This topic describes the features, scenarios, benefits, and billing methods of real-time log delivery.
What is real-time log delivery?
When you use Dynamic Route for CDN (DCDN) to accelerate content delivery, a large amount of logs are generated. You can use DCDN to collect logs that are dynamically generated and deliver the logs to Log Service or a specified location for log analytics in real time. You can analyze the collected logs to troubleshoot issues and make business decisions at the earliest opportunity.
For more information, see Log Service.
You can use real-time log delivery to troubleshoot issues that may occur when you use DCDN to accelerate your domain name. You can also use the collected logs to analyze user statistics.
For traditional log analytics, you must download logs, upload the logs to a data warehouse, perform data scrubbing and modeling, and then analyze the logs. These steps consume large amount of effort and time. The real-time log delivery feature of DCDN can be used to collect logs with low latency and monitor your DCDN service. After you activate DCDN, logs of DCDN are automatically delivered to Log Service. This simplifies the data analysis process and allows you to view the analysis results at your convenience.
Differences between real-time log delivery and log downloads
The following list shows the differences between real-time log delivery and log downloads:
- Real-time log delivery is used to dynamically collect logs. The delay between the time when logs are generated and when logs are collected is at most three minutes. DCDN integrates with Log Service to implement log analysis. This allows you to analyze logs, troubleshoot issues, and make business decisions at the earliest opportunity.
- When you download offline logs, the delay is usually less than 24 hours. However, the delay may also exceed 24 hours.
You are charged based on the number of logs that are pushed in real time.For more information about the pricing of real-time log collection, see Pricing of value-added services.
You are separately charged for Log Service. For more information about the billing methods of Log Service, see Pricing of value-added services.
