Updated at November 26, 2024

Retrieves a list of hosts for the specified Elasticsearch cluster.

gRPC request

rpc ListHosts (ListClusterHostsRequest) returns (ListClusterHostsResponse)

ListClusterHostsRequest

{
  "cluster_id": "string",
  "page_size": "int64",
  "page_token": "string"
}

Field

Description

cluster_id

string

Required field. ID of the Elasticsearch cluster.

To get the Elasticsearch cluster ID, make a ClusterService.List request.

page_size

int64

The maximum number of results per page to return.

If the number of available results is larger than page_size, the service returns a ListClusterHostsResponse.next_page_token that can be used to get the next page of results in subsequent list requests.

page_token

string

Page token.

To get the next page of results, set page_token to the ListClusterHostsResponse.next_page_token returned by the previous list request.

ListClusterHostsResponse

  "hosts": [
    {
      "name": "string",
      "cluster_id": "string",
      "zone_id": "string",
      "type": "Type",
      "resources": {
        "resource_preset_id": "string",
