The feedback message is  
{ "message":"xxx",  
"host":"da30faafb1s4e2d2"  
}

the host is a hashed value  
Is there any way that I can get the ip address or domain name in the host field?  
How can I configure it?

Please tell us more about your setup. Are you by any chance running Logstash in a Docker container?

Yes. I am running logstash in a docker container. And I've found the way to add a customized hostname.  
FYI, just run the container with docker run --hostname=yourhostname logstash  
Thanks
