logstashCollector is not reporting accessLog

Running Liberty Server WebSphere Application Server

with this config

I’m getting this message in the startup :
[WARNING ] TRAS0118W: Health Center agent was not found, so JVM monitoring and diagnostic information will not be available.

Using logstash 2.4.1, elasticsearch-2.4.4, kibana-4.6.4-windows-x86 I’m only getting message type of records in Kibana. I was expecting http access log entries as specified in http://www.ibm.com/support/knowledgecenter/SSEQTP_8.5.5/com.ibm.websphere.wlp.doc/ae/cwlp_analytics_collectors.html

How can debug this, or is it more config necessary ?
