Returns cluster statistics Added in 1.3.0
It 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).
Path parameters
-
Comma-separated list of node filters used to limit returned information. Defaults to all nodes in the cluster.
Query parameters
-
include_remotes boolean
Include remote cluster data into the response
-
timeout string
Period to wait for each node to respond. If a node does not respond before its timeout expires, the response does not include its stats. However, timed out nodes are included in the response’s
_nodes.failedproperty. Defaults to no timeout.
