Overview

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

Module Description

With the 9.0.0 release of this module we only support Grafana 6.x/7.x/8.x. Version 8 of the module was tested successfully on Grafana 6 and 7.

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

Requirements

• If using an operating system of the Debian-based family, and the "repo" install_method, you will need to ensure that puppetlabs-apt version 4.x is installed.
• If using Docker, you will need the garethr/docker module version 5.x

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 (or Sensitive[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          => 'mysql',
          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 = mysql
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.
• If your configuration contains secrets you want hidden in Puppet log output and reports use a Sensitive[Hash] instead of a normal Hash

ldap_cfg

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.

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

secrets

LDAP configuration usually contains secrets. If you want to stop these being leaked in logs and reports, the ldap_cfg parameter will optionally accept the Sensitive data type.

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',
},

Example LDAP config

ldap_cfg => Sensitive({
  servers => [
    { host            => 'ldapserver1.domain1.com',
      port            => 636,
      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     => 'mail',
  }
}),

If you want to connect to multiple LDAP servers using different configurations, use an array to enwrap the configurations as shown below.

ldap_cfg => Sensitive([
  {
    servers => [
      {
        host            => 'ldapserver1.domain1.com',
        port            => 636,
        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     => 'mail',
    },
    'servers.group_mappings' => [
      {
        group_dn => 'cn=grafana_viewers,ou=groups,dc=domain1,dc=com',
        org_role => 'Viewer',
      }
    ],
  },
  {
    servers => [
      {
        host            => 'ldapserver2.domain2.com',
        port            => 389,
        use_ssl         => false,
        start_tls       => true,
        search_filter   => '(uid=%s)',
        search_base_dns => [ 'dc=domain2,dc=com' ],
        bind_dn         => 'user@domain2.com',
        bind_password   => 'passwordhere',
      },
    ],
    'servers.attributes' => {
      name      => 'givenName',
      surname   => 'sn',
      username  => 'uid',
      member_of => 'memberOf',
      email     => 'mail',
    }
    'servers.group_mappings' => [
      {
        'group_dn'      => 'cn=grafana_admins,ou=groups,dc=domain2,dc=com',
        'org_role'      => 'Admin',
        'grafana_admin' => true,
      }
    ],
  },
])

#####

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.

plugins

Hash. This is a passthrough to call create_resources() on the grafana_plugin resource type.

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.

provisioning_datasources

A Hash which is converted to YAML for grafana to provision data sources. See provisioning grafana for details and example config file. Requires grafana > v5.0.0.

This is very useful with Hiera as you can provide a yaml hash/dictionary which will effectively 'passthrough' to grafana. See Advanced Usage for examples.

provisioning_dashboards

A Hash which is converted to YAML for grafana to provision dashboards. See provisioning grafana for details and example config file. Requires grafana > v5.0.0.

This is very useful with Hiera as you can provide a yaml hash/dictionary which will effectively 'passthrough' to grafana. See Advanced Usage for examples.

N.B. A option named puppetsource may be given in the options hash which is not part of grafana's syntax. This option will be extracted from the hash, and used to "source" a directory of dashboards. See Advanced Usage for details.

provisioning_dashboards_file

A String that is used as the target file name for the dashabords provisioning file. This way the module can be used to generate placeholder files so password can be sepecified in a different iteration, avoiding them to be put in the module code.

provisioning_datasources_file

A String that is used as the target file name for the datasources provisioning file. This way the module can be used to generate placeholder files so password can be sepecified in a different iteration, avoiding them to be put in the module code.

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 'installed'

sysconfig_location

The RPM and DEB packages bring with them the default environment files for the services. The default location of this file for Debian is /etc/default/grafana-server and for RedHat /etc/sysconfig/grafana-server.

sysconfig

A hash of environment variables for the service. This only has an effect for installations with RPM and DEB packages (if install_method is set to 'package' or 'repo').

Example:

sysconfig => {
  'http_proxy' => 'http://proxy.example.com',
}

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]

Using a sub-path for Grafana API

If you are using a sub-path for the Grafana API, you will need to set the grafana_api_path parameter for the following custom types:

• grafana_dashboard
• grafana_datasource
• grafana_organization
• grafana_user
• grafana_folder
• grafana_team
• grafana_membership
• grafana_dashboard_permission

For instance, if your sub-path is /grafana, the grafana_api_path must be set to /grafana/api. Do not add a trailing / (slash) at the end of the value.

