DescribeDcdnDomainHitRateData-阿里云帮助中心

Queries the byte hit ratio of a domain name.

Operation description

The call frequency per user is 100 calls per second.
If StartTime and EndTime are not specified, the data of the last 24 hours is queried by default. If StartTime and EndTime are specified, the data within the specified time range is queried.

Supported query time granularity

The request parameter Interval supports different time granularities for data timestamps based on the maximum time span of a single query. The corresponding queryable historical data range and data latency are as follows:

Time granularity	Maximum time span for a single query	Queryable historical data range	Data latency
5 minutes	3 days	93 days	15 minutes
1 hour	31 days	186 days	Typically 3 to 4 hours
1 day	366 days	366 days	Typically 4 hours, up to 24 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.

Request parameters

Parameter	Type	Required	Description	Example
DomainName	string	No	The accelerated domain name. Only a single domain name is supported. If you do not specify this parameter, all domain names are queried by default.	example.com
StartTime	string	No	The start time of the data to query. Specify the time in the ISO 8601 standard in the yyyy-MM-ddTHH:mm:ssZ format. The time must be in UTC.	2018-03-02T12:00:00Z
EndTime	string	No	The end time of the data to query. Specify the time in the ISO 8601 standard in the yyyy-MM-ddTHH:mm:ssZ format. The time must be in UTC. The end time must be later than the start time.	2018-03-02T15:00:00Z
Interval	string	No	The time granularity of the data to query. Unit: seconds. Valid values: 300 (5 minutes), 3600 (1 hour), and 86400 (1 day). The supported values vary based on the maximum time span of a single query. For more information, see Supported time granularities above.	300
