Querying Details About EVS Snapshots

Function

This API is used to query details about the EVS snapshots.

URI

• URI format

  GET /v2/{project_id}/snapshots/detail

• Parameter description

  Parameter	Mandatory	Description
  project_id	Yes	The project ID. For details about how to obtain the project ID, see Obtaining a Project ID.

• Request filter parameters

  Parameter	Type	Mandatory	Description
  marker	String	No	The ID of the resource from which pagination query starts. It is the ID of the last resource on the previous page.
  offset	Integer	No	The query offset. NOTE: This parameter is used when snapshots are queried by page and is used together with the limit parameter. For example, there are a total of 30 snapshots. If you set offset to 11 and limit to 10, the query starts from the twelfth snapshot, and a maximum of 10 snapshots can be queried at a time.
  limit	Integer	No	The maximum number of query results that can be returned. The value ranges from 1 to 1000, and the default value is 1000. The returned value cannot exceed this limit. If the tenant has more than 50 snapshots in total, you are advised to use this parameter and set its value to 50 to improve the query efficiency. Examples are provided as follows: GET /v2/xxx/snapshots/detail?limit=50: Queries the 1–50 snapshots. GET /v2/xxx/snapshots/detail?offset=50&limit=50: Queries the 51–100 snapshots.
  name	String	No	The snapshot name, which can contain a maximum of 255 bytes.
  status	String	No	The snapshot status. For details, see EVS Snapshot Status.
  volume_id	String	No	The ID of the snapshot's source disk.
  availability_zone	String	No	The AZ where the snapshot's source disk belongs.
