hi warkolm i am running logstash 2.2.0 in debian. i think following logs might be useful which i got by running in logstash: (debug mode) {:timestamp=\>"2016-03-02T11:38:06.977000+0530", :message=\>"config LogStash::Codecs::RubyDebug/@metadata = false", :level=\>:debug, :file= > "logstash/config/mixin.rb", :line=\>"122", :method=\>"config\_init"} > The error reported is: > undefined method `on_load' for ActiveSupport:Module /home/opens/elk/logstash-2.2.2/vendor/bundle/jruby/1.9/gems/awesome_print-1.6.1/lib/awesome_print.rb:29:in `(root)' > org/jruby/RubyKernel.java:1040:in `require' /home/opens/elk/logstash-2.2.2/vendor/bundle/jruby/1.9/gems/polyglot-0.3.5/lib/polyglot.rb:65:in `require' > /home/opens/elk/logstash-2.2.2/vendor/bundle/jruby/1.9/gems/logstash-codec-rubydebug-2.0.5/lib/logstash/codecs/rubydebug.rb:1:in `(root) ' /home/opens/elk/logstash-2.2.2/vendor/bundle/jruby/1.9/gems/logstash-codec-rubydebug-2.0.5/lib/logstash/codecs/rubydebug.rb:18:in `regis > ter' > /home/opens/elk/logstash-2.2.2/vendor/bundle/jruby/1.9/gems/logstash-core-2.2.2-java/lib/logstash/config/mixin.rb:370:in `validate_value ' /home/opens/elk/logstash-2.2.2/vendor/bundle/jruby/1.9/gems/logstash-core-2.2.2-java/lib/logstash/codecs/base.rb:15:in `initialize' > org/jruby/RubyArray.java:1613:in `each' /home/opens/elk/logstash-2.2.2/vendor/bundle/jruby/1.9/gems/logstash-core-2.2.2-java/lib/logstash/config/mixin.rb:311:in `validate\_check > \_parameter\_values' > org/jruby/RubyHash.java:1342:in `each' /home/opens/elk/logstash-2.2.2/vendor/bundle/jruby/1.9/gems/logstash-core-2.2.2-java/lib/logstash/config/mixin.rb:306:in `validate\_check > \_parameter\_values' > /home/opens/elk/logstash-2.2.2/vendor/bundle/jruby/1.9/gems/logstash-core-2.2.2-java/lib/logstash/config/mixin.rb:305:in `validate_check _parameter_values' /home/opens/elk/logstash-2.2.2/vendor/bundle/jruby/1.9/gems/logstash-core-2.2.2-java/lib/logstash/config/mixin.rb:220:in `validate' > /home/opens/elk/logstash-2.2.2/vendor/bundle/jruby/1.9/gems/logstash-core-2.2.2-java/lib/logstash/config/mixin.rb:102:in `config_init' /home/opens/elk/logstash-2.2.2/vendor/bundle/jruby/1.9/gems/logstash-core-2.2.2-java/lib/logstash/outputs/base.rb:63:in `initialize' > /home/opens/elk/logstash-2.2.2/vendor/bundle/jruby/1.9/gems/logstash-core-2.2.2-java/lib/logstash/output\_delegator.rb:28:in `initialize' /home/opens/elk/logstash-2.2.2/vendor/bundle/jruby/1.9/gems/logstash-core-2.2.2-java/lib/logstash/pipeline.rb:403:in `plugin' > org/jruby/RubyKernel.java:1079:in `eval' (eval):158:in `initialize' > /home/opens/elk/logstash-2.2.2/vendor/bundle/jruby/1.9/gems/logstash-core-2.2.2-java/lib/logstash/pipeline.rb:57:in `initialize' /home/opens/elk/logstash-2.2.2/vendor/bundle/jruby/1.9/gems/logstash-core-2.2.2-java/lib/logstash/agent.rb:172:in `execute' > org/jruby/RubyProc.java:281:in `call' /home/opens/elk/logstash-2.2.2/vendor/bundle/jruby/1.9/gems/logstash-core-2.2.2-java/lib/logstash/runner.rb:90:in `run' > org/jruby/RubyProc.java:281:in `call' /home/opens/elk/logstash-2.2.2/vendor/bundle/jruby/1.9/gems/logstash-core-2.2.2-java/lib/logstash/runner.rb:95:in `run' Suggest some solution to solve this. ---
