paw-info v3.18.1

systeminformation

Simple system and OS information library for node.js

Quick Start

Collection of 30+ functions to retrieve detailed hardware, system and OS information (Linux, OSX and now partial Windows support)

Installation

$ npm install systeminformation --save

Usage

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

var si = require('systeminformation');

// callback style
si.cpu(function(data) {
	console.log('CPU-Information:');
	console.log(data);
})

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

News and Changes

Latest Activity

• Version 3.17.0: windows support for some very first functions (work in progress)
• Version 3.16.0: blockDevices: added removable attribute
• Version 3.15.0: added cpuTemperature also for OSX
• Version 3.14.0: added currentLoad per cpu/core, cpu cache (L1, L2, L3) and cpu flags
• Version 3.13.0: added shell (returns standard shell)
• Version 3.12.0: refactoring and extended currentLoad (better OSX coverage and added irq load).
• Version 3.11.0: blockDevices now also for OSX and also extended (+ label, model, serial, protocol).
• Version 3.10.0: added blockDevices (list of disks, partitions, raids and roms).
• Version 3.9.0: extended networkInterfaces (added MAC address).
• Version 3.8.0: added dockerContainerProcesses (array of processes inside a docker container).
• Version 3.7.0: extended dockerContainerStats.
• Version 3.6.0: added versions (kernel, ssl, node, npm, pm2, ...).
• Version 3.5.0: added graphics info (controller and display).
• Version 3.4.0: rewritten currentLoad and CPU load for processes (linux). This is now much more accurate.
• Version 3.3.0: added processes.list. Get full process list including details like cpu and mem usage, status, command, ...
• Version 3.2.0: added battery support. If a battery is installed, you get information about status and current capacity level
• Version 3.1.0: added Docker support. Now you can scan your docker containers and get their stats
• Version 3.0.0: added disksIO - overall diskIO and IOPS values for all mounted volumes

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 work in progress. Version 3 comes with further improvements. First it requires now node.js version 4.0 and above. Another big change is, that all functions now return promises. You can use them like before with callbacks OR with promises (see example in this documentation). I am sure, there is for sure room for improvement. I was only able to test it on several Debian, Raspbian, Ubuntu distributions as well as OS X (Mavericks, Yosemite, El Captain). Since version 2 nearly all functionality is available on OS X/Darwin platforms. Be careful, this library has only very limited Windows support!

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

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

Reference

Sections

This library is splitted in several sections:

1. General
2. System (HW)
3. Operating System
4. CPU
5. Memory
6. File System
7. Network
8. Processes
9. Users
10. Internet
11. Docker
12. GetAll

Function Reference and OS Support

cb: Asynchronous Function Calls (callback)

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

Callback Style

var si = require('systeminformation');

si.networkStats('eth1', function(data) {
	console.log('Network Interface Stats (eth1):');
	console.log('- is up: ' + data.operstate);
	console.log('- RX bytes overall: ' + data.rx);
	console.log('- TX bytes overall: ' + data.tx);
	console.log('- RX bytes/sec: ' + data.rx_sec);
	console.log('- TX bytes/sec: ' + data.tx_sec);
})

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 (exept of version and time) are returning a promis, that you can consume:

si.networkStats('eth1')
	.then(data => {
		console.log('Network Interface Stats (eth1):');
		console.log('- is up: ' + data.operstate);
		console.log('- RX bytes overall: ' + data.rx);
		console.log('- TX bytes overall: ' + data.tx);
		console.log('- RX bytes/sec: ' + data.rx_sec);
		console.log('- TX bytes/sec: ' + data.tx_sec);
	})
	.catch(error => console.error(error));

*: Additional Notes

In fsStats, disksIO and networkStats the results per second values (rx_sec, IOPS, ...) are calculated 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.

Known Issues

I am happy to discuss any comments and suggestions. Please feel free to contact me if you see any possibility of improvement!
