Add fake transparency to Activity Monitor's Dock icon Apps
Monitoring your system's processor activity can be very important, and OS X has a great monitor utility called Activity Monitor built in that you can use to kill/tweak processes and monitor network, CPU, RAM, and hard drive use. Once the monitor is running, you can right click on its icon in the Dock, select Dock Icon » Show CPU History, and have your CPU activity show right in the Dock. However, the default background of the dock activity tracker is black, making it plain you're looking at a box; this makes it not quite fit the smooth look of the rest of the Dock. You can change the colors, though, and even make it have what seems to be a transparent look. To do this, fire up DigitalColor Meter and Activity Monitor; both are in your Applications » Utilities folder.

In DigitalColor Meter, change the sampling to RGB as actual value 8-bit and put your cursor right next to the Activity Monitor dock icon. Press Command-L to lock that location in DigitalColor Meter. In Activity Monitor, click the CPU tab, and then click the black box next to "% Idle." Select the RGB sliders tab (the second tab) of the Color window, and enter the RGB values displayed in DigitalColor Meter.

[robg adds: This isn't true transparency, of course, just the appearance of transparency. I use MenuMeters to track CPU usage, as the meter is always visible in the menu bar and I keep my dock hidden.]

iStat also has a menubar system monitor available which is UB.

Yeah, iStat Menus replaced my MenuMeters a while back -- they're totally cool. :)

Open Activity Monitor, click the button next to "Idle" to get the Color Palette, as in the hint.

Then, click the magnifying glass on the Color Palette which will let you select a color from anywhere on the screen. Click in the dock just by the Activity Monitor icon, and voila.

Note that keeping Activity Monitor going on a permanent basis isn't really such a hot idea, as it consumes quite a few processor cycles itself. Best to use it to see what's causing problems and then shut it down until you actually need it again.

That might very well be possible, therefore reducing the sampling frequency to the minimum (*) should be good advice if you plan to keep it running permanently.

(*) ie, setting the sampling interval to the maximum.
