:Functions and features

Last Updated:Jul 28, 2023

Alibaba Cloud CDN provides a wide array of functions and features that you can use to manage domain names added to Alibaba Cloud CDN. You can use these features to monitor domain names, query monitoring data, refresh and prefetch resources, manage logs, query IP addresses, query events, manage SLS certificates, enable protection, and manage resource quotas.

Note To help you understand and obtain up-to-date information about Alibaba Cloud CDN, operations that you can perform in the console are classified into domain management features and service management features.

The following table describes the service management features.




Monitoring and usage analytics

Resource monitoring

Allows you to query information about domain names accelerated by Alibaba Cloud CDN so that you can monitor the performance of Alibaba Cloud CDN. The information includes network traffic, bandwidth, back-to-origin network traffic, back-to-origin bandwidth, the number of requests, the number of queries per second, cache hit ratios, HTTP status codes, and HTTP status codes returned to requests that are redirected to the origin servers.

Real-time monitoring

Allows you to query basic information about your accelerated domain names, back-to-origin network traffic, and the acceleration performance in real time. The basic information about accelerated domain names includes bandwidth, network traffic, the number of requests, and the number of queries per second. Allows you to detect anomalies in network traffic and locate errors at the earliest opportunity.

Query resource usage

Allows you to query statistics such as network traffic, bandwidth, requests, and real-time log entries in regions outside or inside the Chinese mainland, and check the billable items and metering data of Alibaba Cloud CDN.

ES monitoring

Allows you to query the execution status of scripts for a specified accelerated domain name. You can check whether scripts are executed at the edges as expected.

Refresh and prefetch

Refresh and prefetch resources

The refresh feature removes resources from edge nodes and enables edge nodes to redirect requests to origin servers. The prefetch feature prefetches resources from origin servers to edge nodes during off-peak hours and accelerates content delivery.

Log management

Download logs

Allows you to query and download log data of specified domain names within specified time periods.

Grant a RAM user permissions on log storage

Authorizes Resource Access Management (RAM) users to activate or manage the log storage feature. In addition, you can attach policies to RAM users to implement fine-grained permission control.

Use Function Compute to deliver logs

To retain log data for a longer period of time, import the log data to Object Storage Service (OSS). This allows you to analyze the log data at any time.

Customize an operations report template and create a tracking task

Allows you to query offline analytics data of accelerated domain names in specified time periods. You can gain insights into the status of accelerated domain names and your business by analyzing the data.

IP tool

Query IP addresses

Allows you to query whether an IP address belongs to an edge node, and the region and Internet service provider (ISP) to which an IP address belongs.

Event query

Query events about Alibaba Cloud CDN

Allows you to use ActionTrail to query events about Alibaba Cloud CDN. You can view the time, region, and domain name of an event.

Certificate Management Service

Configure an SSL certificate for multiple domain names

SSL certificates are used to encrypt data transmission between clients and servers. This enables secure and efficient retrieval of resources from origin servers.

Query SSL certificates of domain names

Allows you to query SSL certificates configured for your domain names, and check the status of the certificates.


Configure high bill alerts

Protects domain names from attacks and flooding. This can prevent high bills caused by spikes in data transfer or bandwidth usage.

Introduction to sandboxes

Provides causes of sandboxed domain names and relevant solutions.

RAM user permission management

Manage Alibaba Cloud CDN as a RAM user

Allows you to use RAM users to manage domain names by group. You can grant RAM users permissions on different API operations as needed to regulate access control.

Authorize a RAM user to prefetch and refresh resources

Allows you to grant RAM users permissions on the refresh or prefetch operation by attaching system or custom policies to the RAM users.

Revoke the permissions that allow a RAM user to change the metering method

Allows you to use custom policies to forbid RAM users from changing the metering method of Alibaba Cloud CDN.
