In `kibana.yml` , I have a setting I'm not sure about:

```auto
# The URL of the Elasticsearch instance to use for all your queries.
elasticsearch.hosts: "http://localhost:9400"

```

Which is pointing to a coordinating node running on the same host as Kibana - is this bottlenecking my setup? I have multiple coordinating nodes in this cluster, should I add them to `elasticsearch.hosts`?  
When I have cross-cluster search enabled;

- is `elasticsearch.hosts` just ignored in favor of the Seeds?
  - Otherwise, how does the request flow from Kibana to the next cluster?
  - As I'm supposed to only put local-cluster node names in my `elasticsearch.hosts`, does a request for data from another cluster get routed from the local-cluster coordinating nodes to the remote cluster nodes?

- Since I've got Kibana running in one cluster, should I still add that as a remote cluster?
  - e.g. index patterns would look like: `local_cluster1:logstash-*,remote_cluster2:logstash-*`
  - Or should I leave the kibana local cluster out of the Remote Clusters?
    - e.g. index patterns would look like: `logstash-*,remote_cluster2:logstash-*`

Hi @seth.yes,

thanks for your question.

> Which is pointing to a coordinating node running on the same host as Kibana - is this bottlenecking my setup? I have multiple coordinating nodes in this cluster, should I add them to `elasticsearch.hosts` ?

Yes it makes sense to add other coordinating nodes to the setting - then Kibana won't be down when this single elasticsearch host goes down because it can still query other nodes.

> is `elasticsearch.hosts` just ignored in favor of the Seeds?

Cross cluster search always hits the local cluster first, Kibana does not query remote clusters directly. The [elasticsearch documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-cross-cluster-search.html) nicely documents the data flow - Kibana acts as the client in this scenario.

> Since I've got Kibana running in one cluster, should I still add that as a remote cluster?

No, you can leave the local cluster out of remote clusters, `logstash-*,remote_cluster2:logstash-*` is the right configuration here.

Thanks! You answered all of my questions perfectly.
