The Systeminformation Project

This is amazing. Started as a small project just for myself, it now has > 15,000 lines of code, > 600 versions published, up to 8 mio downloads per month, > 220 mio downloads overall. #1 NPM ranking for backend packages. Thank you to all who contributed to this project!

Please support this project ... ☕️

Over the past few years I spent more than 2.000 hours working on this project and invested in hardware to be able to test on different platforms. Currently I am working very hard on the next new version 6.0 completely rewritten in TypeScript and with a lot of new features. Any support is highly appreciated - Buy me a coffee.

Your contribution make it possible for me to keep working on this project, add new features and support more platforms. Thank you in advance!

New Version 5.0

The new Version 5 is here - this next major version release 5.0 comes with new functionality and several improvements and changes (some of them are breaking changes!):

• added audio: get detailed audio device information
• added bluetooth: get detailed bluetooth device information
• added dockerImages, dockerVolumes: get detailed information about docker images and volumes
• added printer: get information from detected printers
• added usb: get detailed usb controller and device information
• added wifi interfaces and connections: extended wifi information
• better uuid function to get unique hardware and OS UUIDs
• better/extended cpu info detection
• better/extended system info detection
• Apple Silicon M1/M2/M3 support
• better Raspberry-PI detection
• systeminformation website updated and extended with full documentation and examples systeminformation.io
• lot of minor improvements

Breaking Changes in version 5: you will see several breaking changes for the sake of a more consistent API interface and to be future proof. Read the detailed version 5 changes.

I did a lot of testing on different platforms and machines but of course there might be some issues that I am not aware of. I would be happy if you inform me when you discover any issues. Issues can be opened here.

Quick Start

Lightweight collection of 50+ functions to retrieve detailed hardware, system and OS information.

• simple to use
• get detailed information about system, cpu, baseboard, battery, memory, disks/filesystem, network, docker, software, services and processes
• supports Linux, macOS, partial Windows, FreeBSD, OpenBSD, NetBSD, SunOS and Android support
• no npm dependencies

Attention: this is a node.js library. It is supposed to be used as a backend/server-side library and will definitely not work within a browser.

Installation

npm install systeminformation --save

or simpler

npm i systeminformation

Give it a try with npx?

You just want to give it a try - right from your command line without installing it? Here is how you can call it with npx:

# get basic system info (System, OS, CPU)
npx systeminformation info

# obtain all static data - may take up to 30 seconds
npx systeminformation

Still need Version 4?

If you need version 4 (for compatibility reasons), you can install version 4 (latest release) like this

npm install systeminformation@4 —save

or simpler

npm install systeminformation@4

Usage

All functions (except version and time) are implemented as asynchronous functions. Here a small example how to use them:

const si = require('systeminformation');

// promises style - new since version 3
si.cpu()
  .then(data => console.log(data))
  .catch(error => console.error(error));

Core concept

Node.js comes with some basic OS information, but I always wanted a little more. So I came up to write this little library. This library is still a work in progress. It is supposed to be used as a backend/server-side library (it will definitely not work within a browser). It requires node.js version 4.0 and above.

I was able to test it on several Debian, Raspbian, Ubuntu distributions as well as macOS (Mavericks, Yosemite, El Captain, Sierra, High Sierra, Mojave, Catalina, Big Sur) and some Windows 7, Windows 8, Windows 10, FreeBSD, OpenBSD, NetBSD and SunOS machines. Not all functions are supported on all operating systems. Have a look at the function reference in the docs to get further details.

If you have comments, suggestions & reports, please feel free to contact me!

I also created a nice little command line tool called mmon (micro-monitor) for Linux and macOS, also available via github and npm

cb: Asynchronous Function Calls (callback)

Remember: all functions (except version and time) are implemented as asynchronous functions! There are now three ways to consume them:

Callback Style

const si = require('systeminformation');

si.cpu(function(data) {
  console.log('CPU Information:');
  console.log('- manufacturer: ' + data.manufacturer);
  console.log('- brand: ' + data.brand);
  console.log('- speed: ' + data.speed);
  console.log('- cores: ' + data.cores);
  console.log('- physical cores: ' + data.physicalCores);
  console.log('...');
})

Promises

Promises Style is new in version 3.0.

