Hi guys!

New user here, I'm currently finding a tonne of this in my `elasticsearch_server.json` log, and I can't find out where it is:

```

I'm trying to figure out which host this comes from, is it really the elastichost itself? And why? I have xpack enabled, and we are running kibana/filebeat and it seems to work, so I'm not sure which host could be the culprit, so I want to know how to find it out.

Here is the elastic config:

```auto
> node.name: node-1
> path.data: /var/lib/elasticsearch
> path.logs: /var/log/elasticsearch
> cluster.initial_master_nodes: node-1
> network.host: 0.0.0.0
> xpack.security.enabled: true
> xpack.security.authc.api_key.enabled: true
> xpack.security.http.ssl.enabled: true
> xpack.security.transport.ssl.enabled: true
> xpack.security.http.ssl.key: /etc/elasticsearch/certs/foo.key
> xpack.security.http.ssl.certificate: /etc/elasticsearch/certs/foo.crt
> xpack.security.transport.ssl.key: /etc/elasticsearch/certs/foo.key
> xpack.security.transport.ssl.certificate: /etc/elasticsearch/certs/foo.crt

```
