You can query the Eleasticsearch API directly to get an overview of all connected nodes. For example, login to 192.168.1.100 and execute this: curl -XGET ' http://192.168.1.100:9200/_cluster/state/nodes?pretty'
You should see the Graylog server instance as one node + three real Elasticsearch nodes. In total four.
