my bad ,my bad, my bad.......sorry for wasting your time @jsoriano all these time i was checking whether data is flowing in or not by just clicking the beat.hostname on the lefthand side and checking how many hosts are there.it was showing only one.
After your question only i have searched for beat.hostname in the query field and got the output, yeah i'm getting all the documents flowing into elasticsearch.
Thank you very much for your patience and proper questions asked.
btw here is the screenshot of connection output
Thanks
