I have installed a logstash plugin logstash-input-jms. I build the .gem file and used the bin/plugin install command. It shows it installed successfully, yet when i run bin/plugin list, it is not listed. I tried with both 1.5.0 and the latest 1.5.1 I have searched extensively but documentation here is limited for both this plugin and this issue. ---

I am facing the similar issue with the example which is given in the input plugin page. ([https://www.elastic.co/guide/en/logstash/current/\_how\_to\_write\_a\_logstash\_input\_plugin.html](https://www.elastic.co/guide/en/logstash/current/_how_to_write_a_logstash_input_plugin.html)) The only renamed the plugin's name from example to example2, even in the gemspec etc. I am trying to figure how set the namespace, which is expected in line#131 of plugin.rb of logstash-1.5.1/vendor/bundle/jruby/1.9/gems/logstash-core-1.5.1-java/lib/logstash **When I debug it I get the following error message** : bin/logstash --debug -e 'input { example2{} } output {stdout { codec =\> rubydebug }}' Compiled pipeline code: @inputs = [] @filters = [] @outputs = [] @periodic\_flushers = [] @shutdown\_flushers = [] ``` @input_example2_1 = plugin("input", "example2") @inputs << @input_example2_1 @output_stdout_2 = plugin("output", "stdout", LogStash::Util.hash_merge_many({ "codec" => ("rubydebug") })) @outputs << @output_stdout_2 ``` def filter\_func(event) events = [event] @logger.debug? && @logger.debug("filter received", :event =\> event.to\_hash) events end def output\_func(event) @logger.debug? && @logger.debug("output received", :event =\> event.to\_hash) @output\_stdout\_2.handle(event) end {:level=\>:debug, :file=\>"logstash/pipeline.rb", :line=\>"28", :method=\>"initialize"} Plugin not defined in namespace, checking for plugin file {:type=\>"input", :name=\>"example2", :path=\>"logstash/inputs/example2", :level=\>:debug, :file=\>"logstash/plugin.rb", :line=\>"133", :method=\>"lookup"} The error reported is: Couldn't find any input plugin named 'example2'.

try the following format: |-- lib | -- logstash | -----inputs | ------- example2.rb |-- logstash-input-example2-0.1.0.gem |-- logstash-input-example2.gemspec |-- spec |----- logstash |--------- inputs |------------- example2.rb Fix the gemspec also. ---

I had the same issue. I created a plugin and installed it with 'bin/plugin install --no-verify .gem', but it wouldn't show up when doing 'plugin list'. My problem was I did not include the .gemspec file in the Gem::Specification, s.files array. This GitHub issue below tipped me to the problem. Installing empty plugins #3444 > ---

Similar to @whyapenny, I have installed a custom logstash output plugin. I build the .gem and specified the new plugin .gem path in the Gemfile and then tried **bin/plugin install --no-verify**. It shows it installed successfully, yet when i run **bin/plugin list** , it is not listed. I tried with both 1.5.0 and the latest 1.5.1. I have seen similar issues posted but the suggested solution is not working. When I run with debug on, it explicitly says development group plugins were not included. What do I have to do to get a development group plugin installed properly? ---

Found solution? I'm having the same issue today. I'm using logstash-1.5.0 and used the latest log stash-filter-example from GitHub today. ---

I had a similar issue as well, where `bin/plugin list` did not show my plugin. But, when I start logstash with my output plugin included in the config, it works just fine. ---

Had similar problems this week where I was building 'empty' plugins. If it could be helpful, this is how I build plugins without messing up my machine: Install docker if not done yet. Build following `Dockerfile` (`docker build -t sbeaupre/jruby .`): > FROM jruby:1.7 > RUN apt-get update > && apt-get install -y git > && gem install bundler > && bundle install Then write your own plugin or clone a plugin from github (Do not just download a zip from github! For some reason, some/most plugins have dependencies on git during the build), eg: ``` git clone -b v1.0.7 https://github.com/logstash-plugins/logstash-output-elasticsearch.git ``` In the root plugin folder, execute following command: ``` docker run -it --rm --name build-it -v "$PWD":/usr/src -w /usr/src sbeaupre/jruby bundle install && gem build logstash-output-elasticsearch.gemspec ``` And you get the gem file in the root folder of the plugin. Main disadvantage is that the `bundle install` takes some time, but it is a flexible setup. I am also using docker to test different ELK configurations. hth, Sven ---

I still have not had success with this. I have reverted back to logstash 1.4.2 and kibana 3. ---

@fh8510 I added '\*.gemspec' to the s.files array: s.files = Dir['lib/logstash/outputs/_.rb', 'spec/\*\*/_.rb', '\*.gemspec'] but the plugin is still not listed in the output of bin/plugin list even though it said it installed successfully. ---

Yes. I have also experienced this issue, posted about it asking for help - even offered a bounty! Nothing. Nadda. Zippo. Zilch. The inability to develop, install and use my own plugins is destroying my commitment to Logstash. Before the new plugin manager it was a walk in the park ☹ ---

Hi Do we have any solution for this, i am facing this problem with file input plugin? I am getting this error `Plugin not defined in namespace, checking for plugin file` Here is my config file, basically i am loading csv file in ES ``` input { file { sincedb_path => "E:/sincedbfile/sincedb_file1.txt" path => "E:/sincedbfile/abc.csv" type=> "quality" start_position => "beginning" } } filter { csv { separator => "," columns => ["QualityEvent" , "EventNumber"] } } output { stdout { codec => rubydebug } elasticsearch { action => "index" hosts => "127.0.0.1:9200" index => "abcde" } } ``` ---

There is a variable in your plugin's main class with name - config\_name. Make sure that this is not set to empty string and has a name same as your plugin. In case your plugin is logstash-input-xyz then config\_name "xyz" Hope this helps 🙂 ---