If you are not using sub-paths, you do not need to set this parameter.

Custom Types and Providers

The module includes several custom types:

grafana_organization

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

grafana_organization { 'example_org':
  ensure           => present,
  grafana_url      => 'http://localhost:3000',

}

add permissions for team:

grafana_dashboard_permission { 'example_team_permission':
  ensure           => 'present',
  grafana_url      => 'http://localhost:3000',
  grafana_user     => 'admin',

ensure is required. If the resource should be present or absent

dashboard is required. The dashboard to set permissions for.

user is required if team not set. The user to add permissions for.

team is required if user not set. the team to add permissions for.

name is optional if the name will differ from example_team above.

organization is optional. Defaults to Main org.

grafana_membership

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

grafana_membership { 'example_membership':
  ensure           => 'present',
  grafana_url      => 'http://localhost:3000',
  grafana_user     => 'admin',
  grafana_password => '5ecretPassw0rd',
  membership_type  => 'team',

  target_name      => 'example_team',
  user_name        => 'example_user',
  role             => 'Viewer'
  }
}

A membership is the concept of a user belonging to a target - either a team or an organization

The user and target must both exist for a membership to be created

grafana_url, grafana_user, and grafana_password are required to create memberships via the API.

ensure is required. If the resource should be present or absent

membership_type is required. Either team or organization

target_name is required. Specifies the target of the membership.

user_name is required. Specifies the user that is the focus of the membership.

role is required. Specifies what rights to grant the user. Either Viewer, Editor or Admin

organization is optional when using the membership_type of team. Defaults to Main org.

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',
  grafana_api_path  => '/grafana/api',
  folder            => 'folder-name',
  organization      => 'NewOrg',
  content           => template('path/to/exported/file.json'),
}

content must be valid JSON, and is parsed before imported. You can use the JSON generated with the share/export functionality or from the API call to /dashboards/uid but must remove the fields "id", "uid", "title" and "version" to make the resource call idempotent. grafana_user and grafana_password are optional, and required when authentication is enabled in Grafana. grafana_api_path is optional, and only used when using sub-paths for the API. organization is optional, and used when creating a dashboard for a specific organization. folder is an optional parameter, but the folder resource must exist.

Example: Make sure the grafana-server service is up and running before creating the grafana_dashboard definition. One option is to use the http_conn_validator from the healthcheck module

http_conn_validator { 'grafana-conn-validator' :
  host     => 'localhost',
  port     => '3000',
  use_ssl  => false,
  test_url => '/public/img/grafana_icon.svg',
  require  => Class['grafana'],
}
-> grafana_dashboard { 'example_dashboard':
  grafana_url       => 'http://localhost:3000',
  grafana_user      => 'admin',
  grafana_password  => '5ecretPassw0rd',
  content           => template('path/to/exported/file.json'),
}

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',
  grafana_api_path => '/grafana/api',
  type             => 'influxdb',
  organization     => 'NewOrg',
  url              => 'http://localhost:8086',
  user             => 'admin',
  password         => '1nFlux5ecret',
  database         => 'graphite',
  access_mode      => 'proxy',
  is_default       => true,
  json_data        => template('path/to/additional/config.json'),
  secure_json_data => template('path/to/additional/secure/config.json')
}

Available types are: influxdb, elasticsearch, graphite, cloudwatch, mysql, opentsdb, postgres and prometheus

organization is used to set which organization a datasource will be created on. If this parameter is not set, it will default to organization ID 1 (Main Org. by default). If the default org is deleted, organizations will need to be specified.

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

Setting basic_auth to true will allow use of the basic_auth_user and basic_auth_password params.

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

Example: Make sure the grafana-server service is up and running before creating the grafana_datasource definition. One option is to use the http_conn_validator from the healthcheck module

http_conn_validator { 'grafana-conn-validator' :
  host     => 'localhost',
  port     => '3000',
  use_ssl  => false,
  test_url => '/public/img/grafana_icon.svg',
  require  => Class['grafana'],
}
-> 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'),
}

Note that the database is dynamic, setting things other than "database" for separate types. Ex: for Elasticsearch it will set the Index Name.

jsonData Settings

Note that there are separate options for json_data / secure_json_data based on the type of datasource you create.

Elasticsearch

esVersion - Required, either 2 or 5, set as a bare number.

timeField - Required. By default this is @timestamp, but without setting it in jsonData, the datasource won't work without refreshing it in the GUI.

timeInterval - Optional. A lower limit for the auto group by time interval. Recommended to be set to write frequency, for example "1m" if your data is written every minute.

