Query a list of DDoS attack events with DescribeDDosAllEventList - Anti-DDoS - Alibaba Cloud - Anti-DDoS

Queries the list of DDoS attack events.

Operation description

This operation is used to query the list of DDoS attack events within a specified time range by using paging. DDoS attack events contain the following information: attack start time and end time, attack type, attacked object, and peak attack traffic (peak bandwidth or peak packet forwarding rate).

Rate limit

The single-user QPS limit for this operation is 10 calls per second. If the limit is exceeded, API calls are throttled, which may affect your business. Invoke this operation at an appropriate frequency.

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.

Request parameters

Parameter	Type	Required	Description	Example
EventType	string	No	The type of DDoS attack event to query. Valid values: web-cc: web resource exhaustion attack. cc: connection flood attack. defense: volumetric attack (scrubbing event). blackhole: volumetric attack (blackhole filtering event). You can specify multiple types. Separate them with commas (,). If you do not set this parameter, attack events of all types are queried.	defense
StartTime	integer	Yes	The beginning of the time range to query. DDoS attack events that occurred after StartTime are queried. Specify a UNIX timestamp. Unit: seconds. Note StartTime can specify only events within the last three months.	1609430400
EndTime	integer	Yes	The end of the time range to query. DDoS attack events that occurred before EndTime are queried. Specify a UNIX timestamp. Unit: seconds. Note EndTime can specify only events within the last three months.	1640966399
PageNumber	integer	Yes	The page number to return in a paging query.	1
PageSize	integer	Yes	The number of attack events to return on each page in a paging query.	10
Ip	string	No	The IP address of the Anti-DDoS Pro or Anti-DDoS Premium instance to query.	192.168.1.1

When you call this operation, you must include Alibaba Cloud common request parameters in addition to the request parameters described in this topic. For more information about common request parameters, see Common parameters.
