I have configured Fluentd on windows server (WIN 2012) and trying to tail customized application logs (which is present in C:/opt/td-agent/application.log) to elastic search. Each time when i configure and start the agent i could see that "fluentd worker is now running worker=0" message in Kibana but not my application logs. config details given below, please help to fix the issue.
