CAT indices
Introduced 1.0
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.
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 indexes with commas:
GET _cat/indices/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, you can specify the following parameters:
