Ruby gem for your mac stats

iStats

iStats is a command-line tool that allows you to easily grab the CPU temperature, fan speeds and battery information on OS X. If you'd like to see more data available feel free to open an issue.

Installation

$ gem install iStats

Note

If you are running an older version of OS X and the install fails you might want to try running this command instead:
sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install iStats

Advanced usage

iStats now supports extra sensors for advanced users. Here's how to enable that functionality:

1. Run istats scan to scan your computer for SMC sensors
2. Enable extra sensors by running istats enable key or istats enable all
3. Run istats or istats extra to see the extra sensors information.

Zabbix Integration

iStats has a "scan zabbix" mode which will emit JSON suitable for use with Zabbix low-level discovery. See the accompanying template and agent config in the integrations directory.

istats's Issues

battery info seems quite slow on my Yosemite mid 2009 mbp with an HDD.

Every time when I run istats, all information but the battery stats appear quickly. But for each battery info, it takes ~0.5 seconds for each item to appear.

When I dig into the source, I got a lot of ioreg -l | grep some_keyword in battery.rb. When I run time ioreg -l >/dev/null in bash, I got:

real    0m0.552s
user    0m0.109s
sys 0m0.312s

This is quite close to the delays between each item. It seems that first caching the output as a variable to store internally and then use ruby builtins to match regexes may be a better idea, since ioreg is really, really slow…

Host is down

I get an error trying to install iStats.

On High Sierra:

    Host is down - send(2)

On Sierra:

newbie question about download and installation

I wanted to download your program and use it on my 2011 macbook pro (running High Sierra 10.13.6), but it's not exactly clear to me what I'm supposed to do or in what order in order to get it working. I am VERY new to tinkering around with my mac, new to programming, and new to github, etc so please forgive the ignorance! ANY help or guidance you'd be willing to offer a newbie would be greatly appreciated!

If it helps with context, what I did try downloading the files and running the installation command in a terminal window, but I received the following message:

If you're not sure how to help get me going or don't have the time, at a minimum I would definitely appreciate it if you could let me know which leftover files/folders from the failed installation are specific to iStats so I can clean them out in the event I can't get the program up and running. Thank you!

lzma was install through the xz formula via brew. This error is produced with and without ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future

Update README with alternate instalation for OS X

One can circumvent the xCode Ruby bug by using the following command to install iStats

sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install iStats

Feature request:Fan control

I know that there are already programs for that , but if we add ability to control fan speed to istat + daemon mode it will make this tool much more usefull.

Misreporting CPU temp

I've installed iStats on a mid-2007 iMac that runs OS 10.9.4 and does not use Homebrew. There are two odd bits:

1. the reported CPU temperature is -127.0 C -- great for condensed matter physics experiments! :p
2. fan 0 always reports 0 RPM (I note that this may be a hardware issue.)

The installation went like so:
$ \curl -sSL https://get.rvm.io | bash -s stable --ruby
$ rvm use system
$ sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install iStats

Documentation installation errors

Had some errors installing, I think with documentation only.

Feature request: set command to cpu temp

In my opinion it's much better to be able override that TC0P easily .. ex istat cpu set TC0D

cycleCount or cycle_count

Originating in 879bda3, the help and readme suggests istats battery cycleCount while command.rb requires istats battery cycle_count, so naturally the former fails while the latter works. Raising an issue rather than PR to decide which to prefer, as this the only two-word option.

Feature request: GPU temp

Will be good to have some info about GPU temp, its actual to those who has dual graphics macbook.
thanks

different CPU temp to Intel Power Gadget

https://software.intel.com/en-us/articles/intel-power-gadget-20 gives CPU temperature values that are approx. 22ºC warmer than what iStats reports.

Hardware:
Macbook Pro 13" retina mid 2014, Core i5 (I5-4278U)

naming convention (suggestion)

Not an issue.

iStats is not a conventional name in ruby and not a common name for gems
I kept looking for 'istats' (all lower case).
Don't know if this matters to you, but I'd suggest making the name more discoverable.
Up to you, the beauty of ruby is that it doesn't enforce style.

In any case, beautiful gem. I was looking for something just like this. :)

istats scan -f shows all meters as critical

Thanks for all of your work on this program. It's great.

if run istats scan -f the meters seem to use the Fahrenheit temperature for the meter, which makes them all appear critical, when they're actually fine.

Same is true if I enable a key, the extra meter changes colors depending on whether I use the -f flag (though the default meters are fine)

$ istats -v
iStats v1.5.1

Slight issue with iStats and Watch

I thought i would use iStats with the watch command so i would get a real time tempature update every -n X seconds. Thou using the watch command i get the text read out, the ncurses graphics do now show up well or at all.

command used:
watch -n 10 iStats

[iMac] CPU temp: -127.0ºC

First of all, really nice project! Congrats man.

I think it isn't identifying the correct CPU sensor for my iMac. Maybe TC0C?

Machine info:

Just downloaded and upgrade to 10.11.1 El Capitan and now i cant seem to iStats in terminal, is this a known issue?

Install fails on Snow Leopard

I'm trying to install iStats on Snow Leopard. This may not even be possible, but I'm checking with you anyway.

I'm getting the following errors:

Building native extensions.  This could take a while...
ERROR:  Error installing iStats:
    ERROR: Failed to build gem native extension.

and down the stack trace:

smc.c:397: error: ‘kIOPSTimeRemainingUnknown’ undeclared (first use in this function)
smc.c:397: error: (Each undeclared identifier is reported only once

make failed, exit code 2

I'm using ruby 2.1.2 on OS X 10.6.8. Any idea what might be causing this?

Feature Request: Parameter to exclude colors in output

I would like to run and log the values of IStats watching the command every 5 mins.
The output contains color values that are only interpreted by the shell:

Would it be possible to exclude those color chars from the output?

