CAT shards
Introduced 1.0 {: .label .label-purple }
The CAT shards operation lists the state of all primary and replica shards and how they are distributed.
Example
GET _cat/shards?v
{% include copy-curl.html %}
To see only the information about shards of a specific index, add the index name after your query.
GET _cat/shards/<index>?v
{% include copy-curl.html %}
If you want to get information for more than one index, separate the indexes with commas:
GET _cat/shards/index1,index2,index3
{% include copy-curl.html %}
Path and HTTP methods
GET _cat/shards

All cat shards URL parameters are optional.
