While VIDIZMO's CDN improves user experience and allows you to achieve efficiency in your network resource utilization, you can also monitor increased network traffic and balance network performance without compromising on the user experience with the use of Quality of Service (QoS) for networks. QoS is an industry-wide set of standards and mechanisms for ensuring high-quality performance for critical applications and is widely used by network administrators to make efficient use of existing resources and to ensure the required level of service is achieved without overwhelming the network.


To learn more, read Understanding Media Quality of Experience (QoE).


Here is how you can analyze your media and its views:


Steps

1. From the Homepage, log using a Moderator+ role and navigate to the Media Manager.



2. From the Media Manager:

i. Select the video to view its QoS.

ii. The video shows up as the selected on the left-hand side.

iii. Click on the QoS button to bring up the QoS screen (iv).





3. The QoS screen displays the following information:

  • Views & Viewers: This panel shows the number of times and the number of viewers who watched the video




  • Time Played: Among all the views, this is the maximum length the video has been watched so far.
  • Load Time: This represents the average time taken by the video to load the first frame.




  • Player Buffering: Average buffering during video playback. Buffering is measured at three levels - high, average and low
  • Player Errors: These are the errors that are caused by events such as network disconnection from the video source, video unavailability or for any reason the player crashes.




  • Player Load Time is also displayed as a graph and in a tabular form, with high, average and low load times measured against locations.

i. & ii. Click on the graph legends on the chart to show or hide data on the graph. The legend for the excluded data appears as crossed-out.

iii. The Pie Chart and List icons allow you to toggle between Graphical and Tabular views.

iv. Using the Download icon, you can also download the information in a .csv format.

iv. Hovering over the bar displays the information as a tooltip. In the example below, it shows 8 secs for the location marked as Zurich. 

v. The same information displayed in a tabular form.





  • Cache Hits: This chart displays user requests received by the Origin and Edge servers across the network. 

i. Cache Hits chart.

ii. Hovering over a section displays the hit count for that server.




  • Device Buffering: If users experience buffering during video playback, the system records the percentage of buffering that took place during the duration of playback. Device buffering is monitored over each device used to access the video.

i. Graphical view by device type.

ii. Tabular view by device type. On the Buffering column, use the double arrows to sort values in ascending or descending order.




  • Device Buffering Heat Map: The Geographical Heat Map is automatically populated based on the location from where the video was accessed the most

i. Buffering Heat Map graphical view

ii. Toggled view with details on location and percentage 





  • Device Errors: These are the errors that are caused by events such as network disconnection from the video source, video unavailability or for any reason the player crashes.

i. Graphical view by device type.

ii. Tabular view by device type. On the Buffering column, use the double arrows to sort values in ascending or descending order.




  • Error Heat Map: The Error Heat Map identifies locations where the errors are occurring during playback.

i. Error Heat Map - graphical view with locations.

ii. Toggled view with details on location and number of errors. 





  • Video Quality Playing: This chart represents video qualities played during the entire playback duration. In the example below, 50% of the time, the video was rendered at 720.

i. Graphical view showing video quality played during playback.

ii. The view can be toggled to display data in a tabular form.
