Introduced 1.0
{: .label .label-purple }

The CAT indices operation lists information related to indexes, that is, how much disk space they are using, how many shards they have, their health status, and so on.
2021-06-22 02:13:40 -04:00
## Example
```
GET _cat/indices?v
```
{% include copy-curl.html %}
2021-06-22 02:13:40 -04:00
To limit the information to a specific index, add the index name after your query.
```
GET _cat/indices/<index>?v
```
{% include copy-curl.html %}
2021-06-22 02:13:40 -04:00
If you want to get information for more than one index, separate the indices with commas:
```json
GET _cat/indices/index1,index2,index3
2021-06-22 02:13:40 -04:00
```
{% include copy-curl.html %}
2021-06-22 02:13:40 -04:00
## Path and HTTP methods
```
GET _cat/indices/<index>
GET _cat/indices
```
## URL parameters
All CAT indices URL parameters are optional.
