Use DescribeDomainReqHitRateData to query the request hit ratio - CDN - Alibaba Cloud - CDN

Queries the request hit ratio (the percentage of hit requests).

Operation description

If you do not specify StartTime and EndTime, this operation returns data for the last 24 hours. If you specify StartTime and EndTime, this operation returns data for the specified time range.

Supported time granularities

Based on the maximum time span of a single query, the request parameter Interval supports different data timestamp granularities. The corresponding time range of historical data that can be queried and data delay are as follows:

Time granularity	Maximum time span for a single query	Time range of historical data that can be queried	Data delay
5 minutes	3 days	93 days	15 minutes
1 hour	31 days	186 days	Generally 3 to 4 hours
1 day	90 days	366 days	Generally 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.
