In logstash.yml file, we have set node.name to a specific hostname explicitly. But the host field is displayed as "localhost".  
$HOSTNAME is set to a valid hostname.

If I sepecifically hardcode the hostname like below::

input {  
file {  
path =\> "/var/log/xyz/service.log"  
type =\> "xyz-daemon"  
add\_field =\> { "service-port" =\> "12345"  
"service-name" =\> "my-service"  
"host" =\> "abchost"  
}  
}

Then, both locahost and abchost are displayed as host.

Any suggestions how to ensure node.name is picked from logstash.yml file? We are running 5.4.1 version

> Hi. I am using udp input plugin to listen to syslog messages. The documentation says that the host field is the "The address which logstash will listen on". This is exacly what I need, but instead, host value is the IP address of the machine that sends the syslog message. Is that how it should be? Any way I can get the name of the LogStash machine no matter which plugin I am using? Thx in advance for your help.
