Hello everyone,  
I was able to configure ELK cluster and grok for postfix, now I have a problem in finding information.  
For every message sent I have 2 records similar to these:

- postfix\_queueid, postfix\_from
- postfix\_queueid, postfix\_to, postfix\_queueid, postfix\_status

How can I do to have a single line with:

postfix\_queueid, postfix\_from, postfix\_to, postfix\_status

Thank you

An [aggregate filter](https://www.elastic.co/guide/en/logstash/current/plugins-filters-aggregate.html) might work. Can you give actual examples of the events?
