Overview

This module installs and makes basic configs for graphite, with carbon and whisper.

Module Description

Graphite, and its components Carbon and Whisper, is an enterprise-scale monitoring tool. This module sets up a simple graphite server with all its components. Furthermore it can be used to set up more complex graphite environments with metric aggregation, clustering and so on.

Setup

What graphite affects:

packages/services/configuration files for Graphite
on default sets up webserver (can be disabled if manage by other module)

Beginning with Graphite

To install Graphite with default parameters

    class { 'graphite': }

The defaults are determined by your operating system e.g. Debian systems have one set of defaults, and RedHat systems have another). This defaults should work well on testing environments with graphite as a standalone service on the machine. For production use it is recommend to use a database like MySQL and cache data in memcached (not installed with this module) and configure it here. Furthermore you should check things like gr_storage_schemas.

Configure MySQL and Memcached

  class { 'graphite':
    gr_max_updates_per_second => 100,
    gr_timezone               => 'Europe/Berlin',
    secret_key                => 'CHANGE_IT!',
    gr_storage_schemas        => [
      {
        name       => 'carbon',
        pattern    => '^carbon\.',
        retentions => '1m:90d'
      },
      {
        name       => 'special_server',
        pattern    => '^longtermserver_',
        retentions => '10s:7d,1m:365d,10m:5y'
      },
      {
        name       => 'default',
        pattern    => '.*',
        retentions => '60:43200,900:350400'
      }
    ],
    gr_django_db_engine       => 'django.db.backends.mysql',
    gr_django_db_name         => 'graphite',
    gr_django_db_user         => 'graphite',
    gr_django_db_password     => 'MYsEcReT!',
    gr_django_db_host         => 'mysql.my.domain',
    gr_django_db_port         => '3306',
    gr_memcache_hosts         => ['127.0.0.1:11211']
  }

Configure Graphite with Grafana

This setup will use the puppetlabs-apache and bfraser-grafana modules to setup a graphite system with grafana frontend. You will also need an elasticsearch as it is required for grafana.

include '::apache'

apache::vhost { 'graphite.my.domain':
  port    => '80',
  docroot => '/opt/graphite/webapp',
  wsgi_application_group      => '%{GLOBAL}',
  wsgi_daemon_process         => 'graphite',
  wsgi_daemon_process_options => {
    processes          => '5',
    threads            => '5',
    display-name       => '%{GROUP}',
    inactivity-timeout => '120',
  },
  wsgi_import_script          => '/opt/graphite/conf/graphite_wsgi.py',
  wsgi_import_script_options  => {
    process-group     => 'graphite',
    application-group => '%{GLOBAL}'
  },
  wsgi_process_group          => 'graphite',
  wsgi_script_aliases         => {
    '/' => '/opt/graphite/conf/graphite_wsgi.py'
  },
  headers => [
    'set Access-Control-Allow-Origin "*"',
    'set Access-Control-Allow-Methods "GET, OPTIONS, POST"',
    'set Access-Control-Allow-Headers "origin, authorization, accept"',
  ],
  directories => [{
    path => '/media/',
    order => 'deny,allow',
    allow => 'from all'}
  ]
}->
class { 'graphite':
  gr_web_server           => 'none',
  gr_disable_webapp_cache => true,
}

class {'grafana':
 # see manual of this module
}

Configuration with Apache 2.4 and CORS

If you use a system which ships Apache 2.4, then you will need a slightly different vhost config. Here is an example with Apache 2.4 and CORS enabled. If you do not know what CORS, then do not use it. Its disabled by default. You will need CORS for Webguis like Grafana.

  class { 'graphite':
    gr_apache_24               => true,
    gr_web_cors_allow_from_all => true,
    secret_key                 => 'CHANGE_IT!'
  }

Configuration with Additional LDAP Options

If additional LDAP parameters are needed for your Graphite installation, you can specify them using the gr_ldap_options parameter. For example, this is useful if you're using SSL and need to configure LDAP to use your SSL cert and key files.

