CAT indices

Introduced 1.0 {: .label .label-purple }

The CAT indices operation lists information related to indices⁠—how much disk space they are using, how many shards they have, their health status, and so on.

Example

GET _cat/indices?v

{% include copy-curl.html %}

To limit the information to a specific index, add the index name after your query.

GET _cat/indices/<index>?v

{% include copy-curl.html %}

If you want to get information for more than one index, separate the indices with commas:

GET _cat/indices/index1,index2,index3

{% include copy-curl.html %}

Path and HTTP methods

GET _cat/indices/<index>
GET _cat/indices

All CAT indices URL parameters are optional.

In addition to the common URL parameters, you can specify the following parameters:
