I've read [Reduce duplicate or similar log entries](https://discuss.elastic.co/t/reduce-duplicate-or-similar-log-entries/29029)
how can i Reduce duplicate or similar log entries with collate?
I used it like that:
collate {
interval =\> "1s"
order =\> "ascending"
}
and my logs were collected - but the similiar logs were not removed.
I want to removed and dont index similiar logs.
Sometimes i have very many similiar logs with different time. How can i reduce count of them and dont index most of them?
They have different "\_id".
I am using Kibana 3 with Logstash 2.1 and ES 1.4.2