This Puppet configuration...

  class { 'graphite':
    gr_ldap_options => {
      'ldap.OPT_X_TLS_REQUIRE_CERT' => 'ldap.OPT_X_TLS_ALLOW',
      'ldap.OPT_X_TLS_CACERTDIR'    => '"/etc/ssl/ca"',
      'ldap.OPT_X_TLS_CERTFILE'     => '"/etc/ssl/mycert.crt"',
      'ldap.OPT_X_TLS_KEYFILE'      => '"/etc/ssl/mykey.pem"',
    },
  }

... adds these lines to the local_settings.py configuration file for Graphite web.

import ldap
ldap.set_option(ldap.OPT_X_TLS_CACERTDIR, "/etc/ssl/ca")
ldap.set_option(ldap.OPT_X_TLS_CERTFILE, "/etc/ssl/mycert.crt")
ldap.set_option(ldap.OPT_X_TLS_KEYFILE, "/etc/ssl/mykey.pem")
ldap.set_option(ldap.OPT_X_TLS_REQUIRE_CERT, ldap.OPT_X_TLS_ALLOW)

See http://www.python-ldap.org/ for more details about these options.

Configuration with multiple cache, relay and/or aggregator instances

You could create more than one instance for cache, relay or aggregator using the gr_cache_instances, gr_relay_instances and gr_aggregator_instances parameters. These paremeters must be hashes, and the keys are the name of the instances (cache:b, cache:c, relay:b, relay:c, etc.). Every hash must have an array of parameters which will be written as is in the config file. The defaults settings for the additional instances will be the ones set for the principal instance.

   class {'graphite':
      gr_line_receiver_port => 2003,
      gr_pickle_receiver_port => 2004,
      gr_cache_query_port => 7002,

      gr_cache_instances => {
         'cache:b' => {
            'LINE_RECEIVER_PORT' => 2103,
            'PICKLE_RECEIVER_PORT' => 2104,
            'CACHE_QUERY_PORT' => 7102,
         },
         'cache:c' => {
            'LINE_RECEIVER_PORT' => 2203,
            'PICKLE_RECEIVER_PORT' => 2204,
            'CACHE_QUERY_PORT' => 7202,
         }
      }
   }

So in this case you would have 3 cache instances, the first one is cache (you can refer to it as cache:a too), cache:b and cache:c. cache:a will listen on ports 2003, 2004 and 7002 for line, pickle and query respectively. But, cache:b will do it on ports 2103, 2104, and 7102, and cache:c on 2203, 2204 and 7202. All other parameters from cache:a will be inherited by cache:b and c.

Install Graphite 1.1 and enable tag-support

Taged metrics are available in Graphite/Carbon 1.1.1 and later. To use tags Carbon has to add tags to a TagDB (see https://graphite.readthedocs.io/en/latest/tags.html) for details. To enable this feature in Carbon set the parameter gr_tags_enable to true. This will configure Carbon to pass tags to Graphite-web listening on 127.0.0.1 and port gr_web_server_port. Redis and HTTP(S) Tag DBs are not yet supported.

To use tags at least version 1.1.1 of Graphite-Web/Carbopn/Whisper as well as compatible versions of Django, Django Tagging and Twisted have to be installed.

class { 'graphite': 
    gr_tags_enable            => true,
    #
    # Needed to install / upgrade to Graphite 1.1
    #
    gr_graphite_ver           => '1.1.7',
    gr_carbon_ver             => '1.1.7',
    gr_whisper_ver            => '1.1.7',
    gr_django_ver             => '1.11',
    gr_django_tagging_ver     => '0.4.6',
    gr_twisted_ver            => '20.3.0',
    gr_django_init_command    => 'PYTHONPATH=/opt/graphite/webapp /usr/local/bin/django-admin.py migrate --setting=graphite.settings --fake-initial',
    gr_django_init_provider   => 'shell',
}

Installing with something other than pip and specifying package names and versions