When omitting callback parameter (cb), then you can use all function in a promise oriented way. All functions (except of version and time) are returning a promise, that you can consume:

const si = require('systeminformation');

si.cpu()
  .then(data => {
    console.log('CPU Information:');
    console.log('- manufacturer: ' + data.manufacturer);
    console.log('- brand: ' + data.brand);
    console.log('- speed: ' + data.speed);
    console.log('- cores: ' + data.cores);
    console.log('- physical cores: ' + data.physicalCores);
    console.log('...');
  })
  .catch(error => console.error(error));

Async / Await

Using async / await (available since node v7.6)

Since node v7.6 you can also use the async / await pattern. The above example would then look like this:

const si = require('systeminformation');

async function cpuData() {
  try {
    const data = await si.cpu();
    console.log('CPU Information:');
    console.log('- manufacturer: ' + data.manufacturer);
    console.log('- brand: ' + data.brand);
    console.log('- speed: ' + data.speed);
    console.log('- cores: ' + data.cores);
    console.log('- physical cores: ' + data.physicalCores);
    console.log('...');
  } catch (e) {
    console.log(e)
  }
}

Known Issues

macOS - Temperature Sensor

To be able to measure temperature on macOS I created a little additional package. Due to some difficulties in NPM with optionalDependencies I unfortunately was getting unexpected warnings on other platforms. So I decided to drop this optional dependency for macOS - so by default, you will not get correct values.

This additional package is now also supporting Apple Silicon M1/M2/M3 machines.

But if you need to detect macOS temperature just run the following additional installation command:

$ npm install osx-temperature-sensor --save

systeminformation will then detect this additional library and return the temperature when calling systeminformations standard function cpuTemperature()

Windows Temperature, Battery, ...

get-WmiObject - which is used to determine temperature and battery sometimes needs to be run with admin privileges. So if you do not get any values, try to run it again with according privileges. If you still do not get any values, your system might not support this feature. In some cases we also discovered that get-WmiObject returned incorrect temperature values.

Linux Temperature

In some cases you need to install the Linux sensors package to be able to measure temperature e.g. on DEBIAN based systems by running sudo apt-get install lm-sensors

Linux S.M.A.R.T. Status

To be able to detect S.M.A.R.T. status on Linux you need to install smartmontools. On DEBIAN based Linux distributions you can install it by running sudo apt-get install smartmontools

Windows Encoding Issues

I now reimplemented all windows functions to avoid encoding problems (special chacarters). And as Windows 11 now dropped wmic support, I had to move completely to powershell. Be sure that powershell version 5+ is installed on your machine. On older Windows versions (7, 8) you might still see encoding problems due to the old powershell version.

*: Additional Notes

In fsStats(), disksIO() and networkStats() the results / sec. values (rx_sec, IOPS, ...) are calculated correctly beginning with the second call of the function. It is determined by calculating the difference of transferred bytes / IOs divided by the time between two calls of the function.

The first time you are calling one of these functions, you will get null for transfer rates. The second time, you should then get statistics based on the time between the two calls ...

So basically, if you e.g. need a value for network stats every second, your code should look like this:

const si = require('systeminformation');

setInterval(function() {
  si.networkStats().then(data => {
    console.log(data);
  })
}, 1000)

Beginning with the second call, you get network transfer values per second.

systeminformation's Issues

cpu_percent from si.dockerContainerStats is inconsistent with the output of "docker stats"

Hi,

I'm using si.dockerContainerStats to get the cpu usage of the container. The strange thing is that the output is nearly ten times the output of docker cli 'docker stats'.

For example, while the output of docker stats is 90%, the output of si is nearly 900.

Not sure what happens?

use of new si.blockDevices(cb)

Hello again, Sebastian,

I can't get this to work. I tested in the Node.js REPL (see below).

This is a CentOS 6 VM.

Am I doing something wrong?

In the meantime, I will try it on an Ubuntu 16 VM.

