Logstash node name show '' on kibana

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 ''

How does kibana get the hostname of the operation system?


I found that we can set a node name manually by set node.name in the config file logstash.yml.

I followed this page:

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?
