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.

AcceleratorId

string

The ID of the GA instance on which the origin probing task runs.

ga-bp1odcab8tmno0hdq****

ListenerId

string

The ID of the listener on which the origin probing task runs.

lsr-bp1bpn0kn908w4nbw****

TaskId

string

The origin probing task ID.

sm-bp1fpdjfju9k8yr1y****

TaskName

string

The origin probing task name.

task1

Address

string

The URL or IP address that was probed.

https://www.aliyun.com

OptionsJson

string

The extended options of the listener protocol that is used by the origin probing task. The options vary based on the listener protocol.

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

DetectEnable

boolean

Indicates whether the automatic diagnostics feature is enabled. Valid values:

  • true

  • false

true

DetectThreshold

integer

The threshold that is used to trigger the automatic diagnostics feature.

1

DetectTimes

integer

The number of times that are required to reach the threshold before the automatic diagnostics feature can be triggered.

1

SilenceTime

integer

The silence period of the automatic diagnostics feature. This parameter indicates the interval at which the automatic diagnostics feature is triggered. If the availability rate does not return to normal after GA triggers an automatic diagnostic task, GA must wait until the silence period ends before GA can trigger another automatic diagnostic task.

If the number of consecutive times that the availability rate drops below the threshold of automatic diagnostics reaches the value of DetectTimes , the automatic diagnostics feature is triggered. The automatic diagnostics feature is not triggered again within the silence period even if the availability rate stays below the threshold. If the availability rate does not return to normal after the silence period ends, the automatic diagnostics feature is triggered again.

Unit: seconds.

300

State

string

The status of the origin probing task. Valid values:

  • active: The origin probing task is running.

  • inactive: The origin probing task is stopped.

  • init: The origin probing task is being initialized.

  • deleting: The origin probing task is being deleted.
