Use DescribeVodDomainRealTimeReqHitRateData to query real-time request hit ratio - ApsaraVideo VOD - Alibaba Cloud - ApsaraVideo VOD

Operation description

Currently, this operation is supported only in the China (Shanghai) region.
Batch queries are supported. You can query data for up to 100 domain names at a time.
If you do not specify StartTime and EndTime, this operation returns data for the last 1 hour by default. If you specify StartTime and EndTime, this operation returns data for the specified time range.
The Go language uses the POST method by default. Manually change the request method to GET by declaring request.Method="GET".

Time granularity of returned data

The time granularity of returned data varies based on the time range specified by StartTime and EndTime. The following table describes the queryable historical data range and data latency for each time granularity:

Time granularity	Time range per query	Queryable historical data range	Data latency
1 minute	Time range per query ≤ 1 hour	7 days	5 minutes
5 minutes	1 hour < Time range per query < 3 days	93 days	15 minutes
1 hour	3 days ≤ Time range per query < 31 days	186 days	Typically 3 to 4 hours

Test

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.