Example:

json_data => {"esVersion":5,"timeField":"@timestamp","timeInterval":"1m"}

CloudWatch

authType - Required. Options are Access & Secret Key, Credentials File, or ARN.

-"keys" = Access & Secret Key

-"credentials" = Credentials File

-"arn" = ARN

When setting authType to credentials, the database param will set the Credentials Profile Name.

When setting authType to arn, another jsonData value of assumeRoleARN is available, which is not required for other authType settings

customMetricsNamespaces - Optional. Namespaces of Custom Metrics, separated by commas within double quotes.

defaultRegion - Required. Options are "ap-northeast-(1 or 2)", "ap-southeast-(1 or 2)", "ap-south-1", "ca-central-1", "cn-north-1", "eu-central-1", "eu-west-(1 or 2)", "sa-east-(1 or 2)", "us-east-(1 or 2)", "us-gov-west-1", "us-west-(1 or 2)".

timeField

Example:

{"authType":"arn","assumeRoleARN":"arn:aws:iam:*","customMetricsNamespaces":"Namespace1,Namespace2","defaultRegion":"us-east-1","timeField":"@timestamp"}

Graphite

graphiteVersion - Required. Available versions are 0.9 or 1.0.

tlsAuth - Set to true or false

tlsAuthWithCACert - Set to true or false

Example:

{"graphiteVersion":"0.9","tlsAuth":true,"tlsAuthWithCACert":false}

OpenTSDB

tsdbResolution - Required. Options are 1 or 2.

1 = second

2 = millisecond

tsdbVersion - Required. Options are 1, 2, or 3.

1    =    <=2.1

2    =    ==2.2

3    =    ==2.3

Example:

{"tsdbResolution:1,"tsdbVersion":3}

InfluxDB

grafana_plugin

An example is provided for convenience; for more details, please view the puppet strings docs.

grafana_plugin { 'grafana-simple-json-datasource':
  ensure => present,
}

It is possible to specify a custom plugin repository to install a plugin. This will use the --repo option for plugin installation with grafana_cli.

grafana_plugin { 'grafana-simple-json-datasource':
  ensure    => present,
  repo      => 'https://nexus.company.com/grafana/plugins',
}

It is also possible to specify a custom plugin url to install a plugin. This will use the --pluginUrl option for plugin installation with grafana_cli.

grafana_plugin { 'grafana-example-custom-plugin':
  ensure     => present,
  plugin_url => 'https://github.com/example/example-custom-plugin/zipball/v1.0.0'
}

grafana_folder

Creates and manages Grafana folders via the API.

The following example creates a folder named 'folder1':

grafana_folder { 'folder1':
  ensure            => present,
  grafana_url       => 'http://localhost:3000',
  grafana_api_path  => '/grafana/api',
  grafana_user      => 'admin',
  grafana_password  => '5ecretPassw0rd',
}

grafana_api_path is only required if using sub-paths for the API

grafana::user

Creates and manages a global grafana user via the API.

grafana_user { 'username':
  grafana_url       => 'http://localhost:3000',
  grafana_api_path  => '/grafana/api',
  grafana_user      => 'admin',
  grafana_password  => '5ecretPassw0rd',
  full_name         => 'John Doe',
  password          => 'Us3r5ecret',
  email             => 'john@example.com',
  organizations     => {
    'Example Org' => 'Editor',
    'Main org.'   => 'Viewer',
    'Another Org' => 'Admin',
  },
}

If organizations is specified, the user's organizations will be managed. These should be specified as a hash of organization names and roles.

If puppet is managing any of these organizations, they will be autorequired.

grafana::notification

Creates and manages a global alert notification channel via the API.

grafana_notification { 'channelname':
  grafana_url       => 'http://localhost:3000',
  grafana_api_path  => '/grafana/api',
  grafana_user      => 'admin',
  grafana_password  => '5ecretPassw0rd',

  name              => 'channelname',
  type              => 'email',
  is_default        => false,
  send_reminder     => false,
  frequency         => '20m',
  settings          => {
              addresses    => "alerts@example.com; it@example.com"
  }
}

Provisioning Grafana

Grafana documentation on provisioning.

This module will provision grafana by placing yaml files into /etc/grafana/provisioning/datasources and /etc/grafana/provisioning/dashboards by default.

