Queries request hit ratios for one or more accelerated domains. The data is collected every minute.

Before you call this operation, pay attention to the following notes:
  • You cannot specify only one of the StartTime and EndTime parameters. If you specify neither StartTime nor EndTime, the data in the last hour is returned.
  • The network traffic destined for different domain names may be redirected to the same origin. Therefore, the returned request hit ratios may be inaccurate. The accuracy of query results depends on the actual configurations.

Debugging

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.
