Hi,

I'm currently setting up Logstash and I'm wondering which Elasticsearch nodes I should add into the "hosts" array in the elasticsearch output configuration.

```
elasticsearch {
  hosts => ...
  ...

```

In my environment I have a "Hot/Warm" architecture with the following node types:

> 3x Master Nodes  
> 6x Data Nodes (3 Hot / 3 Warm)  
> 3x Coordinator only nodes

From the [documentation](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-elasticsearch.html#plugins-outputs-elasticsearch-hosts) I can see it is not advisable to send to the "Master" nodes, however I am unsure which remaining hosts should be added to the hosts array inside of the output configuration file. My gut feelings would be that I should add the "Hot" data nodes only?

As always, any advice or suggestions welcome 🙂

Yes, listing just the hot nodes sounds reasonable.