Thanks.

cpuTemperature not returning anything on OSX or Windows

Hi Sebastian,

First off thanks for putting this package together, I have enjoyed working with it the last couple of days.

Unfortunately, I have noticed that cpuTemperature is not returning anything. I have tested on OSX and Windows 10 and have confirmed with other system apps that both devices have a temp monitor running and reporting.

Cheers,

Not all ifaces detected, users problem

So i just tried new version of systeminformation.

It doesn't crash without root - that's great. But few things don't look entirely correct:

networkStats:

sys.networkInterfaces(function(s){console.log(s)})
Promise { <pending> }
> [ { iface: 'lo', ip4: '127.0.0.1', ip6: '::1', internal: true },
{ iface: 'br0',
ip4: '192.168.1.3',
ip6: 'fe80::f66d:4ff:fe97:cc1c',
internal: false },
{ iface: 'vmnet1',
ip4: '172.16.56.1',
ip6: 'fe80::250:56ff:fec0:1',
internal: false },
{ iface: 'vmnet8',
ip4: '192.168.99.1',
ip6: 'fe80::250:56ff:fec0:8',
internal: false } ]

whereas:

lapsio@linux-qzuq ~> ip link list
1: lo: ...
2: eno1: ... <- missing
3: br0: ...
4: vmnet1:...
5: vmnet8: ...

I just checked and os.networkInterfaces is also missing eno1

And .users() returns empty array now on my machine.

Here's result of command you use, I hope it helps:
http://pastebin.com/YW41Dpma

I found it quite confusing that .services without srv argument return nothing instead of all and those "-1"s in many places also look confusing. I followed code and considering _disk_io.ms doesn't seem to be set anywhere they're like hardcoded?

CPU temp

I was looking around for some monitoring packages for node and found your one. While reading about how to use it saw that you had an issue getting the CPU temperature. Just a quick search and found another package that uses the SMC from Apple.
Hope this solves your "problem" :)
https://github.com/mmarcon/node-smc
https://github.com/jkuri/macstats

Permissions

It'd be really nice to have some flag indicating level of privilleges, especially for getAllData or maybe even autodetect because currently lib is crashing with EACCES on my os if not run as root.

Error: EACCES: permission denied, open '/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq'

si.cpuTemperatue is not a function

Does this mean that it's not supported by the cpu/os?

The error:

(node:9740) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 3): TypeError: si.cpuTemperatue is not a function

My code:

    private getTemperature(): Promise<number> {
        return new Promise<number>((resolve, reject) => {
            si.cpuTemperatue(resolve);
        });
    }

CPU Usage in %

Hello,
I liked your project.
But I'm kind of dumb and I do not know how to make my code look just like you.
Could you please review and include my code in your next version?
Thank you

                });
                resolve(lines);
            };

Is there a plan to support `si.networkStats()` on Windows ?

I have tried to use si.networkStats('Wi-Fi') on Windows.

It seems the operation is not yet supported on Windows, I got Error: not supported.

Kindly ask, any plan and when will you support it ?

si.mem(cb) - Memory information - Not resolve promise on windows

Hi Sebastian Hildebrandt,

Congratulations but this work, is really good : )

However i found a issue on "si.mem(cb)" function because "Windows_NT" platform not resolve the promise, because of this never return of information.

It would be great to finish this.

Thanks Sebastian.

A greetings.

Problem at linux with other locales than english

Hi,

Your work is great, only have one problem at some of my clients, they have a german locale at console. So there is only one problem at filesystem.js line #594 where you execute lshw to get disks. You are looking for the key "logical name" but i get at the clients "Logischer Name" cause of german locale. So i can't force them all to set console locale to english as default. Sure i can tell all they must have installed english as secondary locale.

The only real problem is that i get an error 'cat /sys/block/' + logical + '/queue/rotational' cause logical is empty at my case and so the dir it tries to cat does not exist.

