Analytics Overview Completion Ratio
The completion ratio provides visibility into the percent of downloads where the content was completely downloaded. For delivery on files, completion ratio provides visibility into end user behavior and is often an indicator of elective download cancellation. If the entire file is downloaded, completion ratio is 100%. If an end user electively cancels a download, this can affect your download completion ratio.
For delivery on videos, completion ratio can show if the videos are popular and watched longer by the audience. For example, if a viewer begins to watch a video and decides to change videos or end their session before watching the entire video, then completion ratio shows the percent of video downloaded or viewed. Because Highwinds delivers progressively downloaded video faster than the end user can watch them, completion ratio for video over progressive download is only accurate when bandwidth throttling is implemented. Bandwidth throttling is discussed in another section of the CDN user's guide.
By selecting the Completion Ratio button in the Overview Area, charts are displayed showing Completion ratio for the current month, including Total GB delivered, Attempted GB, and the Calculated Completion Ratio. Data for the prior 11 months is shown to use as comparison.
Completion Ratio Percentage
The Completion Ratio Percentage chart displays the completion ratio percentage for each day in the current month. Hovering over the graph displays the completion ratio aggregating the data in 1 hour intervals.
The completion ratio is calculated by dividing the number of bytes actually received by the end user divided by the number of bytes initially requested or attempted.
Total Delivery by Data Center
The Total Delivery by Data Center chart is a Donut Pie Chart displaying worldwide delivery, broken down by CDN region (inner pie circle) and POP (outer pie circle) for the current month. The percentage of delivery and total number of GB delivered is provided when hovering over each Pie area.
The top Sites for the account is shown, with the total Number of GB delivered, the bytes that were attempted to be delivered, and the calculated Completion Ratio for the top Sites in the account. The top Sites shown in this area include only the direct Sites for that account and do not include Subaccount Sites.
