Querying the Migration Rate Limit Rules of a Migration Task

Function

This API is used to query the time segment-based migration rate limiting rules of a migration task.

Calling Method

For details, see Calling APIs.

URI

GET /v3/tasks/{task_id}/speed-limit

Table 1 Path parameter

Parameter

Mandatory

Type

Description

task_id

Yes

String

The ID of the task for which you want to query the rate limit rules

Minimum length: 0 characters

Maximum length: 255 characters

Request

Table 2 Request header parameter

Parameter

Mandatory

Type

Description

X-Auth-Token

Yes

String

X-Auth-Token

The user token. The token can be obtained by calling the IAM API used to obtain a user token. The value of X-Subject-Token in the response header is the user token.

Minimum length: 1 character

Maximum length: 16,384 characters

Response

Status code: 200

Table 3 Response body parameters

Parameter

Type

Description

speed_limit

Array of SpeedLimitlJson objects

The information about the time segments when the migration rate is limited.

Array length: 0 to 65,535

Table 4 SpeedLimitlJson field description

Parameter

Type

Description

start

String

The start time of a segment. The format is XX:XX.

Minimum length: 0 characters

Maximum length: 255 characters

end

String

The end time of a segment. The format is XX:XX.

Minimum length: 0 characters

Maximum length: 255 characters

speed

Integer

The migration rate limit for the specified period of time. The value is an integer ranging from 0 to 1000. The unit is Mbit/s.

Minimum value: 0

Maximum value: 10000

over_speed_threshold

Double

The overspeed threshold for stopping migration. This is a protection measure. If the migration speed exceeds the threshold, the task is stopped. It is used to control the consumption of resources (especially network bandwidth) during the migration to ensure that the overall system performance is not affected by a single migration task. The unit is percentage.

Minimum value: 0

Maximum value: 100

Status code: 403

Table 5 Response body parameters

Parameter

Type

Description

error_code

String

The error code.

Minimum length: 0 characters

Maximum length: 255 characters

error_msg

String

The error message.

Minimum length: 0 characters

Maximum length: 255 characters

encoded_authorization_message

String

Encrypted authorization information.

Minimum length: 0 characters

Maximum length: 65,535 characters

error_param

Table 6 details field description

Parameter

Type

Description

error_code

The SMS error code.

Minimum length: 0 characters

Maximum length: 65,535 characters

error_msg

String

The SMS error message.

Minimum length: 0 characters

Maximum length: 65,535 characters

Example Request

This example queries the migration rate limit rules for a migration task.

GET https://{endpoint}/v3/tasks/7a9a9540-ff28-4869-b9e4-855fbe12xxxx/speed-limit

Example Response

Status code: 200

The migration rate limiting rules of a migration task were obtained.
