proc-stats

proc-stats

library for getting memory and cpu usage for windows, mac or linux - other os's are not supported. No production dependancies or compilation needed :)

look at the unit tests to see how it is used. remember - you can pull out basic process memory stuff (rss, heapTotal, heapUsed) using process.memoryUsage() - this gives you the % CPU usage per process, and if you are using linux the vsize

usage:

npm install proc-stats

 
var procStats = require('proc-stats');
 
procStats.stats(function(e, result){
    /*
      linux:
      result looks like:
      { 
      	memory: 25751552, // resident set size
      	memoryInfo: 
      		{ rss: 25751552, // resident set size
      		  vsize: 3123171328,//virtual set size
      		  heapTotal: 16486912, 
  			  heapUsed: 9636688 
  			}, 
      	cpu: 1.6 
      } //CPU USAGE
 
      windows:
      result looks same, but no vsize 
      { 
      	memory: 25751552, // resident set size
      	memoryInfo: 
      		{ rss: 25751552, // resident set size
      		  heapTotal: 16486912, 
  			  heapUsed: 9636688 
  			}, 
      	cpu: 1.6 
      } //CPU USAGE
    */
});
 

thanks to Kyll Ross for the windows stuff, https://github.com/KyleRoss/windows-cpu - NB though, I have been testing, and the CPU time always seems to be returningzero - I suspect my unit test isnt generating enough load on windows, dont have time right now to investigate further...