Example datasource

A puppet hash example for Prometheus. The module will place the hash as a yaml file into /etc/gafana/provisioning/datasources/puppetprovisioned.yaml.

class { 'grafana':
  provisioning_datasources => {
    apiVersion  => 1,
    datasources => [
      {
        name      => 'Prometheus',
        type      => 'prometheus',
        access    => 'proxy',
        url       => 'http://localhost:9090/prometheus',
        isDefault => true,
      },
    ],
  }
}

Here is the same configuration example as a hiera hash.

grafana::provisioning_datasources:
  apiVersion: 1
  datasources:
    - name: 'Prometheus'
      type: 'prometheus'
      access: 'proxy'
      url: 'http://localhost:9090/prometheus'
      isDefault: true

Example dashboard

An example puppet hash for provisioning dashboards. The module will place the hash as a yaml file into /etc/grafana/provisioning/dashboards/puppetprovisioned.yaml by default. More details follow the examples.

class { 'grafana':
  provisioning_dashboards => {
    apiVersion => 1,
    providers  => [
      {
        name            => 'default',
        orgId           => 1,
        folder          => '',
        type            => 'file',
        disableDeletion => true,
        options         => {
          path         => '/var/lib/grafana/dashboards',
          puppetsource => 'puppet:///modules/my_custom_module/dashboards',
        },
      },
    ],
  }
}

Here is the same configuraiton example as a hiera hash.

grafana::provisioning_dashboards:
  apiVersion: 1
  providers:
    - name: 'default'
      orgId: 1
      folder: ''
      type: file
      disableDeletion: true
      options:
        path: '/var/lib/grafana/dashboards'
        puppetsource: 'puppet:///modules/my_custom_module/dashboards'

In both examples above a non-grafana option named puppetsource has been used. When this module finds that the provisioning_dashboards hash contains keys path and puppetsource in the options subhash, it will do the following.

• It will create the path found in options['path']. Note: puppet will only create the final directory of the path unless the parameter create_subdirs_provisioning is set to true: this defaults to false.
• It will use puppetsource as the file resource's 'source' for the directory.
• It removes the puppetsource key from the options subhash, so the subsequent yaml file for gafana does not contain this key. (The path key will remain.)

This feature allows you to define a custom module, and place any dashboards you want provisioned in the its files/ directory. In the example above you would put dashboards into my_custom_module/files/dashboards and puppet-grafana will create /var/lib/grafana/dashboards and provision it with the contents of my_custom_module/files/dashboards.

Puppet's file resource may also be given a file:// URI which may point to a locally available directory on the filesystem, typically the filesystem of the puppetserver/master. Thus you may specify a local directory with grafana dashboards you wish to provision into grafana.

Provisioning with dashboards from grafana.com

GrafanaLabs provides lots of dashboards that may be reused. Those ones are not directly usable for provisioning (this is a Grafana issue, not a Puppet one).

In order to have a "provisionable" dashboard in JSON format, you have to prepare it before adding it in your Puppet code. Here are the steps to follow:

1. Use a Grafana instance
2. Import the desired dashboard
3. Define its datasource
4. From the dashboard view:
   • Click the "Share dashboard" icon (top left corner of screen)
   • Select the "Export" tab,
   • Activate "Export for sharing externally"
   • Click "Save to file"
5. In the JSON file:
   • Remove the keys __imports and __requires
   • Replace all ${DS_PROMETHEUS} by your datasource name
6. Once saved, you may place this JSON file in your puppet:///modules/my_custom_module/dashboards directory

Note:

This procedure have been tested with Grafana 6.x. It may not work for any dashboard, depending on how it's been coded.

Dashboards known to be "provisionable":

• Node Exporter Server Metric
• Prometheus Blackbox Exporter

Dashboards known not to be "provisionable":

• HTTP Services Status

Tasks

change_grafana_admin_password

old_password: the old admin password

new_password: the password you want to use for the admin user

uri: http or https

port: the port Grafana runs on locally

This task can be used to change the password for the admin user in grafana

Limitations

This module has been tested on every operating system in the metadata.json, using each of the 'archive', 'docker' and 'package' installation methods. Other configurations should work with minimal, if any, additional effort.

Development

This module is a fork of bfraser/grafana maintained by Vox Pupuli. Vox Pupuli welcomes new contributions to this module, especially those that include documentation and rspec tests. We are happy to provide guidance if necessary.

Please see CONTRIBUTING for more details.
