eventloop-info

Detects and measures the latency of the NodeJS event loop

api

eventLoopInfo(function(err, delay, addInfo), [threshold])

• fn callback

  • err, error object, currently we aren't handle or passing errors just follwing the NodeJS standards
  • delay integer, returns the event loop delay in ms
  • addInfo js object, returns an object with memory and cpu usage at the time of the blocking/delay op

• threshold integer, used to set up the amount of ms to execute the fn callback, default to 10 ms

example

const eventLoopInfo = require('eventloop-info')
 
//
 
eventLoopInfo((err, delay, addInfo) => {
    // delay in ms
    // addInfo an js object with memory and cpu usage
})
