Is there any easy way to get CPU usage on a per core basis at a certain interval throughout the day? (e.g. every 60 seconds) Notes - happy to use a script (e.g. ruby, python) and run it in the terminal - would be great if the output were a simple csv, but open to using more sophisticated tools/outputs if they exist and are easy to use - the ultimate goal is to take to plot a time series of per-core utilisation over the day (or week/month) (that is, a line chart with as many lines as cores) - The answer on https://apple.stackexchange.com/questions/94900/get-cpu-usage-per-core-on-the-command-line/ can't be used in a loop Example output: A csv that resembles:

time, core_1, core_2, core_3, core_4 (etc)
"2020-07-18 15:45:00 UTC", 15%, 12%, 0%, 1%
"2020-07-18 15:46:00 UTC", 100%, 100%, 10%, 3%
"2020-07-18 15:47:00 UTC", 10%, 2%, 0%, 0%
etc etc

I already know how to view network activity [using Activity Monitor](https://apple.stackexchange.com/a/121377/290197) . But today I saw someone with network statistics [displayed in the menu bar](https://www.youtube.com/watch?time_continue=126&v=H5i1gdwe1Ls) : How is this achieved?

I see the latests Macbook Pro 16" has a [100 watthour battery](https://www.youtube.com/watch?v=E92TnPdDgEU#t=3m30s) - how do I find the equivalent stat for my current Macbook given the info under About -> System Report -> Hardware -> Battery Information? My guess is take the full charge capacity (3582). Also divide the mV (milli volts?) by 1000 to get volts, then use a calculator or [conversion table](https://www.thecalculatorsite.com/conversions/common/watts-amps.php) . But I'm not exactly sure what to do next?

I want to know how many users there currently are for each iPhone model and in which countries each one is used. For instance- World users for: ---------------- iPhone 8 = 411,912,030 iPhone X = 1,120,498,232 iPhone XR = 790,875,338 iPhone 11 = 429,938,274 iPhone 11Pro = 317,483,584 _________________________ UK users for: iPhone 8 = 1,912,030 iPhone X = 6,498,232 iPhone XR = 7,875,338 iPhone 11 = 9,938,274 iPhone 11Pro = 3,483,584 _________________________ USA users for: iPhone 8 = 13,912,030 iPhone X = 29,498,232 iPhone XR = 37,875,338 iPhone 11 = 49,938,274 iPhone 11Pro = 33,483,584 __________________________ Australia users for: iPhone 8 = 912,030 iPhone X = 1,498,232 iPhone XR = 2,875,338 iPhone 11 = 3,938,274 iPhone 11Pro = 4,483,584 Is there a way to find this information out? Obviously I would like the data to update every now and then.

It seems that only iostat were available on mac. But I am looking for more comprehensive set of stats including cpu, memory, and network. What are the options here?

I am looking for an app similar to conky on Linux that will allow me to display various system stats and style them right on my desktop wallpaper. I am only able to find things like iStats which have menubar interactive items but I don't really want that, but something that will allow me to put various stuff right on the Desktop. Does this exist? Something like this

I'd like to setup my own statistics site for my own released apps. I'm just wondering, if it's possible to have an iTunes Connect API where I can fetch all statistics from the iTunes Analytics area like downloads, crashes, paid applications, active users, in app purchases, etc. This kind of question was already asked a couple of years ago (around 2015) but without any appropriate answers. Just to be clear: I'd like to build my own dashboard and I'm not asking for an export functionality (e.g. xls, csv, etc.) or where I can find some other tools.

I have over 200 apps on my iPhone 4 (32GB). No one *needs* that many apps, right? **I want to organize my installed apps based on how frequently I use them, and/or how recently I last used them.** I could probably take a qualitative, subjective stab at this myself, but I'd like to have some data, just so I don't toss an app that I may have used, but don't remember using. Yeah, I know that *deleting isn't forever* with apps-- but having geeky data makes me feel good. So far, I have not found a way to do this. I've seen apps mentioned here on AskDifferent that purport to do such a thing, but have not tried any of them. For some reason, I seem to recall Googling this several months ago, and running across an article describing a way to glean usage information from the backup file(s) that iTunes creates. I can no longer find that article-- not sure if it's *gone* or if I'm just not using the same search terms as before. Note that my iPhone is *not jailbroken*, nor do I wish to jail-break it. I'm not necessarily even interested in an iOS *app* that gets me this information; I'm simply interested in it any way that it can be had. If that is via Terminal on the desktop, that's fine. Knowing this kind of usage information would also be objectively useful if I'm trying to implement some kind of app/folder organizational strategy . Otherwise, I'm left to my own intuition about how often I use things, which can be false, or in the least, inefficient.

So let me preface my image by saying I have made ~20 seconds of phone calls in the past 24 hours. After heavily browsing the web in 1-2 bars of LTE coverage for a few hours, I looked at my battery usage statistics and saw the following. What's the deal here? This is iOS 10.1.1 on an iPhone 7 on AT&T.

I check my app downloads on AppAnnie. Today I've seen that the number of updates is greater than the number of downloads ... how can it be possible ? Let's say the first version of an app is downloaded 100 times. If a new version is released and only 50 user updates to the new version than the two numbers become: 100 downloads and 50 updates. Now, if 100 new user download the app (they can only download the new version) the numbers become: 200 download and 150 updates. I cannot understand how the number of updates can become greater than number of downloads (probably I've not clear which is the exact meaning of the two numbers).

I was wondering if anyone knew of a way to get more information on the syncing process - i.e. speed of the transfer, MB remaining, estimated time, etc. I ask because I was syncing some iTunesU files which are pretty big - 3.2GB - over Wi-Fi, and thought it would be useful to know exactly how quickly they're being transfered, and how much I've got to go. All there is normally is a bar that slowly fills up. Surely there's a way to access this info, perhaps in a terminal window?

When looking at usage stats in iOS (data sent/received), are the megabytes/gigabytes in base-10 or base-2? The docs are not entirely conclusive (since it doesn't address usage specifically) but suggests base-2 is used for iOS device capacities. So which is it?

I'd like to buy a mobile broadband service, but there's a limit in gigabyte per month I can download. Before i buy, it would be great to know what i currently consume, bandwidth wise. Is this statisti available anywhere on a vanilla OS X system? Should I get an additional application?

I'm looking for an iOS program that can calculate some statistics for me. I want a program into which I can enter a bunch of observations, then the program uses multivariate linear regression (ordinary least squares) to find coefficients and standard errors for the line of best fit. I know of plenty of programs that do this on the Mac, but not any iOS programs. There aren't any programs in the app store that list this as one of their key features, but I didn't know if it was an additional feature in something like Numbers. Alternately, while I'd prefer not a web app, that's certainly better than not having an app to do this. A web app that uses local storage so it can run even when offline would be best. Any suggestions?
