RTCDataChannelStats

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The RTCDataChannelStats dictionary of the WebRTC API provides statistics related to one RTCDataChannel object on the connection.

The report can be obtained by iterating the RTCStatsReport returned by RTCPeerConnection.getStats() until you find an entry with the type of data-channel.

The data channels statistics may be correlated to a particular channel by comparing the dataChannelIdentifier property to a matching RTCDataChannel.id.

Instance properties

bytesSent Optional

A positive integer value indicating the total number of payload bytes sent on the associated RTCDataChannel.

bytesReceived Optional

A positive integer value indicating the total number of payload bytes received on the associated RTCDataChannel.

dataChannelIdentifier Optional

A positive integer value containing the id of the associated RTCDataChannel.

label Optional

A string containing the label of the associated RTCDataChannel.

messagesReceived Optional

A positive integer value indicating the total number of message events fired for received messages on the associated RTCDataChannel.

messagesSent Optional

A positive integer value indicating the total number of message events fired for sent messages on the channel.

protocol Optional

A string containing the protocol of the associated RTCDataChannel.

state

The readyState of the associated RTCDataChannel.

Common instance properties

The following properties are common to all WebRTC statistics objects (See RTCStatsReport for more information).

id

A string that uniquely identifies the object that is being monitored to produce this set of statistics.

timestamp

A DOMHighResTimeStamp object indicating the time at which the sample was taken for this statistics object.

type

A string with the value "data-channel", indicating the type of statistics that the object contains.

Examples

Given a variable myPeerConnection, which is an instance of RTCPeerConnection, the code below uses await to wait for the statistics report, and then iterates it using RTCStatsReport.forEach(). It then filters the dictionaries for just those reports that have the type of data-channel and logs the result.

js
const stats = await myPeerConnection.getStats();

stats.forEach((report) => {
  if (report.type === "data-channel") {
    // Log the channel information
    console.log(report);
  }
});
