CDN：Real-time log delivery

Concepts

• Transfer the log data of a domain name to another Logstore: For example, Domain A is associated with Logstore 1 but the log data of Domain A must be transferred to Logstore 2. Before you associate Domain A with Logstore 2, the log data of Domain A is delivered to Logstore 1. After you associate Domain A with Logstore 2, the existing log data of Domain A is transferred from Logstore 1 to Logstore 2. The new log data is directly delivered to Logstore 2. During this process, log delivery is not interrupted.

  Important

  Before you transfer Domain A from Account 1 to Account 2, you must disable real-time log delivery for Domain A in Account 1. After you transfer Domain A to Account 2, you can enable real-time log delivery for Domain A in Account 2. If you do not perform the preceding operations, real-time logs are still delivered to Account 1. This incurs charges to Account 1.

• Disable or enable real-time log delivery: You can disable or enable real-time log delivery, disable the delivery of log data to a specific Logstore, and disable the delivery of log data of a specific domain name to Simple Log Service. In the preceding scenarios, the domain name remains associated with the Logstore.

• Query log data: You can query data within a specific period of time, all data of a specific visitor, or data delivered to a specific Logstore.

Procedure

1. Log on to the Alibaba Cloud CDN console.

2. In the left-side navigation pane, choose Logs > Real-time Logs.

3. On the Real-time Logging tab, click Activate Real-Time Log Push Service.

4. In the Create Real-time Log Delivery Task dialog box, configure the parameters. The following table describes the parameters.

   

   Parameter	Description
   Project Name	Enter a name for the Simple Log Service project to which log data of Alibaba Cloud CDN is delivered. The project name must be unique among the projects in the Simple Log Service console.
   Logstore Name	A Logstore is a set of resources created in a project. All data in a Logstore originates from the same source. The collected log data is queried, analyzed, and delivered by Logstore. If you do not specify a name for the Logstore, Alibaba Cloud CDN automatically specifies a name for the Logstore.
   Region	The region of the Logstore to which logs are delivered.
   Log Service Role	After you click Authorize, the Cloud Resource Access Authorization page appears. Click Confirm Authorization Policy to assign the AliyunCDNLogArchiveRole role to Alibaba Cloud CDN.

5. After the authorization is complete, click Next.

6. Select domain names that you want to associate with the Logstore and then click Create.

   

   Note

   • The log delivery list displays only the Logstore that stores log data of domain names accelerated by Alibaba Cloud CDN. Other Logstores within your Alibaba Cloud account are not displayed in the list.

   • You can associate up to five domain names with a Logstore.

   • After log data is delivered to the specified Logstore, the data is presented in four reports. You can access and view these reports in the Alibaba Cloud CDN console.

7. Click OK.

   On the Real-time Log Data tab, you can view the numbers of successful real-time log deliveries and failed real-time log deliveries.
