OS version: CentOS 6.9 kibana version: 6.3.0 logstash version: 6.3.0 Add two logstash nodes, one node is normal, and the other show '0.0.0.0' ![image](https://us1.discourse-cdn.com/elastic/original/3X/f/a/fab0be1bedcc8aa61943333154fd8bfcb70860e2.png) How does kibana get the hostname of the operation system? Thanks!!! ---

I found that we can set a node name manually by set `node.name` in the config file `logstash.yml`. I followed this page: > **[logstash.yml | Logstash Reference \[7.11\] | Elastic](https://www.elastic.co/guide/en/logstash/current/logstash-settings-file.html)** Now it shows the specified node name, but I still wonder how kibana get the OS hostname. If I do not set node name manually, what happened? ---
