I installed logstash 1.5.2 on Centos 6.5 VM (test environment). My previous used version was Logstash 1.4.2 and I kept the same configuration files used with previous version. When I launch logstash I get the following error: **LoadError: no such file to load -- restclient** **require at org/jruby/RubyKernel.java:1072** **require at /application/nfmoss/vendors/logstash/vendor/bundle/jruby/1.9/gems/polyglot-0.3.5/lib/polyglot.rb:65** **register at (ruby filter init):5** **eval at org/jruby/RubyKernel.java:1111** **register at /application/nfmoss/vendors/logstash/vendor/bundle/jruby/1.9/gems/logstash-filter-ruby-1.0.0/lib/logstash/filters/ruby.rb:29** **each at org/jruby/RubyArray.java:1613** **start\_filters at /application/nfmoss/vendors/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-1.5.2.2-java/lib/logstash/pipeline.rb:154** **run at /application/nfmoss/vendors/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-1.5.2.2-java/lib/logstash/pipeline.rb:81** **execute at /application/nfmoss/vendors/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-1.5.2.2-java/lib/logstash/agent.rb:150** **run at /application/nfmoss/vendors/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-1.5.2.2-java/lib/logstash/runner.rb:91** **call at org/jruby/RubyProc.java:271** **run at /application/nfmoss/vendors/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-1.5.2.2-java/lib/logstash/runner.rb:96** **call at org/jruby/RubyProc.java:271** **initialize at /application/nfmoss/vendors/logstash/vendor/bundle/jruby/1.9/gems/stud-0.0.20/lib/stud/task.rb:12** I use a ruby logstash filter for my use case and I need the rest-client gem, but this gem isn't present under my installation path /application/nfmoss/vendors/logstash/vendor/bundle/jruby/1.9/gems/ So I tried to install the rest-client gem with the command "sudo gem install rest-client" (after execution of command "sudo yum install rubygems"), but I get another error: **Building native extensions.

My question is: is there a command to install the rest-client gem on top of the Logstash core pipeline? If I try this installation using the command $LS\_HOME/bin/plugin install rest-client, rightly, I have the following response: Validating rest-client Found rest-client (1.8.0), but was for platforms x86-mingw32 ,x64-mingw32 ,x86-mswin32 rest-client is not a Logstash plugin ERROR: Installation aborted, verification failed for rest-client ---

How did you install LS? ---

I don't believe there is a rest-client plugin for LS. ---

No, indeed, I talk about the rest-client gem not the rest-client plugin. The LS\_HOME/logstash-1.5.2/vendor/bundle/jruby/1.9/gems folder is created when I unzip the logstash package on my installation path. Under this folder I can see a list of ruby gems used by logstash with a list of logstash plugins. Now, the folder LS\_HOME/logstash-1.4.2/vendor/bundle/jruby/1.9/gems, related to 1.4.2 version, includes the rest-client-1.6.7 ruby gem whereas the folder LS\_HOME/logstash-1.5.2/vendor/bundle/jruby/1.9/gems doesn't include any ruby rest-client gem. My ruby filter requires the rest-client gem but logstash crashes at starting for the error **LoadError: no such file to load -- rest-clien** t. On logstash github page [https://github.com/elastic/logstash](https://github.com/elastic/logstash) I can see the Gemfile.jruby-1.9.lock file where there is a ruby gems list including the rest-client (1.8.0) gem with his dependencies, but after package installation this ruby gem isn't present under LS\_HOME/logstash-1.5.2/vendor/bundle/jruby/1.9/gems folder. Maybe, something in package building is wrong. I'd like to know if there is some work around to solve this problem. Thanks. ---
