Setup

Setup Requirements

puppet-telegraf requires only the wget module when the parameter install_from_repository is set to false. Furthermore the stdlib module is required.

Beginning with telegraf

Include the class and set the necessary Telegraf and InfluxDB parameters.

class { '::telegraf':
    version                   => '0.2.4',
    install_from_repository   => false,
    config_template           => 'telegraf/telegraf.conf.erb',
    # [outputs.influxdb] section of telegraf.conf
    outputs_influxdb_enabled  => true,
    outputs_influxdb_urls     => ['http://localhost:8086'],
    outputs_influxdb_database => 'telegraf',
    outputs_influxdb_username => 'telegraf',
    outputs_influxdb_password => 'metricsmetricsmetricsmetrics',
}

    config_directory          => '/etc/opt/telegraf/telegraf.d',

    # [outputs.influxdb] section of telegraf.conf
    outputs_influxdb_enabled  => true,
    outputs_influxdb_urls     => ['http://localhost:8086'],
    outputs_influxdb_database => 'telegraf',
    outputs_influxdb_username => 'telegraf',
    outputs_influxdb_password => 'metricsmetricsmetricsmetrics',

    # [tags] section of telegraf.conf
    tags                      => {
      virtual            => $::virtual,
      lsbdistdescription => $::lsbdistdescription,
      environment        => $::my_own_facter_environment,
      location           => $::my_own_facter_location,
    }

    # [agent]
    agent_hostname            => $::hostname,
    agent_interval            => '10s',

    # [[plugins.cpu]]
    cpu_percpu                => true,
    cpu_totalcpu              => true,
    cpu_drop                  => ["cpu_time"],

Testing Setup with Vagrant

Install and setup vagrant [https://docs.vagrantup.com/v2/installation/index.html](as described here).

Fetch virtual machines:

vagrant box add puppetlabs/ubuntu-14.04-64-puppet --insecure
vagrant box add puppetlabs/centos-6.6-64-puppet   --insecure
vagrant box add puppetlabs/centos-7.0-64-puppet   --insecure
vagrant box add puppetlabs/debian-7.8-64-puppet   --insecure
vagrant box add markusperl/debian-8.0-jessie-64-shrinked-puppet --insecure

Add vagrant puppet support and run tests:
