Figure 18-14: Activity Monitor.
Monitoring Activity
Whenever my Mac or server starts to slow down or act in an odd way, I reach for Activity Monitor in the /Applications/Utilities folder to see what’s going on. Every Mac comes with Activity Monitory.
As Figure 18-14 shows, the bottom part of the Activity Monitor screen lets you view memory, CPU, and disk usage, as well as how much network traffic is going into and out of the server. Although the Server app is good for identifying trends, Activity Monitor is good for telling you what’s going on right now.

Most of the Activity Monitor window is taken up by a list of currently running software processes. You can list these processes in order of the amount of processor or memory they’re using by clicking the corresponding column head. Activity Monitor can help you find processes that you didn’t know were running and might not need.
