Querying Details About ECSs

Function

This API is used to query details about ECSs.

URI

GET /v2.1/{project_id}/servers/detail?changes-since={changes-since}&image={image}&flavor={flavor}&name={name}&status={status}&limit={limit}&marker={marker}&not-tags={not-tags}&reservation_id={reservation_id}&ip={ip}

GET /v2/{project_id}/servers/detail?changes-since={changes-since}&image={image}&flavor={flavor}&name={name}&status={status}&limit={limit}&marker={marker}&not-tags={not-tags}&reservation_id={reservation_id}&ip={ip}

Table 1 describes the parameters in the URI.

Table 1 Path parameters

Parameter

Mandatory

Description

project_id

Yes

Specifies the project ID.

Table 2 Query parameters

Parameter

Mandatory

Type

Description

changes-since

No

String

Specifies the timestamp of the last ECS status update, which is used to filter out the ECSs with statuses updated later than the timestamp. The format must comply with ISO 8601 in the format of CCYY-MM-DDThh:mm:ss+/-hh:mm, for example, 2018-01-17T03:03:32Z.

image

No

String

Specifies the image ID.

When image is used as a filter criterion, other filter criteria and paging criteria are not supported. If both the image and other filter criteria are specified, the image filter criterion is used. If the query criteria do not contain the image filter criterion, API functions are not restricted.

flavor

No

String

Specifies the ECS flavor ID, which is fuzzy-matched.

name

No

String

Specifies the ECS name, which is fuzzy-matched.

status

No

String

Specifies the ECS status.

Options:

ACTIVE, BUILD, ERROR, HARD_REBOOT, MIGRATING, REBOOT, REBUILD, RESIZE, REVERT_RESIZE, SHUTOFF, and VERIFY_RESIZE

In microversion 2.37, the system will return an empty list for the status field out of the preceding options. In microversion 2.38 and later, the system will return error 400.

For details, see ECS Statuses.

limit

No

Integer

Specifies the upper limit on the number of returned results.

Each page contains 25 ECSs by default, and a maximum of 1,000 ECSs are returned. For large data volumes, you are advised to set this parameter to 100.

marker

No

String

Specifies the ECS ID to which the marker points. The query will start from its next ID.

tags

No

String

Queries ECSs with tags containing the specified value.

For details about key rules, see Tag Types.

Note

Tag functions have been upgraded on the cloud platform. If the tags added before the function upgrade are in the format of "Key.Value", query tags using "Key".

For example, an existing tag is a.b. After the tag function upgrade, query the tag using "not-tags=a".

reservation_id

No

String

Specifies the ID returned when ECSs are created in a batch. This parameter is used to query ECSs created in a batch.
