We are working with a kafka broker version 0.9, meaning that logstash 5.4 is by default not compatible for the logstash-output-kafka.
1/ Which version do I need ? I saw on rubygems.org that version 4.0.6 is the most recent.
2/ How can I do this offline on a server with no direct internet connection ? What do I need to download ?
Hope you can help.
