Analyze the results
  • Perform various "what if" experiments to help isolate performance bottlenecks in your application
  • Capture data for further analysis
  • Export metrics to a CSV file
  • Pause the metrics charts and zoom in and out to get a better view of the metrics
The window is divided into these main areas:

Main Toolbar

Export Metrics to CSV Files
button
Save metric values to a CSV file to post-process the analysis of your application.
Capture Frame
button
Capture and save a frame instantly.
This button is available only when you select
Frame Capture
mode in the Graphics Monitor window and connect System Analyzer to a single host. You can also capture frames using the dedicated button on the
Metrics Control
pane.
Capture Trace
button
Capture and save a trace instantly.
This button is available only when you select
Trace Capture
mode in the Graphics Monitor window and connect System Analyzer to a single host. You can also capture traces using the dedicated button on the
Metrics Control
pane.
Messages
pane
See messages and non-critical errors.
If more than one message is open, use the
Up
or
Down
arrows to navigate between messages.
Enter hostname or IP
box
Connect to a specified host system. Enter a hostname or IP address, and then click the button. You can also get a drop-down menu with a history of recent IP addresses or hostnames by clicking the button.
System Information
box
Get various information about the system running System Analyzer, including the operating system version, hardware information, and system firmware.
Settings
button
Open the
Settings
pane, which contains the following options:
  • With
    Pause mode caching duration (minutes)
    option, set the time frame within which metric values will be preserved in
    Pause
    mode, before the oldest values are discarded.
  • Restore the
    Layout
    ,
    Visible Tracks
    , and
    Track Colors
    to default.
  • Change the color schema of the System Analyzer interface:

    • Dark color schema
  • Adjust the user interface scale:
    • Small
    • Medium
    • Large
Send feedback
button
Send feedback to the Intel® GPA technical support.
Help
button
Get information on navigation controls and opens the Intel® GPA online documentation.

Metrics Control Pane

The
Metrics Control
pane displays a group of hardware, driver, and application metrics used for the analysis of your system or a specific graphics application. For different target systems and workloads, there might be different metrics available. All metrics are subdivided into logical groups as described in Performance Metrics Reference.The
Metrics Control
pane allows you to:
  • Select available metrics from the list, as well as switch between metric sets
  • Instantly capture a trace
  • Instantly capture a frame
  • Select the process to profile
  • Experiment with different rendering techniques to see how they affect your application performance
Type filter expression
field
Filter metrics by name. Save previous search keywords.
Hide inactive metrics
button
Hide all metrics that are not available under the currently selected metric set.
Collapse all groups
button
Close all unfolded groups to the list of connected hosts.
Expand all groups
button
Unfold all groups.
Capture Trace
button
Capture a trace file for the connected host and save the captured trace to the folder specified in the Settings pane of the Graphics Monitor Control panel.
This button is available only when you select
Trace Capture
mode in the Graphics Monitor window.
Select Process
button
Select an available application for analysis or switch to System View mode.
Select Metric Set
button
Switch between different metric sets. This option is only available on systems with Intel® Graphics hardware.
Capture Frame
button
Capture a frame for the connected host and save the captured frame to the folder specified in the Settings pane of the Graphics Monitor Control panel.
This button is available only when you select
Frame Capture
mode in the Graphics Monitor window.
Enable State Override
button
Enable various State Overrides. This option is only available for DirectX* 11 and OpenGL* applications.
Color
boxes
Open the color palette to customize individual track colors.

Metrics Charts Pane

The
Metric Charts
pane can accommodate an unlimited number of charts that visualize the metrics collected by the System Analyzer.
You can customize the System Analyzer
Metric Charts
pane as follows:
  • Display any combination of metrics and instantly switch between different counter sets.
  • Combine multiple metrics with the same measurement unit on one chart by dragging the charts onto each other. For example, the EU Active (%) and EU Stall (%) metrics can be combined since these metrics are represented as percentage. To do this, grab the metric by the tab and drag it onto another chart, or drag a metric from the
    Metrics Control
    pane and drop it onto an existing chart. To remove a track from the combined chart, click the
    Close
    button by the metric name.
  • Change the appearance of each chart by switching between
    Bar Chart
    and
    Line Chart
    modes. If multiple metrics are combined on one chart in
    Bar Chart
    mode, their values are added to each other.
  • Zoom in and out on the charts to get a closer look, using
    Pause
    mode.
Once you customize the chart area, System Analyzer saves your settings and restores them next time you run an analysis.
The pane is divided into two main areas:
Chart Details
panes
Each chart displays a graph for the selected metrics over time. The
Chart Details
pane of each chart provides the following metric data:
  • Metric name and units
  • Minimum value for the visible chart area ("L")
  • Current value
  • Maximum value for the visible chart area ("H")
Metric Charts and Controls
Timeline ruler
Correlate all the displayed metrics with the time line. Depending on the zoom-in level, the time intervals are displayed in seconds, milliseconds, microseconds, on nanoseconds.
/
Real-time Mode/Pause Mode
toggle
Pause the metric charts at any point. When Pause mode is enabled, the System Analyzer shows metric values for the preceding period specified by the Pause mode caching duration option of the Settings pane. In the Pause mode, metric collection continues in the background, and you can zoom in on the charts to get a closer look. Click the button again to resume metric display in real time.
Full Zoom Out
button
Zoom out to get the full view of the metric charts. This button is only available in Pause mode.
Individual chart controls
Hover over any chart to show additional chart controls for each chart:
  • Bar Chart mode / Line Chart mode toggle
  • Close chart
  • Chart scale controls
