List shards
Introduced 2.18
The list shards operation outputs, in a paginated format, the state of all primary and replica shards and how they are distributed.
Path and HTTP methods
GET _list/shards
GET _list/shards/<index>
Query parameters
All parameters are optional.
| Parameter | Type | Description |
|---|---|---|
bytes | Byte size | Specifies the byte size units, for example, 7kb or 6gb. For more information, see Supported units. |
local | Boolean | Whether to return information from the local node only instead of from the cluster manager node. Default is false. |
cluster_manager_timeout | Time | The amount of time to wait for a connection to the cluster manager node. Default is 30s. |
cancel_after_time_interval | Time | The amount of time after which the shard request is canceled. Default is -1 (no timeout). |
time | Time | Specifies the time units, for example, 5d or 7h. For more information, see Supported units. |
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 and minimum value is 2000. Maximum value is 20000. |
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 and shards, use the following query and keep specifying the next_token as received from response until its null:
GET _list/shards/<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 and keep specifying the next_token as received from response until its null:
GET _list/shards/<index>?v&next_token=token
If you want to get information for more than one index, separate the indexes with commas, as shown in the following example:
GET _list/shards/index1,index2,index3?v&next_token=token
