Note

This is fork from https://github.com/tj/node-blocked with the following changes:

• ability for custom interval
• interval defaults to 1s
• call fn when difference > 0

blocked

Check if a node event loop is blocked.

Installation

$ npm install blocked

Example

The blocked() function reports every value over 10ms, do whatever you want with that value, graph it, log it, alert, etc.

The process won't be kept open through this!

var blocked = require('blocked');

setInterval(function(){
  Array(10000000).join('a')
}, 500);

setInterval(function(){
  Array(100000000).join('a')
}, 3000);

blocked(function(ms){
  console.log('BLOCKED FOR %sms', ms | 0);
});
