# 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.
In addition to the [common URL parameters]({{site.url}}{{site.baseurl}}/opensearch/rest-api/cat/index#common-url-parameters), you can specify the following parameters:
Parameter | Type | Description

health | String | Limit indices based on their health status. Supported values are `green`, `yellow`, and `red`.
include_unloaded_segments | Boolean | Whether to include information from segments not loaded into memory. Default is false.
