##Overview

This module installs Grafana, a dashboard and graph editor for Graphite, InfluxDB and OpenTSDB.

##Module Description

Version 2.x of this module is designed to work with version 2.x of Grafana. If you would like to continue to use Grafana 1.x, please use version 1.x of this module.

##Setup

This module will:

  • Install Grafana using your preferred method: package (default), Docker container, or tar archive
  • Allow you to override the version of Grafana to be installed, and / or the package source
  • Perform basic configuration of Grafana

###Beginning with Grafana

To install Grafana with the default parameters:

    class { 'grafana': }

This assumes that you want to install Grafana using the 'package' method. To establish customized parameters:

    class { 'grafana':
      install_method  => 'docker',
    }

##Usage

###Classes and Defined Types

####Class: grafana

The Grafana module's primary class, grafana, guides the basic setup of Grafana on your system.

    class { 'grafana': }

Parameters within grafana:

#####archive_source

The download location of a tarball to use with the 'archive' install method. Defaults to the URL of the latest version of Grafana available at the time of module release.

#####cfg_location

Configures the location to which the Grafana configuration is written. The default location is '/etc/grafana/grafana.ini'.

#####cfg

Manages the Grafana configuration file. Grafana comes with its own default settings in a different configuration file (/opt/grafana/current/conf/defaults.ini), therefore this module does not supply any defaults.

This parameter only accepts a hash as its value. Keys with hashes as values will generate sections, any other values are just plain values. The example below will result in...

    class { 'grafana':
      cfg => {
        app_mode => 'production',
        server   => {
          http_port     => 8080,
        },
        database => {
          type          => 'sqlite3',
          host          => '127.0.0.1:3306',
          name          => 'grafana',
          user          => 'root',
          password      => '',
        },
        users    => {
          allow_sign_up => false,
        },
      },
    }

...the following Grafana configuration:

# This file is managed by Puppet, any changes will be overwritten

app_mode = production

[server]
http_port = 8080

[database]
type = sqlite3
host = 127.0.0.1:3306
name = grafana
user = root
password =

[users]
allow_sign_up = false

Some minor notes:

  • If you want empty values, just use an empty string.
  • Keys that contains dots (like auth.google) need to be quoted.
  • The order of the keys in this hash is the same as they will be written to the configuration file. So settings that do not fall under a section will have to come before any sections in the hash.

####ldap_cfg

#####TOML note This option requires the toml gem. Either install the gem using puppet's native gem provider, puppetserver_gem, pe_gem, pe_puppetserver_gem, or manually using one of the following:

  # apply or puppet-master
  gem install toml
  # PE apply
  /opt/puppet/bin/gem install toml
  # AIO or PE puppetserver
  /opt/puppet/bin/puppetserver gem install toml

#####cfg note This option by itself is not sufficient to enable LDAP configuration as it must be enabled in the main configuration file. Enable it in cfg with:

'auth.ldap' => {
  enabled     => 'true',
  config_file => '/etc/grafana/ldap.toml',
},

####Integer note Puppet may convert integers into strings while parsing the hash and converting into toml. This can be worked around by appending 0 to an integer.

Example:

port => 636+0,

Manages the Grafana LDAP configuration file. This hash is directly translated into the corresponding TOML file, allowing for full flexibility in generating the configuration.

See the LDAP documentation for more information.

####Example LDAP config

ldap_cfg => {
  servers => [
    { host            => 'ldapserver1.domain1.com',
      port            => 636+0,
      use_ssl         => true,
      search_filter   => '(sAMAccountName=%s)',
      search_base_dns => [ 'dc=domain1,dc=com' ],
      bind_dn         => 'user@domain1.com',
      bind_password   => 'passwordhere',
    },
  ],
  'servers.attributes' => {
    name      => 'givenName',
    surname   => 'sn',
    username  => 'sAMAccountName',
    member_of => 'memberOf',
    email     => 'email',
  }
},

#####container_cfg

Boolean to control whether a configuration file should be generated when using the 'docker' install method. If 'true', use the 'cfg' and 'cfg_location' parameters to control creation of the file. Defaults to false.

