Note

This panel is automatically hidden when you have more than 30 accelerated domain names.

Domain name dashboard

This section displays the total count of accelerated domain names in your account, categorized by status: Enabled, Disabled, and Configuring.

Enabled domains dashboard

For all domain names in the Enabled state, this dashboard shows the number of domains that are Not Configured or Configured for the following items: CNAME, Cache Expiration Time, and SSL Certificate. Hovering over a count displays the domain names for the corresponding configuration state.

Parameter	Required	Description
CNAME	Required	A CNAME record is a type of DNS record. This configuration is required to ensure that your accelerated domain name functions correctly with Alibaba Cloud CDN.
Cache Expiration Time	Recommended	The cache expiration time specifies how long Alibaba Cloud CDN points of presence (POPs) cache resources from your origin server. When this time expires, POPs mark the cached content as invalid. A proper cache expiration time improves the cache hit ratio and reduces content delivery latency.
SSL Certificate	Recommended	An SSL certificate encrypts data transferred between clients and Alibaba Cloud CDN POPs, allowing your accelerated domain name to be accessed over HTTPS.

Access data

This panel displays statistics for Bandwidth, Traffic, and Requests for all accelerated domain names in your account for different time ranges, such as Today, Yesterday, and Last 7 Days.

Click the > button next to a time range to open the Usage Query page. From there, you can query data for a specific accelerated domain name or view more detailed access data for a custom time range.

Status code

This module displays statistics for HTTP status codes received by clients for different time dimensions, such as Today, Yesterday, and Last 7 days, including the number and proportion of 2xx Success, 4xx Client Error, and 5xx Server Error responses.

For example, the percentage of 4xx Client Error responses is the ratio of 4xx Client Errors to the total number of edge responses.

Click the > button for the time dimension to query data for a single accelerated domain name or more detailed HTTPCODE data within a custom time range on the Resource Monitoring page.

2xx Success - Edge Response: A client request was successfully processed by the POP, which returned the requested resource or a confirmation.

4xx Client Error-Edge Response: The POP could not process the client request due to an error in the request, such as insufficient permissions. Modify and resend the client request.

4xx Client Error-Origin Fetch Response: The origin server could not process the POP's request due to an error, such as a non-existent resource. Modify the client request or your CDN domain configuration, then resend the request.

5xx Server Error-Edge Response: An internal error occurred on the POP while processing a client request, possibly due to high server load. Check your origin server's network configuration.

5xx Server Error-Origin Fetch Response: An internal error occurred on the origin server while processing a POP's request, possibly due to high server load. Check your origin server's configuration and load.

Billing method

Important

Detailed usage information for resource plans is displayed only when the billing method for basic services billing (Traffic) is pay-by-data-transfer.
If the billing method for basic services billing (Traffic) is not pay-by-data-transfer, purchased resource plans are not used to offset costs. Instead, fees are deducted from your account balance.
