This tab allows you to monitor one or more channels. Use the “Channel” dashboard to select the channel or channels you want to monitor.
Click the <Add metric to graph> icon associated with each channel to add one or multiple graphs. Select a unique color for each graph to make it easy to identity.

Video quality: Aggregation of all four metrics
MOS: Mean Opinion Score; perceived video quality
Blur: Image sharpness
