List indices

Introduced 2.18

The list indices operation provides the following index information in a paginated format:

  • The amount of disk space used by the index.
  • The number of shards contained in the index.
  • The index’s health status.

Path and HTTP methods

GET _list/indices
GET _list/indices/<index>

Query parameters

Parameter Type Description
bytes Byte size Specifies the units for the byte size, for example, 7kb or 6gb. For more information, see Supported units.
health String Limits indexes based on their health status. Supported values are green, yellow, and red.
include_unloaded_segments Boolean Whether to include information from segments not loaded into memory. Default is false.
cluster_manager_timeout Time The amount of time to wait for a connection to the cluster manager node. Default is 30s.
pri Boolean Whether to return information only from the primary shards. Default is false.
time Time Specifies the time units, for example, 5d or 7h. For more information, see Supported units.
expand_wildcards Enum Expands wildcard expressions to concrete indexes. Combine multiple values with commas. Supported values are all, open, closed, hidden, and none. Default is open.
next_token String Fetches the next page of indexes. When null, only provides the first page of indexes. Default is null.
size Integer The maximum number of indexes to be displayed on a single page. The number of indexes on a single page of the response is not always equal to the specified size. Default is 500. Minimum is 1 and maximum value is 5000.
sort String The order in which the indexes are displayed. If desc, then the most recently created indexes are displayed first. If asc, then the oldest indexes are displayed first. Default is asc.

When using the next_token path parameter, use the token produced by the response to see the next page of indexes. After the API returns null, all indexes contained in the API have been returned.

Example requests

To get information for all the indexes, use the following query and keep specifying the next_token as received from response until its null:

GET _list/indices/<index>?v&next_token=token

To limit the information to a specific index, add the index name after your query, as shown in the following example:

GET _list/indices/<index>?v

To get information about more than one index, separate the indexes with commas, as shown in the following example:

GET _list/indices/index1,index2,index3?v&next_token=token
