Profiler: samplebufferfull event

{{APIRef("JS Self-Profiling API")}}

The samplebufferfull event of the {{domxref("Profiler")}} interface is fired when the number of samples the profiler has recorded matches the maxBufferSize value passed to the profiler's constructor.

After this event fires, the profiler will not record any more samples.

This event is not cancelable and does not bubble.

addEventListener("samplebufferfull", (event) => { })

onsamplebufferfull = (event) => { }

Event type

An {{domxref("Event")}}.

Examples

const profiler = new Profiler({ sampleInterval: 10, maxBufferSize: 100 });

profiler.addEventListener("samplebufferfull", async () => {
  console.log("Sample buffer full!");
  const trace = await profiler.stop();
  console.log(JSON.stringify(trace));
});
