The Health score for Sources is a predictor of stream quality for the coming two hour period. The health score is determined based on ML algorithms (part of Zixi's Intelligent Data Platform) that assess over 100 measurements of the Source's performance. A score from 0 to 100 indicates the overall health of the Source. A low health score indicates a likelihood of an offline event or packet loss occurring within the next two hours.
The Health graph shows the Health score as well as the measures that contribute to the determination of the Health score.
Health score is an add-on feature that needs to be activated in your ZEN Master account in order for the data to be shown. |
Health score is only available for Zixi Sources. |
Hovering the mouse on any point in the graph displays additional data for the following parameters in the Health graph:
Health Score – a score from 0 to 100 indicating the health of the Source, as a predictor of stream quality over the coming two hours.
Not Recovered – the count of not recovered packets.
Network Congestion – a measurement of network congestion.
Offline Prediction – a score from 0 to 100 predicting the likelihood of an offline event occurring in the coming two hours.
Not Recovered Prediction – a score from 0 to 100 predicting the likelihood of packet loss occurring in the coming two hours.
Network Anomaly – a score from 0 to 100 indicating the degree of anomalous activity occurring on the Source.
You can get additional information about the main metrics that contributed to the fluctuation of the Health Score at a particular time period by selecting a time period (up to 2 hr) on the graph and clicking on Explain Offline or Explain not Recovered Predictions. This opens a bar graph showing the main metrics that fluctuated at that time and the extent to which they contributed to the change in Health Score.
Network Graph
The Network Graph, which is presented in parallel to the Health graph, provides context related to the network activity that is occurring within the selected timeframe.
Hovering the mouse on the any point on the graph or any other graph on this screen, displays additional data for the following parameters:
Not recovered packets – the number of packets that were not recovered.
Dropped packets – the number of packets that were dropped.
Recovered packets – the number of packets that were recovered.
Retransmitted packets – the number of packets that were retransmitted.
RTT (max) – the highest Round Trip Time (RTT) from the Source, in milliseconds.
RTT (min) - the lowest Round Trip Time (RTT) from the Source, in milliseconds.
Jitter (max) - the maximum Jitter, in milliseconds.
Jitter (min) - the minimum Jitter, in milliseconds.
Connection Graph
The Connection Graph, which is presented in parallel to the Health graph, provides context related to the connection activity that is occurring within the selected timeframe.
Hovering the mouse on the any point on the graph or any other graph on this screen, displays additional data for the following parameters:
Network Bitrate – the bitrate level of the network traffic.
Reconnections – the number of reconnections.
Packet Timing Graph
The Packet Timing Graph, which is presented in parallel to the Health graph, provides context related to the timing of packets traffic.
Hovering the mouse on the any point on the graph or any other graph on this screen, displays additional data for the following parameters:
Max – the maximum packet timing.
75th percentile – the packet timing in the 75th percentile.
25th percentile – the packet timing in the 25th percentile
Min - the minimal packet timing
