ok here is one more info if i run below
curl -XGET localhost:9200/logstash-*/_field_stats?fields=@timestamp
i get below
{"_shards":{"total":40,"successful":40,"failed":0},"indices":{"_all":{"fields":{"@timestamp":{"max_doc":9114,"doc_count":9114,"density":100,"sum_doc_freq":36456,"sum_total_term_freq":-1,"min_value":1470571575000,"min_value_as_string":"2016-08-07T12:06:15.000Z","max_value":1471190833000,"max_value_as_string":"2016-08-14T16:07:13.000Z"}}}}}
as you can see the index is there only till 14th Aug and its not generating now. At this time logstash / elasticsearch/ kibana all running fine and i cant see any error. Whats wrong in here any more inputs ?.
Should i remove all three and do it again ?
