DescribeDcdnDomainRealTimeTrafficData - Edge Security Acceleration

Operation description

The throttling limit for a single user is 50 calls per second.

Data time granularity

The time granularity of the returned data varies based on the time range that you specify using the StartTime and EndTime parameters. The following table describes the time granularity, maximum time range per query, queryable historical data range, and data latency.

Time granularity	Maximum time range per query	Queryable historical data range	Data latency
1 minute	1 hour	7 days	5 minutes
5 minutes	3 days	93 days	15 minutes
1 hour	31 days	186 days	Typically 3 to 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.

Request parameters

Parameter	Type	Required	Description	Example
DomainName	string	Yes	The accelerated domain name. You can specify multiple domain names. Separate them with commas (,).	example.com
StartTime	string	No	The beginning of the time range to query. Specify the time in the ISO 8601 standard in the yyyy-MM-ddTHH:mm:ssZ format. The time must be in Coordinated Universal Time (UTC). Note If you do not specify StartTime and EndTime, data in the last hour is queried. If you specify both StartTime and EndTime, data in the specified time range is queried.	2015-12-10T20:00:00Z
EndTime	string	No	The end of the time range 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. Note If you do not specify StartTime and EndTime, data in the last hour is queried. If you specify both StartTime and EndTime, data in the specified time range is queried.	2015-12-10T20:01:00Z
