Puppet Class: logstash::params

Inherited by:
logstash
Defined in:
manifests/params.pp

Overview

Class: logstash::params

This class exists to

  1. Declutter the default value assignment for class parameters.

  2. Manage internally used module variables in a central place.

Therefore, many operating system dependent differences (names, paths, …) are addressed in here.

Parameters

This class does not provide any parameters.

Examples

This class is not intended to be used directly.
