== Cluster Stats
|
|
|
|
The Cluster Stats API allows to retrieve statistics from a cluster wide perspective.
|
|
The API returns basic index metrics (shard numbers, store size, memory usage) and
|
|
information about the current nodes that form the cluster (number, roles, os, jvm
|
|
versions, memory usage, cpu and installed plugins).
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
curl -XGET 'http://localhost:9200/_cluster/stats?human&pretty'
|
|
--------------------------------------------------
|
|
|
|
Will return, for example:
|
|
["source","js",subs="attributes,callouts"]
|
|
