Hi,

I am using ES 7.10.2

I have come across Index Stats API in ES documentation. Also in Java Lib there is class available named

I did come across `NodeClient`, so I am trying to fetch index stats as below :

```auto
NodeClient nodeClient = new NodeClient(Settings.EMPTY, new ThreadPool(Settings.EMPTY));
				IndicesStatsRequestBuilder indicesStatsRequestBuilder = nodeClient.admin()
						.indices()
						.prepareStats("indexNameHere");
				IndicesStatsResponse indicesStatsResponse = indicesStatsRequestBuilder.get();
				System.out.println("indicesStatsResponse = " + indicesStatsResponse);

```

But I am getting `NodeClient has not been initialized` exception, what I am doing wrong ? or am I missing any steps ?

Any help is much appreciated:)

Hi @Nishikant_Tayade .

If you are not successful with the IndicesStatsRequest you can also do it as follows:

```
 Request request = new Request("GET", "/index_name/_stats");
 var response = client.getLowLevelClient().performRequest(request);
 System.out.println(EntityUtils.toString(response.getEntity()));
```

@RabBit_BR Thanks for reaching out !! As I can't use lowlevelclient, I did found another way to, using `NodeClient` actaully, I have updated my question.
