CPU Monitor

After looking at software updates and backing up data, we'll round out our system management discussion with a discussion of system resources. With the multitasking capabilities of Mac OS X, you find it interesting to check just how much of your computer's processor time is being used. In Mac OS X, each program has a small slice of time it can use to complete its task. As more and more programs use the system, there are fewer slices to give out.

CPU Monitor, found in the Utilities folder of the Application folder on your hard drive, can illustrate how busy your system is on a simple graph, showing a range from 0% to 100%. (If you have a computer with multiple processors, a graph is displayed for each CPU in your machine.) Three types of graphs can be displayed in a number of different ways (configurable through the Preferences panel and Processes menu). Figure 28.5 shows several available graph styles.
