NAME

netpeek(3)

SYNOPSIS

Find out how many bytes each module communicates over the network without using c++

USAGE

Netpeek can also take an option { aggregate: true } if you want to add all the bytes together instead of emitting them each time data is collected. Once Netpeek is required, it will start collecting data from anywhere in your application.

var netpeek = require('../../netpeek')();
var assert = require('assert');

require('./test/tests/http-request-aggregate');

netpeek.on('data', function(data) {
  console.log(data);
});

EXAMPLES

Output data is json.

{ 
  "/Users/workroot/git/hij1nx/net-peek/test/tests/http-request-aggregate.js": {
    "httpParseCount": 2,
    "bytesRead": 3423,
    "bytesDispatched": 496
  }
}

The following code (test/tests/http-request-aggregate.js) produced the output above.

var http = require('http');

var options = {
  hostname: 'www.google.com',
  port: 80,
  path: '/upload',
  method: 'POST'
};

var req = http.request(options, function(res) {
  res.setEncoding('utf8');
  res.on('data', function (chunk) {});
});

req.on('error', function(e) {});

req.write('data\n');
req.write('data\n');
req.end();
