    Build Status Coverage Status Dependency Status npm version npm Downloads

    Node.js library to get a snapshot of the currently running processes, OS-agnostic. Needs root/Admin permissions.

    Usage example

    var _ = require('lodash');
    var ps = require('current-processes');
     
    ps.get(function(err, processes) {
     
        var sorted = _.sortBy(processes, 'cpu');
        var top5  = sorted.reverse().splice(0, 5);
     
        console.log(top5);
    });

    Process object

    The library will return an array consisting of multiple process objects, structured like this:

    {
        pid: 1337,               // Process ID
        name: 'chrome',          // Process name
        mem: {
            private: 23054560,   // Private memory, in bytes
            virtual: 78923608,   // Virtual memory (private + shared libraries + swap space), in bytes
            usage: 0.02          // Used physical memory (%) by this process
        },
        cpu: 0.3                 // CPU usage (%) as reported by `ps` and `wmic`
    }

    Platform-specific notes

    Windows

    WMI (specifically wmic) is used to gather the information itself. WMI is fairly slow the first time it's called, it might even take up to 2-3 seconds. Make sure your app will gracefully handle this. Subsequent calls will be much faster.
