Call DescribeDomainRealTimeByteHitRateData to query the real-time byte hit ratio of domain names - CDN

Operation description

Each account can call this operation up to 10 times per second.
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.
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.

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.

Time granularity	Maximum time range per query	Historical data available	Data delay
1 minute	1 hour	7 days	5 minutes
5 minutes	3 days	93 days	15 minutes
1 hour	31 days	186 days	4 hours

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
