Activity Monitor In Your Dock

Most Dock icons are just plain icons. But try running Activity Monitor, and app found in your Applications/Utilities folder. The Dock icon can show you graphs and charts relating to the activity on your Mac. Control+click on the icon and choose an option under Dock Icon to change what information is pictured. You must keep Activity Monitor running for the icon to update, but you can hide it.
