In the VOD Console, you can view statistics of bandwidth/traffic, storage capacity, and transcoding.
In addition, VOD provides data analysis of the number of requests and number of access requests from unique IPs by domain name/region/ISP. For playback statistics, it also supports querying file playbacks by
FileId and top 100 videos played back.
The number of requests refers to the number of all playback requests sent to CDN in a certain period of time. This data contains statistics from all sources, including Tencent Cloud Player, webpages, and custom players.
The number of requests is related to the video format: if the format is MP4, it equals to the number of playbacks; if the format is HLS, it equals to the number of requests for M3U8 and TS parts. This value is updated once every five minutes.
Each CDN edge server of VOD collects traffic data in real time and reports it to the computing center which aggregates the data into total traffic data of the domain name and displays the converted bandwidth statistics by time duration, used traffic, or time.
The traffic counted based on the downstream bytes in the log of an acceleration domain name in VOD is only about the data at the application layer.
The traffic generated during actual data transfer over the network is around
5–15% more than application-layer traffic:
3–10%packets are lost on the internet, and the server will retransmit the lost ones. This type of traffic cannot be counted by the application layer, which accounts for
3–7%of the total traffic.
As an industry standard, the billable traffic is the sum of the application-layer traffic and the overheads as described above. VOD increases the application-layer monitoring statistics by 10%, so the billable accelerated traffic (as displayed in the usage statistics) is about
110% of the accelerated traffic calculated in the log.
