Hello and welcome!

You can find documentation on the sniffer [here](https://www.elastic.co/docs/reference/elasticsearch/clients/java/transport/rest-client/sniffer). It’s not part of the `elasticsearch-java` dependency, it’s from:

```auto
<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifactId>elasticsearch-rest-client-sniffer</artifactId>
    <version>8.19.11</version>
</dependency>

```
