Can anyone please direct me where I can find information about what the different colors of Call Statistics /Advanced/Stats A mean?
The screenshot you've added above is the "Advanced" call statistics window on the installable desktop client. In summary it's a graphical representation of the call performance statistics. In most cases reviewing the call statistics overview is more than enough to determine if there a call performance or connectivity issue cause by the IP networks the client is traversing to establish a peer to peer connection with Lifesize Cloud and/or the far-end caller.
Nonetheless, to answer your question... the horizontal rows on your screen shot represent the different data streams being received and transmitted during the call. The rows break down as follows...
The larger (left hand) columns/cells represent a time-based graph of the call performance (in blue). The title summary above each graph provides instantaneous values for various metrics such as the current frame rate and packet loss etc.
The smaller (right hand) columns/cells represent the same data over a much shorter (circa 5 second) period. With the smaller horizontal bars showing instantaneous usage on each frame/packet.
I hope this helps to explain?
If you're having challenges with video call performance, or need assistance deciphering how this data can help you to identify issues with your network connectivity and call experience.

Thanks for the information. I can see what each row means.Still, what does the light blue mean? I can see it is not constant.
Is there any documentation about it? even as part of one certification/course?
And yes, I will contact support when a get a consistence and clear issue to be solved.
The "light blue" on the graph is showing the utilisation of bandwidth over time. I've actually added some highlights / markers on your screen shot below In this case it looks like the network connection between the client, Lifesize Cloud and the far-end (whatever that was) was not performing perfectly.
You can see in your screen shot, that the Video Tx is consuming less bandwidth (circa 500kbps) and has actually stepped down, probably as a result of packet loss on the peer-to-peer connection. There are also specific point on the Rx graph which shows clear drops in data, probably again caused by packet loss. As you can see this corresponds on both Audio and Video Rx graphs.
There is no specific "training" which we provide to explain the advanced diagnostics and analysis of call statistical data. This is just one tool that our in house support engineers and technicians from our Lifesize partners can utilise to assist customers to diagnose performance issues with their calls and networks. If you'd like to lean more, I'd suggest contacting our local Lifesize Sales Engineer in Australia rwinefield who may able able to assist further.
