CDN:Configure real-time log delivery

FAQ

How do I migrate real-time logs for a CDN domain to a different Logstore or a new Alibaba Cloud account?

The process depends on whether you are migrating within the same account or to a new one.

Migrating to a different Logstore within the same account

Simply modify the existing real-time log delivery task to point to the new Logstore (e.g., from logstore1 to logstore2). Data delivery will continue to the old Logstore until the change is fully propagated, after which it will switch to the new Logstore without interruption.

Migrating a domain to a different Alibaba Cloud account

To prevent data loss and incorrect billing, you must follow these steps in order:

1. In Account 1, disable the real-time log delivery task for the domain.

2. Migrate the domain from Account 1 to Account 2.

3. In Account 2, create a new real-time log delivery task for the domain.

Is it possible to temporarily pause and later resume real-time log delivery?

Yes. You can pause and resume log delivery for a specific domain or Logstore without losing your configuration. The association between the domain and the Logstore is preserved while paused.

You can use the following API operations or the equivalent options in the console:

• To pause delivery: Call DisableRealtimeLogDelivery.

• To resume delivery: Call EnableRealtimeLogDelivery.

How can I query the CDN log data after it has been delivered to SLS?

All queries must be performed directly within the destination Simple Log Service (SLS) Project and Logstore. Once the data is in SLS, you can:

• Query all log data for a specific user within a defined time range.

• Query all data delivered to a particular Logstore.

Procedure

1. Log on to the 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 SLS parameters.

   

   Parameter	Description
   Project Name	The name of the SLS Project. The name must be unique across all your Projects in the SLS console.
   Logstore Name	A Logstore is a resource collection within a Project. All data in a Logstore originates from the same data source. Queries, analysis, and delivery of collected log data are performed on a per-Logstore basis. If you leave this field empty, Alibaba Cloud CDN automatically generates a name for the Logstore.
   Region	The Region where the destination SLS Logstore is located.
   Log Service Role	Click Authorize. Go to the Resource Access Management (RAM) page to grant the AliyunCDNLogArchiveRole permission.

5. Once authorized, click Next.

6. Select and associate one or more domain names. Then, select the checkbox to acknowledge the billing details and click Create.

   

   Note

   • The real-time log delivery list displays only the Logstores associated with your Alibaba Cloud CDN domain names, not all Logstores in your account.

   • You can associate up to five domain names at a time.

   • After data is delivered to the Logstore, you can view four default reports. You can access these reports directly from the Alibaba Cloud CDN console.

7. Click OK.

   On the task tab, you can view the number of successful and failed log delivery attempts.
