Logstash Plugin

Fork

This is a fork of the original Logstash Mail Plugin. It is published as logstash-output-email2.

This is a plugin for Logstash.

It is fully free and fully open source. The license is Apache 2.0, meaning you are pretty much free to use it however you want in whatever way.

Documentation

Logstash provides infrastructure to automatically generate documentation for this plugin. We use the asciidoc format to write documentation so any comments in the source code will be first converted into asciidoc and then into html. All plugin documentation are placed under one central location.

For formatting code or config example, you can use the asciidoc [source,ruby] directive
For more asciidoc formatting tips, see the excellent reference here https://github.com/elastic/docs#asciidoc-guide

Developing

1. Plugin Developement and Testing

Code

To get started, you'll need JRuby with the Bundler gem installed.
Create a new plugin or clone and existing from the GitHub logstash-plugins organization. We also provide example plugins.
Install dependencies
```
bundle install
```

Test

Update your dependencies

bundle install

Run tests

bundle exec rspec

2. Running your unpublished Plugin in Logstash

2.1 Run in a local Logstash clone

Edit Logstash Gemfile and add the local plugin path, for example: ruby gem "logstash-filter-awesome", :path => "/your/local/logstash-filter-awesome"
Install plugin ```sh # Logstash 2.3 and higher bin/logstash-plugin install --no-verify

Prior to Logstash 2.3

bin/plugin install --no-verify

- Run Logstash with your plugin
```sh
bin/logstash -e 'filter {awesome {}}'

At this point any modifications to the plugin code will be applied to this local Logstash setup. After modifying the plugin, simply rerun Logstash.

2.2 Run in an installed Logstash

You can use the same 2.1 method to run your plugin in an installed Logstash by editing its Gemfile and pointing the :path to your local plugin development directory or you can build the gem and install it using:

Build your plugin gem sh gem build logstash-filter-awesome.gemspec
Install the plugin from the Logstash home ```sh # Logstash 2.3 and higher bin/logstash-plugin install --no-verify

Prior to Logstash 2.3

bin/plugin install --no-verify

- Start Logstash and proceed to test the plugin

## Contributing

All contributions are welcome: ideas, patches, documentation, bug reports, complaints, and even something you drew up on a napkin.

Programming is not a required skill. Whatever you've seen about open source and maintainers or community members  saying "send patches or die" - you will not see that here.

It is more important to the community that you are able to contribute.
