Duplication of data using the aggregate plugin


(Scopy) #1

The first time we used logstash to process data today, there was a problem of data duplication or loss.This is logstash's bug or I've got a mistake?
And my logstash.conf is:

input {
stdin {}

I would be grateful if anyone could give me some advice.
