Sentry ABR

 

Proactively Monitor ABR Content Throughout Your Network

Sentry ABR is a post-origin measurement device that focuses on QoS. Sentry ABR is an active monitoring product that proactively monitors ABR content on origin servers or CDN caching servers.  It does this by actively requesting and validating program playlists / manifests that it has been configured to monitor.  It then requests from the server, in turn, all of the fragments of each profile / representation for each program – calculating availability and performance metrics and generating alerts in real time. 

Sentry ABR can operate as a stand alone monitor, or as an extension to an existing Sentry / Medius deployment providing a unified platform for both linear broadcast and ABR video service monitoring.
Key Features
  • Supports Apples HTTP Live Streaming and MPEG DASH protocols with HTTP statistics
  • Proactively monitors all available ABR media and network from content acquisition (source) to the edge of the network
  • Fetches playlist/manifest files and fragments from any place on the network (e.g., origin servers or CDN caching servers) to validate availability and performance of all profiles
  • Validates all assets, bitrate profiles, and manifest files based on a highly parallel HTTP fragment fetching engine
  • Top level manifest file validation is used to automatically discover the sub-stream manifest URLs, fetched in real time at the manifest-indicated rate
  • Alerts on any mismatch in the bitrate of the sub streams; missing segments (HTTP errors); and excessive segment-fetching latency
  • Reports on the availability of all input manifests (programs) over the network, and their sub streams in the familiar Sentry-product style
  • A reduced input bitrate mode is available for customers sensitive to monitoring equipment "load
  • Supports existing alert functionality and reporting capability (including alert dashboard, and program availability, with 60-day historical reporting).
  • Supports up to 250 top manifests
  • Supports both 1G and 10G interfaces
