You can download a CDN access log for the last 30 days, which contains the details of every request made to VOD. Logs are recorded hourly.
- No access logs will be generated for a day on which there is no request received, and you will see "No Data" on the page.
- By default, the CDN logs requests on an hourly basis, that is, there can be up to 24 log files generated per day. No logs will be generated for the hour in which there is no request received.
- CDN logs can be delayed by approximately 30 minutes.
Decompress the downloaded log data packages and view the log files in text format. The fields are separated by space. Below is an example:
|2||IP of the client accessing the domain name|
|3||Accessed domain name|
|4||File request path|
|5||Number of bytes of this access request|
|6||District; for more information, please see district mappings below|
|7||ISP; for more information, please see ISP mappings below|
|8||HTTP status code|
|10||Response time in milliseconds|
|14||HTTP protocol identifier|
The bandwidth or traffic data recorded in logs is the returned data at the application layer (HTTP protocol), which is smaller than that calculated at the TCP layer due to such factors as TCP protocol packet loss, three-way handshake, and retransmission.
