You can call this operation to query byte hit ratios collected at intervals of one minute for one or more specified accelerated domains.

When you call this operation, follow these rules:
  • You can only query the data within the last seven days in each call. The time range specified by the StartTime and EndTime parameters cannot exceed 24 hours for a query.
  • If StartTime is specified and EndTime is not specified, the data for the one-hour period starting from the specified StartTime value is returned.
  • If EndTime is specified and StartTime is not specified, the data for the last hour preceding the specified EndTime value is returned.
  • The network traffic destined for different domain names may be redirected to the same origin. Therefore, the returned byte hit ratios may be inaccurate. The accuracy of query results depends on the actual configurations.


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.
