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.
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.
You can use the built-in plugin tool of Logstash to install the filter:
$LS_HOME/bin/logstash-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/logstash-plugin install logstash-filter-rest-0.1.0.gem
Add the following inside the filter section of your logstash configuration:
filter {
rest {
request => {
url => "http://example.com" # string (required, with field reference: "http://example.com?id=%{id}" or params, if defined)
method => "post" # string (optional, default = "get")
headers => { # hash (optional)
"key1" => "value1"
"key2" => "value2"
}
auth => {
user => "AzureDiamond"
password => "hunter2"
}
params => { # hash (optional, available for method => "get" and "post"; if post it will be transformed into body hash and posted as json)
"key1" => "value1"
"key2" => "value2"
"key3" => "%{somefield}" # sprintf is used implicitly
}
}
json => true # boolean (optional, default = true)
target => "my_key" # string (mandatory, no default)
fallback => { # hash describing a default in case of error
"key1" => "value1"
"key2" => "value2"
}
}
}Print plugin version:

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.
