Overview

The influxdb module lets you use Puppet to install, configure, and manage Influxdb version 1.0.0+ The current InfluxDB version is 1.2.0

Deprecation Warning

InfluxDB 1.0.0 contains breaking changes which require changing the data-logging-enabled config attribute to trace-logging-enabled. The other configuration changes are managed by the influxdb.conf.erb template already.

If you are using an older version of InfluxDB, you will need to use version 0.5.0 of this module

Module Description

InfluxDB is a Open source distributed time series, events, and metrics database. This module handles the installation and every configuration parameters.

Support for Puppet 3.x and Puppet 4.x

Setup

Beginning with influxdb

To install InfluxDB with the default parameters

  class { 'influxdb': }

What influxdb affects

• influxdb package.
• influxdb configuration file.
• influxdb service.

Usage

To enable Graphite plugin :

  class { 'influxdb': 
    graphite => {
     main => {
        enabled => true,
     }
    }
  }

With InfluxDB, you can configure several graphite backends.

A more complex example

  class { 'influxdb': 
    graphite => {
     main => {
        enabled => true,
        database      => 'mygraphitedb',
        batch_size    => 500,
        tags          => ['region=us-east', 'zone=1c'],
        templates     => [
           "servers.* .host.measurement*",
           "stats.* .host.measurement* region=us-west,agent=sensu",
        ]
     },
     udp => {
        enabled => true,
        bind-address => ':20003',
        protocol => 'udp',
     }
    }
  }

To enable Collectd plugin:

  class { 'influxdb': 
    collectd => {  
      enabled => true,
    }
  }

Hiera Example

influxdb::package_ensure: 'latest'
influxdb::graphite:
 main:
   enabled: true
   batch_size: 3
influxdb::data:
  dir: '/mnt/influxdb/data'

Reference

Classes

Public Classes

• influxdb: Guides the basic setup of InfluxDB.

Private Classes

• influxdb::install: Installs InfluxDB packages.
• influxdb::config: Configures InfluxDB.
• influxdb::params: Manages InfluxDB parameters.
• influxdb::service: Manages the InfluxDB daemon.

Parameters

As InfluxDB is moving quickly, this module has a "dynamic" structure. Each section of the Influxdb configuration file is mapped to a hash. So you can easily add/remove new parameters as the influxdb software evolves, without change this module.

Section Hashes

Each config file section accepts a hash of values. Defaults are set in params.pp

Here are the default values for the meta section :

  $meta = {
    dir => '/var/lib/influxdb/meta',
    hostname => 'localhost',
    bind-address => ':8088',
    retention-autocreate => true,
    election-timeout => '1s',
    heartbeat-timeout => '1s',
    leader-lease-timeout => '500ms',
    commit-timeout => '50ms',
    cluster-tracing => false,
    raft-promotion-enabled => true,
    logging-enabled => true,
  }

package_ensure

Choose whether to install or uninstall, or force to the latest version. Default: present

manage_repo

Choose whether to configure influxdb repositories. Default: true

config_file

Full path to config file (e.g. /etc/influxdb/influxdb.conf). Defaults to "/etc/influxdb/influxdb.conf"

#### influxdb_user Ownership of influxdb directories. (Don't set user that will run influxdb ... yet) Default: 'influxdb'

influxdb_group

Group of influxdb directories. Default: 'influxdb'

conf_template

Specify template to use for influxdb conf file. Defaults to "influxdb/influxdb.conf.erb"

Defined Types

influxdb_database

influxdb_database { 'graphite':
  ensure  => 'present',
}

influxdb_retention_policy

influxdb_retention_policy creates retention policy on databases. To use it you must create the title of the resource as shown below, following the pattern of policy_name@database:

influxdb_retention_policy { '1w@graphite':
  ensure      => present,
  database    => 'graphite',
  duration    => '1w',
  is_default  => true,
  replication => '1',
}

Limitations

This module has been tested on:

• Debian 7 Wheezy
• Debian 8 Jessie

It should also work on Debian-based OS (Ubuntu) and RedHat osfamily

This module is fully compatible with Puppet 3.x and Puppet 4.x

Providers work without authentication/authorization (work in progress)
