DescribeDomainRealTimeTrafficData - CDN - Alibaba Cloud Documentation Center

Queries the monitoring data of network traffic for one or more accelerated domain names.

Operation Description

You can call this operation up to 50 times per second per account.
If you do not specify the StartTime or EndTime parameter, the request returns the data collected in the last hour. If you specify 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.

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

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

Operation: the value that you can use in the Action element to specify the operation on a resource.
Access level: the access level of each operation. The levels are read, write, and list.
Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
Condition Key: the condition key that is defined by the cloud service.
Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Operation	Access level	Resource type	Condition key	Associated operation
cdn:DescribeDomainRealTimeTrafficData	READ	CDN acs:cdn:*:{#accountId}:domain/{#DomainName}	none	none
