Shipping gzip files and unzipping them through logstash

I am using all curent versions of the ELK stack and shipping with log-courier. I am shipping .gz files and they are being shipped but not uncompressed while using the gz_lines codec.

input {
courier {
port => 9020
type => "gzip"
ssl_certificate => "/etc/pki/tls/certs/logstash-forwarder.crt"
ssl_key => "/etc/pki/tls/private/logstash-forwarder.key"
codec => gzip_lines

this is my current input .. Any idea on how to get this to work?


anyone have an idea on how to do this? this is a blocker on my end as of now.
