# 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
|
||
```
|
||
|
||
To limit the information to a specific index, add the index name after your query.
|
||
|
||
```
|
||
GET _cat/indices/<index>?v
|
||
```
|
||
|
||
If you want to get information for more than one index, separate the indices with commas:
|
||
|
||
```json
|
||
GET _cat/aliases/index1,index2,index3
|
||
```
|
||
|
||
## Path and HTTP methods
|
||
|
||
```
|
||
GET _cat/indices/<index>
|
||
GET _cat/indices
|
||
```
|
||
|
||
## URL parameters
|
||
|
||
All CAT indices URL parameters are optional.
|
||

||
