Hi,

Actually i use a personal java program to take nginx log protobuf format from kafka , then transform it into avro format , then resend it to another topic in kafka and then use logstash to take it and inject it in elastic.

do u know a way to do it directly from logstash , i don't find it ?

Tx Laurent
