We run a couple of automated
scans to help you access a
module's quality. Each module is
given a score based on how well
the author has formatted their
code and documentation and
modules are also checked for
malware using VirusTotal.

Please note, the information below

Overview

This module manages both the Graphite Django-based web frontend and/or the lighter API frontend.

Module Description

This module installs the relevant frontend packages, configures them and optionally enables LDAP authentication and/or caching via Memcached or Redis where possible. It also manages running the frontend either directly as a standalone service or through a webserver such as Apache.

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 graphite affects

  • The package(s) providing the Graphite web software.
  • The /etc/graphite-web/local_settings.py configuration file.
  • Creating the database schema.
  • Generating a basic Apache virtual host configuration.
  • The package(s) providing the Graphite API software.
  • The /etc/graphite-api.yaml configuraton file.
  • The service controlling the running of Graphite API as a daemon.

Examples

Install Graphite API in front of a single carbon cache instance:

include ::carbon

class { '::graphite::api':
  carbon_hosts => [
    {
      'host' => '127.0.0.1',
      'port' => 7002,
    },
  ],
  require      => Class['::carbon'],
}

Extend the above to include a Memcached caching layer:

include ::carbon
include ::memcached

class { '::graphite::api':
  carbon_hosts => [
    {
      'host' => '127.0.0.1',
      'port' => 7002,
    },
  ],
  require      => Class['::carbon'],
}

class { '::graphite::api::memcached':
  servers => [
    {
      'host' => '127.0.0.1',
      'port' => 11211,
    },
  ],
  require => Class['::memcached'],
}

Use Redis instead:

include ::carbon
include ::redis

class { '::graphite::api':
  carbon_hosts => [
    {
      'host' => '127.0.0.1',
      'port' => 7002,
    },
  ],
  require      => Class['::carbon'],
}

class { '::graphite::api::redis':
  host    => '127.0.0.1',
  require => Class['::redis'],
}

Install Graphite web in front of a single carbon cache instance with Memcached caching enabled:

include ::carbon
include ::memcached

class { '::apache':
  default_confd_files => false,
  default_mods        => false,
  default_vhost       => false,
}

class { '::graphite::web':
  secret_key       => 'abc123',
  carbonlink_hosts => [
    {
      'host' => '127.0.0.1',
      'port' => 7002,
    },
  ],
  memcache_hosts   => [
    {
      'host' => '127.0.0.1',
      'port' => 11211,
    },
  ],
  require          => Class['::carbon'],
}

Extend the above to also configure LDAP authentication:

include ::openldap
include ::openldap::client
class { '::openldap::server':
  root_dn              => 'cn=Manager,dc=example,dc=com',
  root_password        => 'secret',
  suffix               => 'dc=example,dc=com',
  access               => [
    'to attrs=userPassword by self =xw by anonymous auth',
    'to * by dn.base="gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth" manage by users read',
  ],
  ldap_interfaces      => ['127.0.0.1'],
  local_ssf            => 256,
}
::openldap::server::schema { 'cosine':
  position => 1,
}
::openldap::server::schema { 'inetorgperson':
  position => 2,
}
::openldap::server::schema { 'nis':
  position => 3,
}

include ::carbon
include ::memcached

class { '::apache':
  default_confd_files => false,
  default_mods        => false,
  default_vhost       => false,
}

class { '::graphite::web':
  secret_key       => 'abc123',
  carbonlink_hosts => [
    {
      'host' => '127.0.0.1',
      'port' => 7002,
    },
  ],
  memcache_hosts   => [
    {
      'host' => '127.0.0.1',
      'port' => 11211,
    },
  ],
  require          => Class['::carbon'],
}

class { '::graphite::web::ldap':
  bind_dn       => 'cn=Manager,dc=example,dc=com',
  bind_password => 'secret',
  search_base   => 'dc=example,dc=com',
  search_filter => '(uid=%s)',
  uri           => 'ldap://127.0.0.1',
  require       => Class['::openldap::server'],
}

Limitations

This module intentionally doesn't manage the Carbon daemons, see my other module which does that.

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.
