RTCRtpSender: getStats() method

The RTCRtpSender method getStats() asynchronously requests an RTCStatsReport object which provides statistics about outgoing traffic on the RTCPeerConnection which owns the sender, returning a Promise which is fulfilled when the results are available.





Return value

A JavaScript Promise which is fulfilled once the statistics are available. The promise's fulfillment handler receives as a parameter a RTCStatsReport object containing the collected statistics.

The returned RTCStatsReport accumulates the statistics for all of the streams being sent using the RTCRtpSender, as well as the statistics for any dependencies those streams have.


This simple example obtains the statistics for an RTCRtpSender and updates an element's innerText to display the current round trip time for requests on the sender.

sender.getStats().then((stats) => {
  document.getElementById("currentRTT").innerText = stats.roundTripTime;
