=== cat indices API

|

|
Returns high-level information about indices in a cluster, including backing
|
|
indices for data streams.

[[cat-indices-api-request]]
|
|
==== {api-request-title}
|
|
|
|
`GET /_cat/indices/<target>`
|
|
|
|
`GET /_cat/indices`
|
|
|
|
|
|
[[cat-indices-api-desc]]
|
|
==== {api-description-title}
|
|
|
|
Use the cat indices API to get the following information for each index in a
|
|
cluster:
|
|
|
|
* Shard count
|
|
* Document count
|
|
* Deleted document count
|
|
* Primary store size
|
|
* Total store size of all shards, including shard replicas
|
|
|
|
These metrics are retrieved directly from
|
|
https://lucene.apache.org/core/[Lucene], which {es} uses internally to power
|
|
indexing and search. As a result, all document counts include hidden
|
|
<<nested,nested>> documents.
|
|
|
|
To get an accurate count of {es} documents, use the <<cat-count,cat count>> or
|
|
<<search-count,count>> APIs.

`<target>`::
|
|
(Optional, string)
|
|
Comma-separated list of data streams, indices, and index aliases used to limit
|
|
the request. Wildcard expressions (`*`) are supported.
|
|
+
|
|
To target all data streams and indices in a cluster, omit this parameter or use
|
|
`_all` or `*`.