#####container_params

A hash of parameters to use when creating the Docker container. For use with the 'docker' install method. Refer to documentation of the 'docker::run' resource in the garethr-docker module for details of available parameters. Defaults to:

container_params => {
  'image' => 'grafana/grafana:latest',
  'ports' => '3000:3000'
}

#####data_dir

The directory Grafana will use for storing its data. Defaults to '/var/lib/grafana'.

#####install_dir

The installation directory to be used with the 'archive' install method. Defaults to '/usr/share/grafana'.

#####install_method

Controls which method to use for installing Grafana. Valid options are: 'archive', 'docker', 'repo' and 'package'. The default is 'package'. If you wish to use the 'docker' installation method, you will need to include the 'docker' class in your node's manifest / profile. If you wish to use the 'repo' installation method, you can control whether the official Grafana repositories will be used. See manage_package_repo below for details.

#####manage_package_repo

Boolean. When using the 'repo' installation method, controls whether the official Grafana repositories are enabled on your host. If true, the official Grafana repositories will be enabled. If false, the module assumes you are managing your own package repository and will not set one up for you. Defaults to true.

#####package_name

The name of the package managed with the 'package' install method. Defaults to 'grafana'.

#####package_source

The download location of a package to be used with the 'package' install method. Defaults to the URL of the latest version of Grafana available at the time of module release.

#####rpm_iteration

Used when installing Grafana from package ('package' or 'repo' install methods) on Red Hat based systems. Defaults to '1'. It should not be necessary to change this in most cases.

#####service_name

The name of the service managed with the 'archive' and 'package' install methods. Defaults to 'grafana-server'.

#####version

The version of Grafana to install and manage. Defaults to the latest version of Grafana available at the time of module release.

##Advanced usage:

The archive install method will create the user and a "command line" service by default. There are no extra parameters to manage user/service for archive. However, both check to see if they are defined before defining. This way you can create your own user and service with your own specifications. (sort of overriding) The service can be a bit tricky, in this example below, the class sensu_install::grafana::service creates a startup script and a service{'grafana-server':}

Example:

    user { 'grafana':
      ensure   => present,
      uid      => '1234',
    }
    ->
    class { 'grafana':
      install_method  => 'archive',
    }

    include sensu_install::grafana::service

    # run your service after install/config but before grafana::service
    Class[::grafana::install]
    ->
    Class[sensu_install::grafana::service]
    ->
    Class[::grafana::service]

####Custom Types and Providers

The module includes two custom types: grafana_dashboard and grafana_datasource

#####grafana_dashboard

In order to use the dashboard resource, add the following to your manifest:

grafana_dashboard { 'example_dashboard':
  grafana_url       => 'http://localhost:3000',
  grafana_user      => 'admin',
  grafana_password  => '5ecretPassw0rd',
  content           => template('path/to/exported/file.json'),
}

content must be valid JSON, and is parsed before imported. grafana_user and grafana_password are optional, and required when authentication is enabled in Grafana.

#####grafana_datasource

In order to use the datasource resource, add the following to your manifest:

grafana_datasource { 'influxdb':
  grafana_url       => 'http://localhost:3000',
  grafana_user      => 'admin',
  grafana_password  => '5ecretPassw0rd',
  type              => 'influxdb',
  url               => 'http://localhost:8086',
  user              => 'admin',
  password          => '1nFlux5ecret',
  database          => 'graphite',
  access_mode       => 'proxy',
  is_default        => true,
  json_data         => template('path/to/additional/config.json'),
}

Available types are: influxdb, elasticsearch, graphite, kairosdb, opentsdb, prometheus

Access mode determines how Grafana connects to the datasource, either direct from the browser, or proxy to send requests via grafana.

Authentication is optional, as is database; additional json_data can be provided to allow custom configuration options.

##Limitations

This module has been tested on Ubuntu 14.04, using each of the 'archive', docker' and 'package' installation methods. Other configurations should work with minimal, if any, additional effort.
