Service Discovery Plugins

Fluentd has nine (9) types of plugins:
​Input​
​Parser​
​Filter​
​Output​
​Formatter​
​Storage​
​Service Discovery​
​Buffer​
​Metrics​
This article gives an overview of the Service Discovery Plugin.
Overview
Some plugins support <service_discovery> (e.g. out_forward). Sometimes, the service discovery for an output plugin does not meet one's needs. Fluentd has a pluggable system called Service Discovery that lets the user extend and reuse custom output service discovery.
How To Use
Here is a simple example to update target by reading file (/etc/fluentd/sd.yaml) with out_forward and service_discovery:
<source>
  @type forward
​
  <service_discovery>
    @type file
    path "/etc/fluentd/sd.yaml"
  </service_discovery>
</source>
