Monitoring tools for iOS

Introduction

On top of the stats API exposed by the SDK, we created a view helper called LumenStatsView to help you integrate and understand Mesh Delivery faster. The LumenStatsView will inform you about the different states of the SDK lifecycle and Lumen metrics.

 

 

The view looks like the following:

Statsview For CDN Load Balancer

Note: LumenStatsView is NOT intended for production

Adding a LumenStatsView is really simple. A helper method is available to display various CDN Load Balancer related stats on a specified UIView.

                // The implementer is in charge to create the view and to display it on top of the player controller/layer
self.deliveryClient.displayStatWiew(someView!)
            
                // The implementer is in charge to create the view and to display it on top of the player controller/layer
plugin.displayStatsView(someView!)

Note: Our sample app is using AVPlayerViewController, on iOS we are adding the view as a subview of AVPlayerViewController. On tvOS, we suggest to use customOverlayViewController instead.

What do the stats tell you?

The LumenStatsView shows the following information regarding the performance and scores for each CDN in the CDN list being used.

Parameter Description Unit

Download

Total amount of bytes downloaded from the CDN

MB

Bandwidth


The estimated bandwidth of the CDN

MB/s

Global score

Global CDN score, calculated as global score = QoS score * business score

  

Business score

User defined score which controls the level of priority of a CDN based on your own business requirements. It can take an integer value between 1 and 100

 

QoS score

Denotes a score for the quality of service that the user is receiving. Each session can have a different QoS score and is measured from actual performance (like rebuffering events, dropped frames, etc.)


 

Error count

Number of HTTP errors received from the CDN.
