找出脚本使用了多少内存

Question

in PHP I can use memory_get_usage() .

Is there anything like that in nodejs? The memwatch library doesn't seem to provide that info, it only emits some events when a "leak" occurs

Answer 1

Have you read this article https://hacks.mozilla.org/2012/11/tracking-down-memory-leaks-in-node-js-a-node-js-holiday-season/ ? There are some nice examples.

What about memwatch's stats event ?

var memwatch = require('memwatch');
memwatch.on('stats', function(stats) {
// do something with post-gc memory usage stats
});

Answer 2

Get concerned object describing the memory usage of the Node process.

var util = require('util');

console.log(util.inspect(process.memoryUsage()));

result:

{ rss: 4935680,
  vsize: 41893888,
  heapTotal: 1826816,
  heapUsed: 650472 }

heapTotal and heapUsed refer to V8's memory usage.
