The access log does not contain the original host doing the request if the request goes thorugh the haproxy. Only the haproxy IP address is visible in the access log

11:35:32,027 INFO [org.jboss.openshift.valves.StdoutAccessLogValve] (http-0.0.0.0:8080-1) 10.1.0.1 - - [20/Jun/2017:11:35:31 +0000] "GET /kie-server/services/rest/server HTTP/1.1" 401 996

It might be useful to also print the X-Forwarded-For header, so that the original IP address is logged.