Sorry if this is not the way request a feature.
Thanks!

no temps reported

just installed on a 2010 mac pro via gem . istats totally gets the fan speeds , which is dope , but reports 0.0C for (the only) cpu temp ... which seems wrong . but i'm gonna write a munin plugin to graph cpu and fan stuff right now anyways and hope that a fix can be found . i assume this is something w/ ioreg , but i haz no time right now to understand it .

--timball

ps) please ignore the terrible cut&paste job . my fonts terminal fonts are a bit wonked out .

any help will be appreciated, thank you!

Help output bug ("set" instead of "enable")

Hi!
Here it says "set" and should be "enable". Took me a couple of minutes to figure out.

https://github.com/Chris911/iStats/blob/master/lib/iStats/smc.rb#L120

#include guard in smc.h doesn't prevent including twice

smc.h currently has an include guard at the top in this format

#ifndef __SMC_H__
#define __SMC_H__
#endif
<code>

This does nothing.. If it's included again, it will still include all the code, just not redefine __SMC_H__

It should be like this:

#ifndef __SHC_H__
#define __SMC_H__
<code>
#endif

This will ensure the header is only included once.

Add switch for fahrenheit outpout

Just a suggestion for american users, can you please add a Fahrenheit conversion switch.

Not working on El Capitan public beta

I had iStats installed in Yosemite, but when trying to run it in El Capitan I get command not found.

I tried installing it again and this is the output I get

sudo gem install iStats

Problem on case-sensitive file systems

In bin/istats, you need require 'iStats', not require 'istats', to have this work on a case-sensitive file system.

No such file or directory - ioreg

iStats was working fine and all of the sudden I started getting this error. Any suggestions?

Check if there's a battery on system (macbook). If not, print "No Battery" in the battery stats section instead of showing "unknown" messages.

was working fine - noticed line on executing
Ignoring iStats-1.6.1 because its extensions are not built. Try: gem pristine iStats --version 1.6.1

so I tried to run "gem pristine iStats --version 1.6.1" and now it's broken.

Fan speed reading is way off

Hello there,

I noticed that when I use istats on my new MacBook Pro 15 2018, the fan speed seems way off.

Please let me know what do you find.

more temps?

it is possible to add more temp sensors, like in this image of http://www.tunabellysoftware.com/tgpro/?

thanks!

Battery Temperature reading from ioreg [Idea/Discussion]

Hi,

This is not really an issue with iStats it is just something i noticed and i thought that you are the guy to discuss this with.

I was curious about the battery temperature on my mac, and came across iStats (thanks for your work on it!). Reading the source code i noticed it uses ioreg -rn AppleSmartBattery for some measurements (i.e. capacities and cycles).

ioreg -rn AppleSmartBattery also returns a Temperature reading. Somewhere else i saw that the value is read as it was in Celsius * 100.

But that seems not quite in agreement with the iStats battery temperature, that as far as i can tell is read using SMC and the TB0T key.

So, i collected around 10 days of minute by minute simultaneous readings from both sources, the ioreg -rn AppleSmartBattery``Temperature and istats battery temperature, then i ran a linear regression using those values. And given the resulting coefficient and intercept, i have the theory that the ioreg -rn AppleSmartBattery Temperature reading is in tenths of Kelvin. Do you think that is possible?

What bothers me is that while the conversion is very good (.975 Rˆ2 with the tenths of kelvin to celsius conversion) it is not perfect, there are some different ioreg readings with the same istats value. That could be maybe that the sensor changed value before the second measurement was taken, they are technically not simultaneous. Or that they are coming from different sensors. If they come from different sensors, which is the one to trust?

Well, i hope you find this interesting and share your expert insights.

Thank you!

Sparklines don't respect temperature units

First, thanks for this awesome utility!

When I do not use the -f flag, my CPU temperature is normal (say, 44 degrees Celsius). However, when I enable -f, the CPU temperature jumps appropriately (say, to 110 degrees Fahrenheit), and the sparkline flashes red (I'm assuming because the new value is above the threshold designed for Celsius temperatures).

More battery stats

Stats to add:

• Current Max mAH
• Original Max mAH
• Health (current / original)
• Current mAH usage

Tsqf sensor Unknown

MacBook Pro (15-inch, Mid 2012)
El Capitan 10.11.6 (15G1421)

After changing standard hard drive to SSD I'm seeing heating problems (kernel takes over and system performance slows [expected behaviour] - fans shift to high rotation as they should). I've used iStats to see various temperatures. The one sensor value returned by iStats that seems to correlate with slowdowns is: Tsqf Unknown
Moves from normal temp (about 43C) up to 74C when the kernel kicks in to take over.
**I've searched lots but cannot find any references to the Tsqf key. Any ideas what this is? **
Thanks.

--value-only and rounded values

Hey Chris,
I'm working on some cool stuff (will share it soon, spoiler: you can check my empty repo 😜)
Is there a flag to get rounded values or I have to use awk or bc? Thanks!

Feature request

would be nice to have a way to loop the code, without using watch or other methods

Problem installing on 10.9.4

Hi there,
Was very excited to try this out but i encountered an error installing it on my week-old macbook pro, i7 running 10.9.4. I've never used ruby before so I appologize if I'm missing something but I ran sudo gem install iStats and this was the error:

It would be cool if istats could monitor the temp over some time and show me a graph

How can I show these stats on my desktop with Übersicht?

I want to show my temp on my desktop with the tool Übersicht I thought it would be easy to to, but I came to the conclusion I am not that great with the terminal. I thought I could use the ical-widget as a template, but I can't make the iState command executable via the widget.

Any help would be appreciated.
