Server side component for monitoring WebRTC applications and services

Table of Contents:

Qucik Start

Install it from npm package repository.

npm i @observertc/observer-js

Use it in your server side NodeJS app.

import { createObserver, ClientSample } from "@observertc/observer-js";

const observer = createObserver({
    defaultServiceId: 'my-service-name',
    defaultMediaUnitId: 'my-reporting-component',
});

const observedCall = observer.createObservedCall({
    roomId: 'roomId',
    callId: 'room-session-id',
});

const observedClient = observedCall.createObservedClient({
    clientId: 'client-id',
    mediaUnitId: 'media-unit-id',
});

const clientSample: ClientSample; // Receive your samples, for example, from a WebSocket

observedClient.accept(clientSample);

The above example do as follows:

  1. create an observer to evaluate samples from clients and sfus
  2. create a client source object to accept client samples
  3. add an evaluator process to evaluate ended calls

Get a Summary of a call when it ends

const monitor = observer.createCallSummaryMonitor('summary', (summary) => {
    console.log('Call Summary', summary);
});

How Many Clients are using TURN?

const monitor = observer.createTurnUsageMonitor('turn', (turn) => {
    console.log('TURN', turn);
});

// at any point of time you can get the current state of the turn usage

console.log('Currently ', monitor.clients.size, 'clients are using TURN');

// you can get the incoming and outgoing bytes of the TURN server
console.log(`${YOUR_TURN_SERVER_ADDRESS} usage:`, monitor.getUsage(YOUR_TURN_SERVER_ADDRESS));

Monitor Calls and Clients as they updated

observer.on('newcall', (call) => {
    call.on('update', () => {
        console.log('Call Updated', call.callId);
    });

    call.on('newclient', (client) => {

        client.on('update', () => {
            console.log('Client Updated', client.clientId);

            console.log(`The avaialble incoming bitrate for the client ${client.clientId} is: ${client.availableIncomingBitrate}`)
        });
    })
});
