"CPU LED is a fantastic little menu bar tool for keeping an eye on your CPU load. [...] So if you're at all concerned about your CPU load and you've got space to spare in your menu bar, give CPU LED a whirl. " (Samuel Gibbs - TUAW)
Do you ever wonder how stressed your CPU is? Sometimes, opening a complex activity monitor while your computer is heavily loaded is too late (or too much). Sometimes all you need to know is that your CPU is working hard.
CPU LED is a very lightweight unobtrusive app that adds a LED in your status bar indicating your CPU activity (coded as light, medium or hard). You can have only one light for all your processors or one per core (your choice). You can also choose the status icon appearance so it blends nicely with your status bar style, and hover with your mouse over the leds to see the current usage % and core temperature.
In order to know what is going on with your computer at a glance, CPU LED is the perfect companion for Disk LED!
See it for yourself.
And if you are using Mac OS X 10.7 Lion, you can also upgrade CPU LED by adding Memory LED!
That small guy will show you how much of your RAM is occupied (LED style), and how much paging is happening (i.e.: RAM to Disk and Disk to RAM operations). Too much paging means your performance is going down the sink...
Now you know how to solve those uncomfortable "I switched apps and my machine is dying" moments! When Memory LED shows that you are running out of memory, just close some programs and you are good to go!

What's New in Version 1.3
- Now the four status icons are used to display CPU load.
- Hide status icon for disabled CPU cores.
- Fixed crash when loading a custom icon set for CPU status.
- DiskLED addon: fixed some external devices didn't disappear when unmounted if "Ignore devices that doesn't contain any media inserted" is enabled.
Does what it says, but can be very badly behaved
I used this app since January 2012, when I bought an 8 core MBP and found I could no longer see each core's load in the activity monitor dock (it shows just one bar if you have any more than four cores.) I'm a programmer and I like to see if one of my cores is pegged (usually because I screwed something up.)
So I found CPULed. It's done a reasonable job since then, taking up little room in my menu bar and showing me CPU activity in a neat and reasonably attractive way. The problem is, it's become flaky. When I try to restart the Mac tells me "CPULed cancelled restart." (It restarts anyway.) If I try to quit it, it won't quit. Ever. I can't access its preferences. More recently, I've noticed Finder gradually using up to 100% CPU after an hour or so of uptime; I kill Finder, it creeps back up. I went through all my programs, extensions, plugins and other thingumajigs until I finally stopped CPULed running on startup. Sure enough, Finder is back to normal. All this on Lion, by the way.
I don't necessarily blame CPULed for this. After all, when I first installed it I could open its preferences, I could quit it, and it didn't cancel restart. It was the perfect little app. Finder behaved well too. Maybe it's fought with something I've put on more recently? I don't know. All I do know is that this particular luxury has been uninstalled.
Great app but...
So ill start off by saying that I love this application. It does what it sayse and helps me know when my cpus are working hard. This then gives me a heads up as to start slowing things down a bit to give the cpus a break. However I have found one problem with it that is very irritating for me. In the preferences panel I have checked "start at login", however when ever i go away from my computer and shut it down or even let it go to sleep it wont let me access the preference panel from the menu bar, so I have to go to my applications folder and then "open" it again even though it is already open. Please fix this I dont have any other complaints than this.
Thanks for you time,
the spacing is usually off with the "space them out" option on, witch makes them much easier to read.
also, and here's the kicker, it occasionally hangs and sometime even cancels my system's shutdown, (to which my system tells me, then shuts down after a few seconds anyway).
Considering all this thing does is sit in a corner and look pretty, and I have had it for months, I never really notice it until it acts up.
I'm not sure it's worth installing, I'm pretty indifferent to its presence on my mac right now.
