{{APIRef("WebRTC")}}
The {{domxref("RTCRtpReceiver")}} method getStats() asynchronously requests an {{domxref("RTCStatsReport")}} object which provides statistics about incoming traffic on the owning {{domxref("RTCPeerConnection")}}, returning a {{jsxref("Promise")}} whose fulfillment handler will be called once the results are available.
getStats()
None.
A JavaScript {{jsxref("Promise")}} which is fulfilled once the statistics are available. The promise's fulfillment handler receives as a parameter a {{domxref("RTCStatsReport")}} object containing the collected statistics.
The returned statistics include those from all streams which are coming in through the RTCRtpReceiver, as well as any of their dependencies.
These might include, for example, statistics with types: inbound-rtp, candidate-pair, local-candidate, remote-candidate.
This simple example obtains the statistics for an RTCRtpReceiver and updates an element's {{domxref("HTMLElement/innerText", "innerText")}} to display the number of packets lost.
receiver.getStats().then((stats) => {
document.getElementById("lost-packets").innerText = stats.packetsLost;
});
