Querying Flavors

Function

This API is used to query all load balancer flavors that are available to a specific user in a specific region.

Constraints

This API has the following constraints:

  • Parameters marker, limit, and page_reverse are used for pagination query.

  • Parameters marker and page_reverse take effect only when they are used together with parameter limit.

Calling Method

For details, see Calling APIs.

URI

GET /v3/{project_id}/elb/flavors

Table 1 Path Parameters

Parameter

Mandatory

Type

Description

project_id

Yes

String

Specifies the project ID.

Table 2 Query Parameters

Parameter

Mandatory

Type

Description

marker

No

String

Specifies the ID of the last record on the previous page.

Note:

  • This parameter must be used together with limit.

  • If this parameter is not specified, the first page will be queried.

  • This parameter cannot be left blank or set to an invalid ID.

limit

No

Integer

Specifies the number of records on each page.

page_reverse

No

Boolean

Specifies whether to use reverse query.

Value options:

  • true: Query the previous page.

  • false (default): Query the next page.

Note:

  • This parameter must be used together with limit.

  • If page_reverse is set to true and you want to query the previous page, set the value of marker to the value of previous_marker.

id

No

Array of strings

Specifies the flavor ID.

Multiple IDs can be queried in the format of id=xxx&id=xxx.

name

No

Array of strings

Specifies the flavor name.

Multiple names can be queried in the format of name=xxx&name=xxx.

type

No

Array of strings

Specifies the flavor type.

Value options:

  • L4 indicates a Layer-4 flavor.

  • L7 indicates a Layer-7 flavor.

  • L4_elastic indicates the minimum Layer-4 flavor for elastic scaling. L7_elastic indicates the minimum Layer-7 flavor for elastic scaling.

  • L4_elastic_max indicates the maximum Layer-4 flavor for elastic scaling. L7_elastic_max indicates the maximum Layer-7 flavor for elastic scaling.

Multiple types can be queried in the format of type=xxx&type=xxx.

shared

No

Boolean

Specifies whether the flavor is available to all users.

  • true indicates that the flavor is available to all users.

  • false indicates that the flavor is available only to a specific user.

public_border_group

No

Array of strings

Specifies the public border groups.

Multiple public border groups can be queried in the format of public_border_group=xxx&public_border_group=xxx.

category

No

Array of integers

Specifies the categories.

Multiple categories can be queried in the format of category=xxx&category=xxx.

list_all

No

Boolean

If list_all is set to true, all maximum elastic specifications defined by l4_elastic_max and l7__elastic_max are returned. If list_all is set to false, only the largest elastic specifications will be returned. For layer 4 load balancers, the specification with highest cps value is returned. If the cps values are the same, the specification with highest bandwidth value is returned. For layer 7 load balancers, the specification with highest https_cps value is returned. If the https_cps values are the same, the specification with highest *qps value is returned.
