- Troubleshoot website access exceptions
Log Service has been configured to collect DDoS logs, you can query and analyze the collected logs in real time. Using SQL statement to analyze the DDoS access log, you can quickly check and analyze the website access exceptions, and view information such as read and write delays and operator distribution.For example, view the DDoS access log by using the following statement:
- Track CC attack source
The distribution and source of CC attacks are recorded in the DDoS access log. By performing real-time query and analysis on the DDoS access log, you can conduct source tracking, trace CC attacks, and provide a reference for response strategy.For example, analyze the CC attack country distribution recorded in the DDoS access log by the following statement:
__topic__: ddos_access_log and cc_blocks > 0| SELECT ip_to_country(if(real_client_ip='-', remote_addr, real_client_ip)) as country, count(1) as "number of attacks" group by country
For example, view the PV access by the following statement:
__topic__: ddos_access_log | select count(1) as PV
- Website operation analysis
DDoS access log records the website access data in real time. You can perform SQL query analysis of the collected access log data to obtain real-time access status, such as determining the website popularity, the source and channel of the access, the client distribution, and assist in website operation analysis.For example, view the visitor traffic distribution from different network clouds:
__topic__: ddos_access_log | select ip_to_provider(if(real_client_ip='-', remote_addr, real_client_ip)) as provider, round(sum(request_length)/1024.0/1024.0, 3) as mb_in group by provider having ip_to_provider(if(real_client_ip='-', remote_addr, real_client_ip)) <> '' order by mb_in desc limit 10
