=== Nodes usage
|
|
|
|
The cluster nodes usage API allows to retrieve information on the usage
|
|
of features for each node.
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
GET _nodes/usage
|
|
GET _nodes/nodeId1,nodeId2/usage
|
|
--------------------------------------------------
|
|
// CONSOLE
|
|
// TEST[setup:node]
|
|
// TEST[s/nodeId1,nodeId2/*/]
|
|
|
|
The first command retrieves usage of all the nodes in the cluster. The
|
|
second command selectively retrieves nodes usage of only `nodeId1` and
|
|
`nodeId2`. All the nodes selective options are explained
|
|
<<cluster-nodes,here>>.

==== REST actions usage information
|
|
|
|
The `rest_actions` field in the response contains a map of the REST
|
|
actions classname with a count of the number of times that action has
|
|
been called on the node:
