the submenu. To rename, reorder, or delete existing column sets, choose Organize Column
Sets from the View menu. Reordering the column sets changes the order in which they
appear in the Load Column Set submenu and the accelerator keys assigned to them.
Note The saved column set accelerator keys assigned by Procexp conflict with the default
hotkeys used by ZoomIt, described in Chapter 10, “Desktop Utilities.”
Saving Displayed Data
Click the Save icon on the toolbar to save a snapshot of current process activity to a text file.
Procexp saves the data from all the columns that are selected for display in the main window,
and in the lower pane if it is open, to a tab-delimited text file. If a file has not already been
selected, Procexp prompts for a file location. To change the file location, choose Save As
from the File menu.
Toolbar Reference
The Procexp toolbar includes buttons for quick access to frequently used features, and four
or six continually updated graphs displaying the recent history of systemwide metrics.

Graphs
The minigraphs in the Procexp toolbar can be resized or moved to separate rows by dragging
their left-edge handles. Procexp displays graphs representing CPU usage, commit charge,
physical memory usage, and file and device I/O. If Procexp is running with administrative
rights, it adds graphs for network and disk I/O.
The CPU graph shows recent history for systemwide CPU usage, with red showing kernel
usage and green showing the sum of kernel-mode and user-mode usage. The systemwide
commit charge is shown in the yellow graph and physical memory usage in the orange
graph. Recent systemwide I/O throughput is graphed with violet for writes and light blue for
all I/O. Moving the mouse over the graphs displays a tooltip with numeric details and the
time of day for that part of the graph, and for the CPU and I/O graphs it displays the process
responsible for the largest proportion of the CPU or I/O at that moment. The wider you
resize a graph, the longer the timeframe it displays. Clicking on any of the graphs displays the
corresponding graph in the System Information dialog box. (See the “System Information”
section later in this chapter for more complete descriptions of the meanings of these graphs.)
