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.
Syntax
var promise = RTCRtpSender.getStats();
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.
Example
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(function(stats) { document.getElementById("currentRTT").innerText = stats.roundTripTime; });
