After getting frustrated with very very simple configuration ([Elastic node hangs (i think)](https://discuss.elastic.co/t/elastic-node-hangs-i-think/118714/4) ) i installed 6.2 version of ES , Kibana and Logstash.
ES is running in debug mode.
Logstash has debug on for following.
"logstash.outputs.elasticsearch" : "DEBUG",
I start log stash and there is no debug entries for reading my web server logs and sending event to ES.
but if i stop 6.2 version fo logstash and start 6.1 i see logs sending events to my ES.
just dont know what am i doing wrong 🙂

reinstalled everything (ES , logstash and kibana). Now i m back to my origional issue which was reported in [Elastic node hangs (i think)](https://discuss.elastic.co/t/elastic-node-hangs-i-think/118714/4). So i have no idea what am i doing wrong ( There is nothing in grok failure logs , my logstash has debug on and has lines of my http server log entries. but in ES it just doesnt show up after some time.
any body experience this ?

Did you set that? If so it's going to mean events (documents) will not show up even though they are being received by Elasticsearch. It needs to be a positive number.

so positive number is represented in # of seconds ?
