Hello,
The latest puppet-logstash module on Puppet forge is version 0.5.1 and was released May 15th 2014. The most recent version of Logstash "officially" supported by the module is 1.4.1, and the most recent version of Logstash is 2.2.0.
Is this module still being worked on? Has anybody successfully used it with one of the Logstash 2.x releases?
