Queries byte hit ratios for one or more accelerated domain names.

Description

  • You can call this operation up to 10 times per second per account.
  • The network traffic destined for different domain names may be redirected to the same origin server. Therefore, the byte hit ratios may be inaccurate. The accuracy of query results is based on the actual configurations.
  • If you do not set the StartTime or EndTime parameter, the request returns the data collected in the last hour. If you set both the StartTime and EndTime parameters, the request returns the data collected within the specified time range.
Time granularity

The time granularity varies with the time range specified by the StartTime and EndTime parameters. The following table describes the time period within which historical data is available and the data delay.
