As long as you use the HTTP protocol you can use Logstash 1.5.5 with any ES release currently in existence. See [https://www.elastic.co/support/matrix](https://www.elastic.co/support/matrix).

Is the HTTP On by default ? When I use stdout I der a fine readout on the console but when I send it to Es I der weird errors ( I'll c/p ) them here when I can. Thought the 1.5.5 log stash was not compatable with Es 2.2

HTTP is default only for Logstash 2.0 and later.
