With a standard LB in front of an N-node cluster, what's the best URL in the ES API to check the health of a particular node (so as to know to remove it at least temporarily). There is the node info API: curl -XGET '[http://localhost:9200/\_nodes](http://localhost:9200/_nodes)' [http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/cluster-nodes-info.html](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/cluster-nodes-info.html) But that's returning node info for all the nodes in the cluster that localhost is a member of. I want something like /\_nodes/\_current. Or maybe the fact that a particular node can even process any GET request (e.g., [http://localhost:9200/\_cluster/health](http://localhost:9200/_cluster/health)) signifies that it is responsive enough and can take requests? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

If you just curl [http://IP:9200](http://IP:9200) you will get a response, if it's not 200 then chances are it's not part of the cluster and something is wrong.
