Performance: resourcetimingbufferfull event

The resourcetimingbufferfull event is fired when the browser's resource timing buffer is full.


Use the event name in methods like addEventListener(), or set an event handler property.

addEventListener('resourcetimingbufferfull', (event) => { });

onresourcetimingbufferfull = (event) => { };

Event type

A generic Event.


The following example sets a callback function on the onresourcetimingbufferfull property.

function buffer_full(event) {
  console.log("WARNING: Resource Timing Buffer is FULL!");
function init() {
  // Set a callback if the resource buffer becomes filled
  performance.onresourcetimingbufferfull = buffer_full;
<body onload="init()">

Note that you could also set up the handler using the addEventListener() function:

performance.addEventListener('resourcetimingbufferfull', buffer_full);
