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.

Required

Description

Example

RegionId

string

No

The region ID of the Alibaba Cloud Global Accelerator (GA) instance. Set the value to cn-hangzhou.

cn-hangzhou

ClientToken

string

No

The client token that is used to ensure the idempotence of a request.

The client generates the value of this parameter. Ensure that the value is unique among different requests. The value can contain up to 64 ASCII characters.

Note

If you do not specify this parameter, the system uses the RequestId of the API request as the ClientToken. The RequestId may be different for each API request.

TaskName

string

The name of the origin probing task.

task1

Address

string

The URL or IP address to be probed.

https://www.aliyun.com

OptionsJson

string

The advanced extension options for the listener protocol type of the origin probing task. Different listener protocol types correspond to different extension options.

{ "http_method": "get","header": "key:asd","acceptable_response_code": "500","cert_verify": true }

IspCityList

array<object>

The list of ISP detection points.

object

The list of ISP detection points.

Isp

string

The ID of the ISP detection point.

465

IspName

string

The name of the ISP detection point.

Alibaba

City

string

The ID of the city where the ISP detection point is located.

375

CityName

string

The name of the city where the ISP detection point is located.

Singapore

DetectEnable

boolean

Indicates whether the automatic diagnostics feature is enabled.

  • true: Enabled.

  • false: Disabled.

true

DetectThreshold

integer

The threshold that triggers automatic diagnostics.

Automatic diagnostics is triggered when the origin availability rate falls below the threshold.

0

DetectTimes

integer

The number of times the threshold must be reached to trigger automatic diagnostics.

1

SilenceTime

integer

The silence period for automatic diagnostics. This specifies the interval between automatic diagnostics triggers when the availability rate has not recovered to normal after automatic diagnostics is triggered.

When the availability rate falls below the automatic diagnostics threshold for consecutive times (the value specified by DetectTimes), automatic diagnostics is triggered. If the availability rate remains below the threshold during the silence period, automatic diagnostics is not triggered again within the silence period. If the availability rate has not recovered to normal after the silence period ends, automatic diagnostics is triggered again.

Unit: seconds.

cn-hangzhou

State

string

The status of the origin probing task. Valid values:

  • init: Initializing.

  • active: Active.

  • updating: Being configured.

  • inactive: Inactive.

  • deleting: Being deleted.
