REST Filter for Logstash

Logstash REST Filter

This is a filter 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

This logstash filter provides an easy way to access RESTful Resources within logstash. It can be used to post data to a REST API or to gather data and save it in your log file.

Usage

1. Installation

You can use the built-in plugin tool of Logstash to install the filter:

$LS_HOME/bin/plugin install logstash-filter-rest

Or you can build it yourself:

git clone https://github.com/lucashenning/logstash-filter-rest.git
bundle install
gem build logstash-filter-rest.gemspec
$LS_HOME/bin/plugin install logstash-filter-rest-0.1.0.gem

2. Filter Configuration

Add the following inside the filter section of your logstash configuration:

rest {
  url => "http://example.com"       # string (required, with field reference: "http://example.com?id=%{id}")
  json => true                      # boolean (optional, default = false)
  method => "post"                  # string (optional, default = "get")
  sprintf => true                   # boolean (optional, default = false, set this to true if you want to use field references in url, header or params)
  header => {                       # hash (optional)
    "key1" => "value1"
    "key2" => "value2"
    "key3" => "%{somefield}"        # Please set sprintf to true if you want to use field references
  }
  params => {                       # hash (optional, only available for method => "post")
    "key1" => "value1"
    "key2" => "value2"
    "key3" => "%{somefield}"        # Please set sprintf to true if you want to use field references
  }
  response_key => "my_key"          # string (optional, default = "rest_response")
}

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.
