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}

Table 1 describes the parameters in the URI.

**Table 1** Path parameters
Parameter	Mandatory	Description
project_id	Yes	Specifies the project ID. For details about how to obtain the ID, see Obtaining a 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.
not-tags	No	String	Queries ECSs with tags not containing the specified value. The value is the tag key. 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.
sort_key	No	String	Sorts query results by ECS attribute. The default sorting order is the reverse order of created_at. The value can be created_at, auto_disk_config, availability_zone, display_description, display_name, host, host_name, image_ref, instance_type_id, kernel_id, key_name, launch_index, launched_at, locked_by, node, power_state, project_id, ramdisk_id, reservation_id, root_device_name, task_state, terminated_at, user_id, updated_at, uuid, or vm_state.
ip	No	String	Indicates the filtering result for IPv4 addresses, which are fuzzy-matched.