At least i need a fix for checking if the dir exists before cat'ing it (think those two lines are not to hard to you so i don't have to send a pull request ;) )

But much better would be a solution to get the devices at systems with other default locale than english too. I'm 100% sure at the moment how to solve this, but maybe you have an idea :)

not sure if it's possible to maybe forcing the console output to english (like i said, i can install a second locale), but maybe you/we find a solution where it's not important which locale is installed (maybe catching it not by key, catching it by something like substring with /dev/?... just one more idea ;) )

greetings
Chris

Units for the different properties

I'd like to know what unit si.mem.total uses, and maybe add it to the readme.

I thought it was bytes, but when I used si.mem, I got

8494383104
Which in GB is 8.49~
While Windows tells me that I have 8.00

Thanks in advance.

Enhancement request

Hi Sebastian,

When you are able to address issue #21 might you be able to make a modest (I think) enhancement to the list of process properties returned by si.processes(cb)?

Specifically, could that list include for each returned process object not only pcpu, but its decomposition into system (kernel) CPU utilization and user CPU utilization?

Not that you need it, but vide: http://unix.stackexchange.com/questions/132035/obtain-user-and-kernel-time-of-a-running-process

Thanks.

Not reliable `getFirstExternalNetworkInterface` function

Hi, I'm reading the code of your library and I think you are using the getFirstExternalNetworkInterface function to get the current active interface in the system to start monitoring the data transfer speed.

If I'm correct about this, there's a problem with that function and is not reliable.

Note: I'm using OS X

If I have my WiFi connection active and I'm also connected to wired using the thunderbolt port the os.networkInterfaces() execution will return this:

    }
  ],
  utun1: [

      mac: '00:00:00:00:00:00',
      scopeid: 11,
      internal: false
    }
  ],
  en5: [
    {
      address: 'fe80::ca2a:14ff:fe4c:1543',
      netmask: 'ffff:ffff:ffff:ffff::',
      family: 'IPv6',
      mac: 'c8:2a:14:4c:15:43',

    {
      address: '10.225.128.233',
      netmask: '255.255.0.0',
      family: 'IPv4',
      mac: 'c8:2a:14:4c:15:43',
      internal: false
    }
  ]
}

With this data, the getFirstExternalNetworkInterface will return en0 as the active interface which is correct, but if I turn off my WiFi device and and execute the os.networkInterfaces() method again the output will be this:

{
  lo0: [
    { 
      address: '::1',
      netmask: 'ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff',
      family: 'IPv6',
      mac: '00:00:00:00:00:00',
      scopeid: 0,
      internal: true
    },
    {
      address: '127.0.0.1',
      netmask: '255.0.0.0',
      family: 'IPv4',
      mac: '00:00:00:00:00:00',
      internal: true
    },
    {
      address: 'fe80::1',
      netmask: 'ffff:ffff:ffff:ffff::',
      family: 'IPv6',
      mac: '00:00:00:00:00:00',
      scopeid: 1,
      internal: true
    }
  ],
  utun1: [
    {
      address: 'fe80::d006:2732:5299:2715',
      netmask: 'ffff:ffff:ffff:ffff::',
      family: 'IPv6',
      mac: '00:00:00:00:00:00',
      scopeid: 11,
      internal: false
    }
  ],
  en5: [
    {
      address: 'fe80::ca2a:14ff:fe4c:1543',
      netmask: 'ffff:ffff:ffff:ffff::',
      family: 'IPv6',
      mac: 'c8:2a:14:4c:15:43',
      scopeid: 12,
      internal: false
    },
    {
      address: '10.225.128.233',
      netmask: '255.255.0.0',
      family: 'IPv4',
      mac: 'c8:2a:14:4c:15:43',
      internal: false
    }
  ]
}

And the getFirstExternalNetworkInterface will return utun1 as the active interface which is incorrect, since the current active interface is en5.

I see two problems here...

• You are relaying in the internal === false value to determine which is the active interface
• You are trying to get the first value of an object which is a non-ordered structure

typescript definitions

The best option is to maintain this with the library instead of having a @types package IMO.
We can provide a d.ts or convert the project to typescript, I prefer the last option but I can contribute to the first one too.

