August 2017 Summaries

Video publishing involves a complex network of systems that need to work together seamlessly for successful video playback. Mux and Cedexis have partnered to offer real-time CDN switching, making millisecond-level routing decisions to improve the performance and reliability of video delivery. CDNs can have inconsistent geographic performance, compatibility issues with ISPs, outages, and human errors that affect video Quality of Experience (QoE). Cedexis tracks internet delivery performance through real user measurements and reroutes traffic around congestion and outages, while Mux collects, processes, and analyzes streaming video events to identify QoE issues. Together, they provide accurate monitoring and improve the effectiveness of using multiple CDNs for better performance and cost savings.

The text discusses recent changes made to aggregate metric charts, focusing on improving how individual video views are understood by customers. Previously, events were represented as bars in a timeline with corresponding colors, but this approach lacked clarity and user-friendliness. To address these issues, the new design includes a legend for event categories, an x-axis to indicate when events occurred, improved error metrics, more detailed hover information, explicit marking of user-initiated events, and zoom functionality. These improvements aim to provide better insight and actionability for users.

In January 2017, Mux introduced error-rate alerts in their analytics service and aimed to calculate adaptive thresholds for these alerts. However, they realized that many of the generated alerts were not significant or actionable, leading to alert fatigue among users. To address this issue, Mux trained a binary classifier using historical alert incident details to identify important alert conditions. This feature has significantly reduced the volume of alerts and increased the visibility of crucial alerts. Users are encouraged to try the alerts feature in the Mux analytics service and provide feedback for further improvements.
