MiniUsage displays various data like CPU usage, amount of network flow, battery status and process names which uses much CPU time in a menubar. It takes little space and can display various data, so it's suitable for notebook.
While the application is running, this information can be referred via AppleScript.
If you like this software, I'd like to ask to make small donation to help effort for the Japan earthquake and tsunami disaster.
Added function to display multiple data on menubar.
Ratings and Reviews
Very useful app
My only request would to be able to set the default display stat to be total memory usage as one of the options. Another minor item would be displaying the private/public IP within the network items.
Huge memory and process pig.
The app has some serious memory problems that can cause a system to eventually crash. On my MBP with 8GB, first thing the app does is consume 11GB of virtual memory (THATS RIGHT, 11GB, as reported by top). Every second it runs it chews up 4-8KB of additional physical RAM that it never releases (or at least never released on my system)
Sorry, can not recommend this program except for short-term use. Too bad. I liked it. Hopefully the developer reads this and gets a memory leak checker, and rethinks the architecture. There is no reason why this application can't have a memory footprint 1000X smaller, but the way it is written is a flawed design so it will continuously consume more physical and virtual memory as long as you let it run.
Not only doesn't it get the information directly via system calls (the way you are supposed to do this), but it actually launches internal apps and command-line programs and parses the output to get the answers. This generates so much additional overhead that the program itself skews the results it displays.
If you want to know details then just enter top or ps -ef from command line, and you will get more information then this program supplies for process & memory.
I don’t always write a review… but when I do
Better yet, it’s free and great, so it’s worth a try.
I don’t get memory leaks (monitor via Activity Monitor) and if you want to have it start on login you can customize that in System Pref -> Users -> Login Items, but I haven’t restarted my computer yet, so we’ll see if that’s even needed.
With Family Sharing set up, up to six family members can use this app.
