I am trying to install output plugin using below command but it has failed saying there is no connection. But I tried to download and able to download using wget. I have extracted the download .gz file and it is a data file. How to install with the downloaded file manually. I believe it could be possible to install using local downloaded file. If this is not possible, what other options to debug and install the output plugin. Please advise me. ./logstash-plugin install logstash-output-email Validating logstash-output-email Unable to download data from [https://rubygems.org](https://rubygems.org) - Errno::ECONNREFUSED: Connection refused - Connection refused ([https://api.rubygems.org/latest\_specs.4.8.gz](https://api.rubygems.org/latest_specs.4.8.gz)) ERROR: Installation aborted, verification failed for logstash-output-email ---

Perhaps you need to configure logstash-plugin to use your HTTP proxy? ---

I found these export options. export http\_proxy=http://proxy.server:3128 export https\_proxy=http://proxy.server:3128 export JRUBY\_OPTS="-J-Dhttp.proxyHost=proxy.host -J-Dhttp.proxyPort=3128" Is the port 3128 is the default one or I have get this from the administrator ? Is there any other options to install manually ? ---

Hi Magnusbaeck @ My logstash process is spawning new process id every few seconds and my logstash is not started properly. This behavior has started since I tried to install the output email plugin. From the /var/log/messages/logstash-stderr.log file I see the following error message. Any thing that I can do to resolve this error ? this is the working system. Bundler::GemNotFound: Could not find gem 'logstash-output-email (\>= 0) java' in any of the gem sources listed in your Gemfile or installed on this machine. verify\_gemfile\_dependencies\_are\_found! at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler/resolver.rb:328 each at org/jruby/RubyArray.java:1613 verify\_gemfile\_dependencies\_are\_found! at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler/resolver.rb:307 start at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler/resolver.rb:199 resolve at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler/resolver.rb:182 resolve at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler/definition.rb:192 specs at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler/definition.rb:132 specs\_for at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler/definition.rb:177 requested\_specs at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler/definition.rb:166 requested\_specs at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler/environment.rb:18 setup at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler/runtime.rb:13 setup at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler.rb:122 setup! at /usr/share/logstash/lib/bootstrap/bundler.rb:64 (root) at /usr/share/logstash/lib/bootstrap/environment.rb:64 Bundler::GemNotFound: Could not find gem 'logstash-output-email (\>= 0) java' in any of the gem sources listed in your Gemfile or installed on this machine. verify\_gemfile\_dependencies\_are\_found! at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler/resolver.rb:328 each at org/jruby/RubyArray.java:1613 verify\_gemfile\_dependencies\_are\_found! at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler/resolver.rb:307 start at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler/resolver.rb:199 resolve at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler/resolver.rb:182 resolve at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler/definition.rb:192 specs at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler/definition.rb:132 specs\_for at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler/definition.rb:177 requested\_specs at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler/definition.rb:166 requested\_specs at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler/environment.rb:18 setup at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler/runtime.rb:13 setup at /usr/share/logstash/vendor/bundle/jruby/1.9/gems/bundler-1.9.10/lib/bundler.rb:122 setup! at /usr/share/logstash/lib/bootstrap/bundler.rb:64 (root) at /usr/share/logstash/lib/bootstrap/environment.rb:64 Please advice. ---

created a new issue since http\_proxy settings are required for this issue and errors state it is due to Bundler::GemNotFound and it is new issue. Thanks Magnus. ---
