The cluster stats api now returns counts for each node role. The `master_data`, `master_only`, `data_only` and `client` fields have been removed from the response in favour of `master`, `data`, `ingest` and `coordinating_only`. The same node can have multiple roles, hence contribute to multiple roles counts. Every node is implicitly a coordinating node, so whenever a node has no explicit roles, it will be counted as coordinating only.

== 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"]
