Hello! I have been trying to figure out why my logstash always reuses localhost for healthchecks, even if not defined ANYWHERE.

Here is some snippets from the error log (full gist here: [https://www.irccloud.com/pastebin/raw/GGogttEL](https://www.irccloud.com/pastebin/raw/GGogttEL))

```

```

It connects to the remote Elastic host, but the logstash service restarts every 10 seconds, with no errors except the one above, configtests passes, and i also tried to start it from cmdline definining both path.settings and -f to make sure it loads the correct files.

Logstash.yaml:

```
node.name: XXX-LOGSTASH
path.data: /var/lib/logstash
path.config: /usr/share/logstash/conf.d
path.logs: /var/log/logstash
    
xpack:
  monitoring:
    enabled: true
    elasticsearch:
      url:
      - REMOTEHOST:9200
      username: "XXX"
      password: "XXXX"

modules:
- name: arcsight
  arcsight.var.inputs: smartconnector
  arcsight.var.input.smartconnector.port: 5000
  arcsight.var.elasticsearch.hosts: REMOTEHOST:9200
  arcsight.var.elasticsearch.username: XXX
  arcsight.var.elasticsearch.password: XXX
  arcsight.var.kibana.host: REMOTEHOST:5601
  arcsight.var.kibana.username: XXX
  arcsight.var.kibana.password: XXX

```

sample.conf:

```
input { stdin { } }
output {
  elasticsearch {
        hosts => ["REMOTEHOST:9200"]
        user => elastic
        password => XXX
  }
}
```
