hi all
I have a socketappender setup in the elasticsearch logging.yml so that my ES instance sends slow search and slow index logs to my logstash instance via socketappender on port 9500.
I noticed that when I use an IP address for the socketappender hostName that it works ok, but when I try to use a server name or DNS name (i.e. "[myserver.mydomain.com](http://myserver.mydomain.com)") , it doesnt work; ie socketappender only accepts IP addresses (tho I have seen examples where it accepts "localhost")
the setup is on CentOS 7, and I am using ES 1.5.0 and logstash 1.5.2
is this a bug or by design? is there a workaround for this?
thanks in advance

note: reason I want to use DNS entries is that we are looking at hosting on AWS, and wanted to be able to set the hostName value to
1. a proper AWS DNS entry like "[logstash.mydomain.com](http://logstash.mydomain.com)" or
2. a load balancer name like "[internal-logstash-loadbalancer-xxxxxxxxxx.avzone.elb.amazonaws.com](http://internal-logstash-loadbalancer-xxxxxxxxxx.avzone.elb.amazonaws.com)"
so that we dont have to concern ourselves with changing IP addresses if/when the instance gets restarted or replaced
