Azure Communication Services communication monitoring


Functionality described on this section is currently in private preview. Private preview includes access to SDKs and documentation for testing purposes that are not yet available publicly. Apply to become an early adopter by filling out the form for preview access to Azure Communication Services.

The Azure Communication Services communication monitoring tool enables developers to inspect the state of the Call to debug or monitor their solution. For developers building an Azure Communication Services solution, they might need visibility for debugging into general call information such as the Call ID or advanced states, such as did a user facing diagnostic fire. The communication monitoring tool provides developers this information and more. It can be easily added to any JavaScript (Web) solution by downloading the npm package @azure/communication-monitoring.


Find the open-source repository for the tool here.


The Communication Monitoring tool provides developers three categories of information that can be used for debugging purposes:

Category Descriptions
General Call Information Includes call id, participants, devices and user agent information (browser, version, etc.)
Media Quality Stats Metrics and statistics provided by Media Quality APIs. Metrics are clickable for time series view.
User Facing Diagnostics List of user facing diagnostics.

Data collected by the tool is only kept locally and temporarily. It can be downloaded from within the interface.

Communication Monitoring is compatible with the same browsers as the Calling SDK here.

Get started with Communication Monitoring

The tool can be accessed through an npm package @azure/communication-monitoring. The package contains the CommunicationMonitoring object that can be attached to a Call. Instructions on how to initialize the required CallClient and CallAgent objects can be found here. CommunicationMonitoring also requires an HTMLDivElement as part of its constructor on which it will be rendered. The HTMLDivElement will dictate the size of the rendered panel.

Installing Communication Monitoring

npm i  @azure/communication-monitoring

Initialize Communication Monitoring

import { CallAgent, CallClient } from '@azure/communication-calling'
import { CommunicationMonitoring } from '@azure/communication-monitoring'

const selectedDiv = document.getElementById('selectedDiv')

const options = {
  divElement = selectedDiv,

const communicationMonitoring = new CommunicationMonitoring(options)


start: enable the CommunicationMonitoring instance to start reading data from the call object and storing it locally for visualization.


stop: disable the CommunicationMonitoring instance from reading data from the call object.


open: Open the CommunicationMonitoring instance in the UI.

close: Dismiss the CommunicationMonitoring instance in the UI.


Download logs

The tool includes the ability to download the logs captured using the Download logs button on the top right. The tool will generate a compressed log file that can be provided to our customer support team for debugging.
