Kibana unable to connect to local Elasticsearch: plugin:elasticsearch: Service Unavailable

(Jason) #1

I have an instance of Kibana that I am trying to connect to a Elasticsearch cluster. The Kibana server has a non-master and non-data instance of Elasticsearch configured as connected to the cluster. Here is the output of my ES cluster health:

  "cluster_name" : "Elasticsearch-Cluster-1",
  "status" : "green",
  "timed_out" : false,
  "number_of_nodes" : 4,
  "number_of_data_nodes" : 3,
  "active_primary_shards" : 2,
  "active_shards" : 4,
  "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

As you can see there are 4 nodes, only 3 of them are data nodes. The fourth is my Kibana server, so it is connecting to the cluster just fine. In all four nodes of the ES configuration I have bind address setup as: _non_loopback:ipv4_

In the Kibana configuration I have elasticsearch.url setup as the IP of my Kibana server:

elasticsearch.url: ""

Prior to changing the above setting to what you see I was getting an error saying "Unable to connect to http://localhost:9200". Now the error just says plugin:elasticsearch Service Unavailable

Its not a firewall issue as all 4 node in the cluster have 9200/TCP and 9300/TCP open. I have confirmed this with an NMAP scan.

Anyone have any thoughts?

If I point Kibana to one of the other 3 ES nodes in the cluster everything works perfectly. I am not sure why Kibana is unable to connect to the ES that is configured locally.

Anyone have any input to offer? I really need some help with this. Thanks!
