Overview

This module manages the Carbon daemons.

Module Description

This module installs the Carbon packages, configures the carbon, relay, and aggregator daemons and runs them. It currently leverages systemd to support running multiple instances of each. It also manages the various rules and lists supported by each.

Setup

If running on Puppet 3.x you will need to have the future parser enabled. On RHEL/CentOS platforms you will need to enable the EPEL repository first.

What carbon affects

  • The package(s) providing the Carbon software.
  • The various /etc/carbon/*.conf configuration files.
  • The systemd unit file for each daemon instance.

Beginning with carbon

include ::carbon

Limitations

This module leverages systemd to create multiple instances of the three daemons.

This module has been built on and tested against Puppet 3.0 and higher.

The module has been tested on:

  • RedHat/CentOS Enterprise Linux 7

Testing on other platforms has been light and cannot be guaranteed.
