You can call the DescribeDomainAverageResponseTime operation to query the average response time of the specified CDN domain names.

  • If you do not set the StartTime and EndTime parameters, the data within the last 24 hours is queried.
  • If you set both the StartTime and EndTime parameters, the data within the specified time range is queried.
Note
  • You can query either one domain name or all domain names under your account.
  • The maximum time range that you can specify is the last 90 days.

Debugging

Alibaba Cloud provides OpenAPI Explorer to simplify API usage. You can use OpenAPI Explorer to search for APIs, call APIs, and dynamically generate SDK example code.
