Queries byte hit ratios of an accelerated domain name. The data is collected at an interval of one minute. You can query data collected within the last seven days.

  • The time range specified by the StartTime and EndTime parameters cannot exceed 24 hours.
  • If you do not set StartTime or EndTime, data collected within the last one hour is queried. If you set both StartTime and EndTime, data collected within the specified time range is queried.
  • The network traffic destined for different domain names may be redirected to the same origin server. Therefore, the cache hit ratios may be inaccurate. The accuracy of query results is based on the actual configurations.
  • The maximum number of times that each user can call this operation per second is 10.
  • You can specify multiple domain names (no more than 100) and separate them with commas (,).


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
