This topic describes the features, benefits, and billing of real-time log delivery.

Features

When you use DCDN, a large amount of network log data is generated. Real-time log delivery allows you to collect logs that are generated by points of presence (POPs) in real time and deliver the collected logs to Log Service for storage and consumption. This helps you monitor your business and identify service issues in an efficient manner.

Usage notes

The traffic usage of accelerated domain names that is queried by using the monitoring or resource usage feature available in the Alibaba Cloud DCDN console or by calling API operations differs from that collected in logs. Typically, the traffic usage of accelerated domain names that is queried by using the monitoring or resource usage feature is 1.1 times that collected in logs. For more information, see Why is the actual billed network traffic different from the network traffic reported by the logging feature?

Benefits

  • High timeliness: After you enable the real-time log delivery feature, log data is automatically delivered to Log Service. You can view the real-time log analysis results for logs that are generated within the previous 3 minutes in the Log Service console.
  • Multiple fields: Real-time logs contain multiple log fields. For more information, see Log fields.
  • Business compliance: The collection and delivery processes of real-time logs are compliant.
  • Powerful data analysis: Log Service can work together with DCDN. Visualized analysis templates are generated for logs after the logs are delivered from DNCN to Log Service. This helps you analyze and monitor your business changes in an efficient manner. Scenarios:
    • Fine-grained analysis on URLs: You can analyze the trend in the number of requests from a URL, the profile of the requests from a specific location or source IP address, and the availability of a URL.
    • Analysis on business reliability: You can analyze the error codes that are returned from requested URLs, error domain names, error URLs, and error IP addresses.
    • Analysis on networks: You can analyze the response latency and cache hit ratio of networks.
    • Profile analysis: You can analyze profiles based on geographic locations, terminals, and source IP addresses.
