You can call this operation to query hit ratios collected at intervals of one minute for one or more 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 you do not set StartTime and EndTime, the data for the last hour is returned.
  • If StartTime is specified and EndTime is not specified, the data in 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 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.

Error codes

HTTP status code Error code Error message Description
400 MissingTimeParameter The StartTime and EndTime must be both specified. The error message returned because the StartTime and EndTime parameters must be specified at the same time.
400 InvalidStartTime.Malformed The specified StartTime is invalid. The error message returned because the format of the specified StartTime parameter is invalid. Specify the time in the ISO 8601 standard in the yyyy-MM-ddTHH:mm:ssZ format. The time must be in UTC.
400 InvalidEndTime.Malformed The specified EndTime is invalid. The error message returned because the format of the specified EndTime parameter is invalid. Specify the time in the ISO 8601 standard in the yyyy-MM-ddTHH:mm:ssZ format. The time must be in UTC.
400 InvalidEndTime.Mismatch The specified EndTime is earlier than the StartTime. The error message returned because the specified EndTime parameter is earlier than the specified StartTime parameter.
400 InvalidStartTime.ValueNotSupported The specified StartTime is invalid. The error message returned because the specified StartTime parameter is invalid.
