Aggregation of document

[AnaisH (Anaïs H)]

Hello,

I would like to concat different events in logstash/elasticsearch.
I receive this table

And I want to have this result in Kibana

But in Kibana I have this result

I think that it's necessary to set the .conf in logstash/bin, but I did'nt found an adapted plugin

Thank's !