UnhandledPromiseRejectionWarning

Hi! Great package, really appreciate your work!

It works without problems on my PC and even Raspberry PI 2 :) , but I have problem while running this simple test program on my laptop:

var si = require('systeminformation');

si.getStaticData(function (data) {

});

In the console instead of static informations about by laptop I get this:

Any idea what may cause this error? My laptop is Samsung QX310, running on Windows 10 Pro (same version as on my PC), maybe it's something about my laptops hardware? :|

Missing Validation in osInfo (Windows)

I was trying your lib (btw, nice job) and in the osInfo function you missed a validation for Windows logo that throws:

C:\Users\Fxckdead\Desktop\testing\node_modules\systeminformation\lib\osinfo.js:43
  distro = distro.toLowerCase();
                 ^

TypeError: Cannot read property 'toLowerCase' of undefined
    at getLogoFile (C:\Users\Fxckdead\Desktop\testing\node_modules\systeminformation\lib\osinfo.js:43:18)

In that line i can see:

// Get logo filename of OS distribution

function getLogoFile(distro) {
  distro = distro.toLowerCase(); // <-- THIS LINE 

For the windows version you don't send the distro param, so toLowerCase is not an string:

197    if (_windows) {
198        result.logofile = getLogoFile();

I can't send a pull request right now, but its an easy fix.

SocketIO

Hi,
First of all congratulations for this amazing project.
I have two questions:
1ºDo you have any example using socket io for real-time monitor?
2ºUsing si.processes(cb) how can I get only the running proccess?

Best regards

si.diskLayout on CentOS 7 (systemd-based)

Hi Sebastian,

Using 3.17.2 on CentOS 7 si.diskLayout(cb) returns an empty (pending) promise which is never fulfilled, e.g.,

[root@localhost ecxmon]# node
> var si = require('systeminformation')
undefined
> si.diskLayout(function(d) {console.log(d)})
Promise { <pending> }
> []

FWIW si.memLayout() works. I haven't tried on a non-systemd platform.

Thanks.

question about list returned by si.processes()

Hi Sebastian,

Happy New Year & hope you are well.

The process object returned under si.processes().list contains a 'pcpu' (percent CPU utilization) field. How should I interpret this number on a multi-core machine?

I here have in mind the difference between the top command's Irix (the default, I think) and Solaris modes. In the former, %CPU is not divided by the number of cores; in the latter it is.

As always, thanks for your help.

Cordially,

Paul

SWAP is NaN

Because free in version 3.3.10 doesn't display -/+ buffers/cache any more, there's only two columns and line 3 (for swap) just doesn't exist.

A simple fix could be to count number of lines and act consequently…

Temperature Returns Innacurate Data

Using cputemperature to measure the temperature of my CPU, I get these values:

{ main: -172.86666666666667, cores: [ -273.2, -273.2, 27.8 ], max: -1 }

My CPU only has two cores but it is indicated that there are three.

Also, I haven't checked using any other software, but I'm fairly sure my CPU isn't at Absolute Zero.

Is this an issue with the sensors on my CPU?

How to use import systeminformation on react.js project

Hi,
I can't import this syteminformation.js on my react.js project. I worked this on Mac OS 10.11.6.
After run 'npm install systeminformation --save" command, I added a line in my line:
import si from 'systeminformation';

Then I got issue:
ERROR in ./ ~ /systeminformation/lib/cpu.js
Module not found: Error: Cannot resolve 'file' or 'directory' ../build/Release/smc in /Users/pascal/Sites/key/keytabs/node_modules/systeminformation/lib
@ ./ ~ /systeminformation/lib/cpu.js 251:18-49

Please help me how to fix this issue.

Race condition?

Hi Sebastian,

This issue appears to be similar to #14 which you fixed for us last November.

But in this case it is si.processes() - and not si.currentLoad() - that may prove problematic. I say "may" because I am always willing to allow that this problem is of my making.

My web browser client is presenting 2 d3.js plots simultaneously. In the Node.js backend this is realized as two "overlapped" (roughly concurrent) calls to si.processes(). I will paste in the code below.

