Under settings, we’ve added a feature of being able to see the send/receive rate of audio, video, and screen sharing during a call as well as overall system performance. This add-on will allow you to gauge whether you are experiencing issues during your meeting.
Check your Bandwidth
You can to to http://speedtest.net to check your network bandwidth. Generally, we recommend 1.2 to 1.5Mbps upload/download for an optimal experience on desktop or room systems.
How to Use Diagnostics
When in a meeting, select Video Settings or Audio Options. Then select Statistics.
Once “Settings” has been opened, you can view varying statistics during the call.
To understand this better, a few terms will need to be understood.
- Latency - The delay between packet being sent and received. For example the time between you speaking and the other user receiving the audio on their end.
- Jitter - The variation in the time between packets arriving, caused by network congestion, timing drift, or route changes.
- Packet Loss - The total amount of data that fails to reach the final destination.
- Resolution - The number of pixels in each dimension that can be displayed. Higher usually means higher quality.
- Frames Per Second - The rate at which the device can produce unique images, or frames.
Audio statistics will provide the frequency, latency, jitter, and packet loss experienced during a call, as seen here.
Video statistics is quite similar, adding the resolution of video being sent and received, as well as the frames per second.
Screen Sharing statistics are identical to video, showing the resolution of the screen being shared, as well as the frames per second.
When sharing a Screen with others, the “Receive” field will be left blank, and when viewing another shared screen, the send field will be left blank. This is shown below.
Finally, we have given overall system performance to see how much of your CPU and RAM is being used during the meeting. This shows the send and receive rate you are experiencing during the call. Higher bandwidth numbers usually indicate a stronger connection.
Finally, there are two types of warnings once in the statistics. Orange indicates that there may be some quality issues as shown here with packet loss in audio.
Red indicates that there most likely will be quality issues, as seen in the packet loss of audio seen here.
A red exclamation point indicates there is an issue with a tab you currently are not on.
