Indy

Fancy having your own Dr. Henry Walton "Indiana" Jones, Jr? Now you can!

 
var Indy = require('indy');
 
var indy = new Indy();
 
// Defaults to our artefact custom event dispatcher.
// Times eventloop delay, process info, memory info, etc.
indy.whip( { /* dispatcher: new StatsD() */  } );
 
// Not sure why you would need it yet but, lets just see.
indy.pause();
indy.resume();
 
// Dumps a metric shit-ton of things, memory, core, yada yada ya.
// Breaks things, blocks the eventloop etc. not fun.
indy.extract(); // heart!
 
// We always forget this!
indy.hat();
 

The default dispatcher will log the example output using console.log as an example. A statsd version of this is available at tomgco/indy-statsd to use, or to base off of your own metrics sink hole.

var StatsdIndy = require('indy-statsd');
indy.whip({ dispatcher: new StatsdIndy() });
