The cluster nodes usage API allows you to retrieve information on the usage of features for each node. All the nodes selective options are explained here.

Path parameters

edit

<metric>

(Optional, string) Limits the information returned to the specific metrics. A comma-separated list of the following options:

_all: Returns all stats.
rest_actions: Returns the REST actions classname with a count of the number of times that action has been called on the node.

<node_id>

(Optional, string) Comma-separated list of node IDs or names used to limit returned information.

Query parameters

edit

timeout: (Optional, time units) Period to wait for each node to respond. If a node does not respond before its timeout expires, the response does not include its information. However, timed out nodes are included in the response’s _nodes.failed property. Defaults to no timeout.

Examples

edit

Rest action example:

resp = client.nodes.usage()
print(resp)

response = client.nodes.usage
puts response

const response = await client.nodes.usage();
console.log(response);

GET _nodes/usage

The API returns the following response:

{
  "_nodes": {
    "total": 1,
    "successful": 1,
    "failed": 0
  },
  "cluster_name": "my_cluster",
  "nodes": {
    "pQHNt5rXTTWNvUgOrdynKg": {
      "timestamp": 1492553961812, 
      "since": 1492553906606, 
      "rest_actions": {
        "nodes_usage_action": 1,
        "create_index_action": 1,
        "document_get_action": 1,