If I display the process CPU utilization plot by itself, data values returned by si.processes() seem fine. But if I display both process CPU utilization & the process memory utilization plots at the same time, then the data returned by si.processes() assumes quite a few incorrect values. E.g., "Infinity", "NaN", and negative CPU utilizations.

In the code below, the 2 "collector" functions, one for CPU utilization, the other for memory, run "concurrently" (well, not really, but in the Node.js idiom). Each calls si.processes() and then calls function getProcessesOfInterest .

Thanks for your help.

Cordially,

Paul

CentOS 7 problems

Hi,

First, thank you very much for this fine piece of work! It's been a great help to me.

I was today experimenting with the several docker APIs offered by your module and it seems that two of them don't work in CentOS 7. I presume that this is perhaps more a systemd issue than anything else.

In response to, for example, si.dockerContainers('all', function(d) { console.log(d); }) I see:

Promise { <pending> }
> []

I get the same empty promise array in response to .dockerAll(cb). But .dockerContainerStats(ctrID, cb) seems to work fine.

All API calls work properly on CentOS 6 (and on Ubuntu 16.04).

Do these phenomena comport with your experience? If this is a valid new issue, is it something that can be fixed without too much work?

Thank you again.

Cordially,

Paul

Behavior of si.fsSize() ?

Hi Sebastian,

It seems to me that fsSize reports accurately only the first disk if finds, e.g., /dev/sda. In the output below I see partitions /dev/sda1 and /dev/sda3, but not /dev/sda2. I also don't see /dev/sda (the disk itself as opposed to its partitions.) Nor is the /dev/mapper data correct. Finally, devices /dev/sdb and /dev/sdc do not appear at all.

Am I missing something in my use of fsSize? If not, is this something that you can, without too much difficulty, enhance to include all disks and partitions?

As always, thank you.

-Paul

"mem is not a function" using si.getAllData()

si.currentLoad race conditions?

Hi Sebastian,

Before I start posting massive debug log output, are you aware of any potential race issues with this (or any other) si call?

The basic conditions & sequence are as follows:

1. backend https server (Node.js, express.js) periodically (every 5 seconds) drive si.currentLoad using promise idiom (see below).
2. client 1 web browser connects
3. data pushed back to client 1 looks correct
4. client 2 web browser connects
5. data pushed back to client 2 looks incorrect

si.currentLoad().then(data => parseCpuLoadInfo('cpu_util', data, cmdProgress, responder))      
                         .catch(error => logMsg('info', 'si.currentLoad error=' + error));

When item 4 above says "incorrect", I mean that the several metrics returned by this call (currentload, currentload_system, currentload_user, currentload_nice) are either null or incoherent, e.g., the client 1 data shows currentload of 1.004 but 5 seconds later currentload for client 2 shows 100. Note that there is nothing else running on the node. It might of some interest to note that the avgload property never shows a null or incoherent value, even if the other properties in the object do.

I realize that this could very well be my problem but, for the moment I don't see what I'm doing that might be causing this.

So I'd be grateful for any light you can shed on this.

Thanks.

networkStats rx_sec, tx_sec always at -1 & fsStats rx_sec, wx_sec always at 0

Hey, thanks for your great module!

I tried on two different Ubuntu 16.04 machines, with both node 4.4.5 and 6.2.1.
The realtime metrics for networkStats and fsStats don't seem to work.

Exemple output:

…
networkStats: 
 { iface: 'eth0',
   operstate: 'unknown',
   rx: 0,
   tx: 0,
   rx_sec: -1,
   tx_sec: -1 },
…
fsStats: { rx: 455069696, wx: 4253657088, rx_sec: 0, wx_sec: 0 },
…

Change in content of si.processes?

Hi Sebastian,

It looks to me that the list array within the data returned by si.processes() no longer contains a proper command property. In fact, it looks to me as if the command property might contain the userid under which the process is running.

I'm fairly certain that I used to use the command property to help me identify processes of interest, e.g., various startup flags, etc.

I am using 3.17.0 version of si.

Can you confirm my findings?

Thanks.
