Nodes Feature Usageedit

Nodes usageedit

The cluster nodes usage API allows to retrieve information on the usage of features for each node.

GET _nodes/nodeId1,nodeId2/usage
GET _nodes/usage

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 here.

REST actions usage informationedit

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:

{
  "_nodes": {
    "total": 1,
    "successful": 1,
    "failed": 0
  },
  "cluster_name": "my_cluster",
  "nodes": {
