A port of the pyhton library psutil

node-psutil

The start of a port of the pyhton library psutil.

Usage

var PSUtil = require('psutil').PSUtil;

var psUtil = new PSUtil();
psUtil.cpu_times(false, function(err, result) {
  test.equal(null, err);
  test.equal('number', typeof result.user);

  psUtil.cpu_times(true, function(err, result) {
    test.equal(null, err);
    test.equal('number', typeof result[0].user);
    test.done();
  });
});

not really an issue, this module is great for node apps, but do you have plans of adding process methods like python psutils does? for example getting CPU and memory usage for a single process?

multi-cpu reports

You have a small typo in /lib/psutil.js, _cpu_times_linux function.

would have made it a pull request, but... you know how it goes.

great library btw,
using it in my project https://github.com/Zolmeister/ZMonitor
