Introduction to the WPA User Interface
Applies To: Windows 8, Windows 8.1
The Windows® Performance Analyzer (WPA) user interface (UI) consists of a collection of docked windows that surround a central workspace. This central workspace contains Analysis tabs. All windows can be undocked or moved and docked in a different location. To open a closed window, select the window on the Window menu.
The following illustration shows the WPA UI. The Diagnostic Console window is not shown.

Graph Explorer Window
When you open a recording in WPA, thumbnails of all the graphs that apply to that recording appear in the Graph Explorer window, grouped under several nodes. To expand a node, click the small triangle next to the node name.
To see the full graph, drag the graph to the Analysis tab. You can drag multiple graphs to the Analysis tab.
For more information, see Graph Explorer.
Analysis Tab
When you drag a graph from the Graph Explorer window to the Analysis tab, the graph appears together with a Legend control on the left. The Legend control explains the meaning of the lines or bars in the graph. If you want to see the same data in tabular form, click the right-most layout icon on the graph title bar. This opens the associated data table and reduces the graph to a thumbnail. If you want to see both the full-size graph and the data table, click the left-most layout icon.
You can use the right drop-down arrow on the graph title bar to change from a line graph to a stacked-line graph or a stacked-bar graph.
You can use the left drop-down arrow on the graph title bar to select different parameters for the graph, if more parameters are available. For example, you can view CPU usage by process, by CPU, or by process and thread.
All graphs on the Analysis tab share a single timeline. To view graphs that have a different timeline, open another Analysis tab by selecting New Analysis View on the Window menu.
For more information, see Analysis Tab.
Issues Window
If you created the recording in the Assessment Platform, the Issues window lists issues that the assessment identifies. This window is docked on the upper-right corner. If you did not create the recording in the Assessment Platform, this window is minimized because there is no data.
When you click an issue in this window, details for that issue appear in the Details window. All identified issues appear on the Analysis tab below any graphs that you have opened.
For more information, see Issues Window.
Details Window
If you created the recording in the Assessment Platform, the Details window appears below the Issues window in the lower-right corner of the workspace. The Details window provides details about the selected issue and recommended solutions.
For more information, see Details Window.
Diagnostic Console Window
The Diagnostic Console window is docked at the bottom of the workspace. This window provides a list of exceptions in the recording and details related to symbol loading and decoding.
For more information, see Diagnostic Console Window.
