Hello to everyone!  
How can I check cluster helth of Elasticsearch 6.1 through Java code (maybe through Java high level rest client)?  
In Rest it will be `GET _cluster/health`.

info() should give you some information.

From what class in Java Api I can call `info()`?

Also, I found such documentation: [https://www.elastic.co/guide/en/elasticsearch/client/java-api/6.1/java-admin-indices.html](https://www.elastic.co/guide/en/elasticsearch/client/java-api/6.1/java-admin-indices.html)  
But, I can't understand from what class an instance `client` is in the code `IndicesAdminClient indicesAdminClient = client.admin().indices();`  
I thought it was `HighLevelRestClient`. But in `HighLevelRestClient` there is no `admin()` method.  
May you explain this?

You are not looking at the right documentation. This one is for the Transport client. Have a look at info in high level rest client documentation

</div>

with such request `http://localhost:9200/_cluster/health?pretty` I have response:

```
    {
      "cluster_name" : "portal",
      "status" : "green",
      "timed_out" : false,
      "number_of_nodes" : 3,
      "number_of_data_nodes" : 2,
      "active_primary_shards" : 7,
      "active_shards" : 14,
      "relocating_shards" : 0,
      "initializing_shards" : 0,
      "unassigned_shards" : 0,
      "delayed_unassigned_shards" : 0,
      "number_of_pending_tasks" : 0,
      "number_of_in_flight_fetch" : 0,
      "task_max_waiting_in_queue_millis" : 0,
      "active_shards_percent_as_number" : 100.0
    }

```

And here I can see field `"status" : "green"`. With the help of `client.info()` I can only get `ClusterName, ClusterUuid, NodeName` and `Version`.  
How I can get `"status"` meaning through Java code?

found this one:

```
Map<String, String> parameters = singletonMap("wait_for_status", "green");
Response response = client.getLowLevelClient().performRequest("GET", "/_cluster/health", parameters); 

ClusterHealthStatus healthStatus;
try (InputStream is = response.getEntity().getContent()) { 
    Map<String, Object> map = XContentHelper.convertToMap(XContentType.JSON.xContent(), is, true); 
    healthStatus = ClusterHealthStatus.fromString((String) map.get("status")); 
}

if (healthStatus == ClusterHealthStatus.GREEN) {
    
}

```