If you need to install via something other than pip, an internal apt repo with fpm converted packages for instance, you can set gr_pip_install to false. If you're doing this you'll most likely have to override the default package names and versions as well.

  class { '::graphite':
    gr_pip_install        => false,
    gr_django_tagging_pkg => 'python-django-tagging',
    gr_django_tagging_ver => 'present',
    gr_twisted_pkg        => 'python-twisted',
    gr_twisted_ver        => 'present',
    gr_txamqp_pkg         => 'python-txamqp',
    gr_txamqp_ver         => 'present',
    gr_graphite_pkg       => 'python-graphite-web',
    gr_graphite_ver       => 'present',
    gr_carbon_pkg         => 'python-carbon',
    gr_carbon_ver         => 'present',
    gr_whisper_pkg        => 'python-whisper',
    gr_whisper_ver        => 'present',
  }

Additionally, the Django package is normally installed from a system package, but can be changed to install from pip instead.

  class { '::graphite':
    gr_django_pkg      => 'django',
    gr_django_ver      => '1.5',
    gr_django_provider => 'pip',
  }

Managing system pip and Python development packages

If gr_pip_install is set to true, both python-pip and Python development packages will need to be installed. If you want to manage those packages separately, set gr_manage_python_packages to false.

class { '::graphite': gr_pip_install => true, gr_manage_python_packages => false, }

Installing with pip from a non-PyPI source

You can also chose to install the pip packages from a source other than PyPI, such as a file on disk or an HTTP server. If you do this you will also have to set the package versions to 'present' to avoid errors from Puppet:

  class { '::graphite':
    gr_django_tagging_ver    => 'present',
    gr_django_tagging_source => 'http://example.com/django-tagging-0.3.1.tar.gz',
    gr_twisted_ver           => 'present',
    gr_twisted_source        => 'http://example.com/Twisted-11.1.0.tar.bz2',
    gr_txamqp_ver            => 'present',
    gr_txamqp_source         => 'http://example.com/txAMQP-0.4.tar.gz',
    gr_graphite_ver          => 'present',
    gr_graphite_source       => 'http://example.com/graphite-web-0.9.15.tar.gz',
    gr_carbon_ver            => 'present',
    gr_carbon_source         => 'http://example.com/carbon-0.9.15.tar.gz',
    gr_whisper_ver           => 'present',
    gr_whisper_source        => 'http://example.com/whisper-0.9.15.tar.gz',
  }

You can also specify an alternate source for all packages (and their dependencies) by passing options to pip install using gr_pip_install_options:

  class { '::graphite':
    gr_pip_install_options => [
      '--no-index',
      '--find-links', 'https://example.com/pip_packages/',
    ],
  }

For more details on how these options work, see the documentation for pip install.

Requirements

Modules needed:

stdlib by puppetlabs

Software versions needed:

On Redhat distributions you need the EPEL or RPMforge repository, because Graphite needs packages, which are not part of the default repos.

Limitations

This module is tested on CentOS 6.5 and Debian 7 (Wheezy) and should also run on

RHEL/CentOS/Scientific 6+
Debian 6+
Ubunutu 10.04 and newer

Most settings of Graphite can be set by parameters. So their can be special configurations for you. In this case you should edit the file templates/opt/graphite/webapp/graphite/local_settings.py.erb.

Compatibility Notes

There is currently an open ticket with Puppet about broken pip support in CentOS 6/7. The workaround for this bug is to create a symlink from /usr/bin/pip-python (which doesn't exist) to /usr/bin/pip (which does).
CentOS 7's default nginx.conf includes a server section listening on port 80. Thus, it is not possible to set up graphite without modifying the package-provided configuration file. You will have to either manually remove the server section, or provide a gr_web_server_port other than port 80.
nginx/gunicorn requires a systemctl restart gunicorn after installing on Ubuntu 15.10
SELinux must be disabled
Installing on Ubuntu 16.04 Xenial requires Puppet 4.1+ (see commit 71251c9)
