You can download the detailed log containing the information about users' access to a connected domain for analysis; CDN provides logs about domains on an hourly basis, and you can download CDN logs for the last 30 days.

Log Download

Log in to CDN Console and select Logs page. You'll see the Log Management feature provided by CDN.

Select the domain for which you want to check logs and the date range, then click Query to get the log download link, and click the link to download:

If there was no request for the domain on that day, no log would be generated. In this case, "No Data" will appear.

Note:

  • CDN logs are provided on an hourly basis by default, with 24 log files generated each day;
  • CDN logs have a latency of about half an hour in terms of real-timeness and will not be updated after 2 hours.
