Watch CPU Load and Activity – Mac Kung Fu, 2nd Edition

Tip 135Watch CPU Load and Activity

To have a small floating window appear showing CPU activity at the present time, start Activity Monitor (Open Finder, select the Applications list, and then double-click Activity Monitor within the Utilities folder), and click the Window menu. Then select Floating CPU Window, and choose from either horizontal or vertical displays. The floating window will appear at the bottom left of the screen, and you can click and drag to move it around.

On most modern Macs, you’ll see two, four, or more charts, representing each of the cores in the processor. If you’re using a high-end Mac Pro system, you might have up to sixteen processing cores and therefore sixteen bar charts!

To get rid of the graph, select None from the Floating CPU Window menu.

To see a graph showing the CPU load over time, select the CPU History entry from the Window menu. To get rid of it, just click the Close button on the window.

For examples of the various CPU load graph types, see Figure 23, Graphing CPU load.
