"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!

- 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.

Brilliant little app
I bought the memory add on as in particular I wanted to be able to easily see when memory was becoming critical and also when pagins were happening too much and it does both. I use my macbook for development, it is running all sorts of stuff, including VMs and it can get bogged down, especially when kernel_task decides to grow its self to several gigs, and performance starts to degrade. This little app lets me keep my eye on the state of things, so I know when I need to start closing stuff down, before performance becomes a problem. It should also help determine when there is nothing for it, but a reboot - to reclaim memory from OSX.
The only thing I would like to improve is to be able to increase the pagein indicatior size its a bit small, or better yet have an option for it to flash the memory indicator (so it works like a disk LED) and the off condition indicates memory usage.
Briliant, used everyday!
Downloaded this app a few months ago and have used it daily ever since. I typically use to have activity monitor open all the time and since having this app I have had less need for activity monitor. I constantly want to monitor my computers performance and the neat design of this app does exactly what I want it to do. It shows my cpu load without any trouble and is not distracting from tasks being carried out daily.
Recommend to all!
caused errors in strange places...
using a 2014 macbook pro, had a problem getting an audio interface to work, was experiencing keyboard and trackpad freezes amongst other funny buisenss going on when trying to use the interface, took it to Apple and they found I was getting a huge stream of errors to do with my SMC chip (governs the voltages etc in USB ports apparently)
After looking around they tracked down the source of the errors to a software problem (the geniuses ruled out hardware), I started playing around and quit this application, problem solved, no errors in the console, and apparently my audio interface is back up and running… turned it back on and the errors in the console returned
in short, a very strange place to get errors from, but safe to say i wont be using it anymore!
Up to six family members will be able to use this app with Family Sharing enabled.
