During a meeting you can view a variety of diagnostic information about the meeting through meeting statistics. By doing this, you will be able to determine if there is a problem with the network, the audio system, or the video system during the meeting.

In addition to viewing diagnostic information, Zoom Phone license holders can view it during a phone call.

You can view diagnostic information during meetings using the VDI Client if you have it.

  • MacOS: 5.8.6 or higher
• Zoom Phone license
• Licensed user to use the audio plan subscription numbers
• Business, Education, or Enterprise plan to purchase Pay-As-You-Go Audio

2. Join or start a meeting.
3. For Start Video / Stop Video, click the upward arrow in the meeting controls.
4. Select Video Settings.
5. Select Statistics.

Access statistics from the main desktop client window

1. Join the Zoom desktop client by logging in with your existing Zoom account.
2. You can adjust your preferences by clicking on your profile picture.
3. Then click on Statistics.

Available statistics during a meeting

The next time you access Statistics for meetings and phone, the following tabs will appear and you will be able to see the diagnostic info:

Overall

• CPU: Refers to the processor’s speed and the amount of cores on the computer. This bar chart displays the amount of time Zoom is using the computer’s processor compared to how much time the computer is using in general.
• Memory: Memory refers to how much memory is available to each individual computer. There are bars that indicate the amount of memory that Zoom is consuming in comparison to the overall amount of memory being utilised.
• Bandwidth: Provides you with information about how much data Zoom is currently sending. You can check the bandwidth used by Zoom by visiting Speedtest. Zoom recommends that HD videos are uploaded and downloaded at a bandwidth of 1.2Mbps.
• Network Type: The Network Type button displays whether your connection is wired or wireless.
• Proxy: Lets you know whether you have a proxy server or not. The account owner or the administrator of your account should change your proxy server settings if you are experiencing problems connecting to Zoom through a proxy server.
• Connection Type: This refers to the type of data protocol used by the participant.
• Data Center: During the meeting, the participant will connect to the Zoom data center and the meeting will begin.
• My Encryption Algorithm: All participants will be able to communicate with each other during the meeting.
  There is a need to encrypt the meeting content with cryptographic keys which are unique to the devices of the participants of that meeting.
• Version: Zoom Desktop gives you the version number of the Zoom desktop client that you are using at the moment.

Audio, Video, and Screen Sharing

• Frequency (only applies to audio): Sample rate used to send and receive audio. It is generally acceptable to use a sample rate ranging from 16 to 48 kHz. Audio quality improves at higher frequencies.
• Latency: How long it takes a packet to travel from sender to receiver. We recommend a latency of no more than 150ms. Delays between video and audio will be noticeable when the latency is higher than 150ms. You can calculate the time between the time when you speak and the time when the other user receives your audio.
• Jitter: A variation in packet arrival time caused by congestion in the network, timing drift or route changes that causes packets to arrive at different times. As a general rule of thumb, jitter should be no more than 40 milliseconds.
• Packet Loss – Average(Max): How much data is lost in the process of transport to the destination? Generally speaking, there should be a packet loss of less than 2%.
• Resolution (only applies to video): In each dimension, the number of pixels that your video camera can display in the frame. The higher the resolution, the higher the quality. I would recommend a resolution of 1280 by 720 pixels. To see our recommendations for HD cameras, click here.
• Frames Per Second (only applies to video): Is a measure of how fast your video camera is able to capture a frame in time. Zoom supports frames rates as high as 30 frames per second. As a rule of thumb, a frame rate of around 30 frames per second is recommended. You can read more about the cameras we recommend here.

Available statistics during a phone call

The Phone tab in Zoom Phone can also be used to view diagnostic data during a Zoom Phone call if you have a Zoom Phone license.

Note: It is possible to see two sets of statistics for each call participant if you have added a call or merged a two-way call into a three-way call.

Phone

• Register ID: For troubleshooting issues with network connectivity to the Zoom Phone server, Zoom may ask to see this register ID. Please click the Copy button when you see this ID.
• Register Server IP/Port: This is the IP address of the Zoom Phone server the user is connected to.
• Network Switch: In the event the switch is not the user’s own, the device’s own network switch.
• Local Network Interface: Typically, the Zoom Phone service is connected to an internal network card, which can be used by the user to access the Zoom Phone service locally.
• Peer Number: This is the phone number of the person you are calling.
• Local IP and Port: Those are the IP and port numbers for your local computer. Your Zoom phone’s network settings should be changed by your admin if you are experiencing issues with your phone.
• Remote IP and Port: This address and port is used to make the call from a remote location.
• Network Delay: The time it takes for a packet to travel from sender to receiver. In general, it is recommended that your latency is less than 150ms. If your latency is higher than 150ms, the callers will notice noticeable delays during the call. There is a possibility that, as a result of the delay in sending and receiving audio, call participants may often talk over one another.
• Packet: For codec bit rates to be provided, the codec packets per second (PPS) must be transmitted every second. Around 50 PPS is considered normal.
• Frequency: Refers to the frequency at which the audio is sent and received. As a rule of thumb, sampling rates between 16 and 48kHz are generally considered acceptable. The higher the sampling rate, the better the audio quality will be.
• Packet Loss – Average(Max): Data that is not received at its final destination as a result of packet loss. A packet loss rate of less than 2% is considered acceptable.
• Jitter: An increase in the amount of time between the arrival of packets due to network congestion, packet time drift, or route changes. Generally, it is recommended that the jitter is under 40ms.
• Bandwidth: This indicator is used to display how much data is currently being transmitted by Zoom. For more information on your current bandwidth, please visit Speedtest. In general, the recommended bitrate for a high-quality voice is 60–100kbps.
• Codec: Zoom Phone uses a codec to encode the audio. It is usually Opus that is used, an audio codec that is sure to provide excellent sound quality.

Available statistics for VDI

I would suggest you review the following article for more information on the VDI statistics available in the Zoom desktop client.

How to identify quality issues

Identifying issues with quality can be difficult if you do not have the right warning markers.

• It is possible that there is a quality issue when the color is orange.
• It is possible that there is a quality issue when the color is red.
• An exclamation mark (!) is a signal that there is an issue with the quality of a tab that you aren’t presently viewing.
