Collectd module for Puppet

Description

Puppet module for configuring collectd and plugins.

Usage

The simplest use case is to use all of the configurations in the default collectd.conf file shipped with collectd. This can be done by simply including the class:

include collectd

Collectd is most useful when configured with customized plugins. This is accomplished by removing the default collectd.conf file and replacing it with a file that includes all alternative configurations. Configure a node with the following class declaration:

class { '::collectd':
  purge        => true,
  recurse      => true,
  purge_config => true,
}

Set purge, recurse, and purge_config to true in order to override the default configurations shipped in collectd.conf and use custom configurations stored in conf.d. From here you can set up additional plugins as shown below.

Simple Plugins

Example of how to load plugins with no additional configuration:

collectd::plugin { 'battery': }

where 'battery' is the name of the plugin.

Configurable Plugins

Parameters will vary widely between plugins. See the collectd documentation for each plugin for configurable attributes.

}

####Class: collectd::plugin::openvpn

• statusfile (String or Array) Status file(s) to collect data from. (Default /etc/openvpn/openvpn-status.log)
• improvednamingschema (Bool) When enabled, the filename of the status file will be used as plugin instance and the client's "common name" will be used as type instance. This is required when reading multiple status files. (Default: false)
• collectcompression Sets whether or not statistics about the compression used by OpenVPN should be collected. This information is only available in single mode. (Default true)
• collectindividualusers Sets whether or not traffic information is collected for each connected client individually. If set to false, currently no traffic data is collected at all because aggregating this data in a save manner is tricky. (Default true)
• collectusercount When enabled, the number of currently connected clients or users is collected. This is especially interesting when CollectIndividualUsers is disabled, but can be configured independently from that option. (Default false)

Watch multiple statusfiles:

class { 'collectd::plugin::openvpn':
  statusfile             => [ '/etc/openvpn/openvpn-status-tcp.log', '/etc/openvpn/openvpn-status-udp.log' ],

  collectusercount       => true,
}

####Class: collectd::plugin::perl

This class has no parameters and will load the actual perl plugin. It will be automatically included if any perl::plugin is defined.

#####Example:

include collectd::plugin::perl

####Define: collectd::plugin::perl::plugin

This define will load a new perl plugin.

#####Parameters:

• module (String): name of perl module to load (mandatory)
• enable_debugger (False or String): whether to load the perl debugger. See collectd-perl manpage for more details.
• include_dir (String or Array): directories to add to @INC
• provider ("package","cpan","file" or false): method to get the plugin code
• source (String): this parameter is consumed by the provider to infer the source of the plugin code
• destination (String or false): path to plugin code if providerisfile`. Ignored otherwise.
• order (String containing numbers): order in which the plugin should be loaded. Defaults to "00"
• config (Hash): plugin configuration in form of a hash. This will be converted to a suitable structure understood by liboconfig which is the collectd configuration parser. Defaults to {}

#####Examples:

######Using a preinstalled plugin:

collectd::plugin::perl::plugin { 'foo':
    module          => 'Collectd::Plugins::Foo',
    enable_debugger => "",
    include_dir     => '/usr/lib/collectd/perl5/lib',
}

######Using a plugin from a file from source:

collectd::plugin::perl::plugin { 'baz':
    module      => 'Collectd::Plugins::Baz',
    provider    => 'file',
    source      => 'puppet:///modules/myorg/baz_collectd.pm',
    destination => '/path/to/my/perl5/modules'
}

######Using a plugin from cpan (requires the puppet cpan module):

  'openafs_vos':
    module        => 'Collectd::Plugins::OpenAFS::VOS',
    provider      => 'cpan',
    source        => 'Collectd::Plugins::OpenAFS',
    config        => {'VosBin' => '/usr/afsws/etc/vos'},
}

######Using a plugin from package source:

  'bar':
    module        => 'Collectd::Plugins::Bar',
    provider      => 'package',
    source        => 'perl-Collectd-Plugins-Bar',

    instanceprefix => 'log_delay',
    instancesfrom  => 'inet_server_port',
    valuesfrom     => 'log_delay',
  }],
}
collectd::plugin::postgresql::writer{'sqlstore':
  statement  => 'SELECT collectd_insert($1, $2, $3, $4, $5, $6, $7, $8, $9);',
  storerates => 'true',
}

You can as well configure this plugin as a parameterized class :

class { 'collectd::plugin::postgresql':
  databases => {
    'postgres' => {
      'host'     => '/var/run/postgresql/',
      'user'     => 'postgres',
      'password' => 'postgres',
      'sslmode'  => 'disable',
      'query'    => [ 'query_plans', 'queries', 'table_states', 'disk_io' ],
    },
    'devdb' => {
      'host'     => 'host.example.com',
      'port'     => '5432',
      'user'     => 'postgres',
      'password' => 'secret',
      'sslmode'  => 'prefer',
    }
  }
}

####Class: collectd::plugin::processes

You can either specify processes / process matches at once:

class { 'collectd::plugin::processes':
  processes => ['process1', 'process2'],
  process_matches => [
    { name => 'process-all', regex => 'process.*' }
  ],
}

Or define single processes / process matches:

collectd::plugin::processes::process { 'collectd' : }

collectd::plugin::processes::processmatch { 'elasticsearch' :
  regex => '.*java.*org.elasticsearch.bootstrap.Elasticsearch'
}

####Class: collectd::plugin::protocols

• values is an array of Protocol names, Protocol:ValueName pairs, or a regex
• see /proc/net/netstat and /proc/net/snmp for a list of Protocol targets

See [collectd.conf documentation] (https://collectd.org/documentation/manpages/collectd.conf.5.shtml#plugin_protocols) for details

class { 'collectd::plugin::protocols':
  values => ['/^Tcp:*/', '/^Udp:*/', 'Icmp:InErrors' ],
  ignoreselected => false,
}

####Class: collectd::plugin::python

• modulepaths is an array of paths where will be Collectd looking for Python modules, Puppet will ensure that each of specified directories exists and it is owned by root (and chmod 0750). If you don't specify any modulepaths a default value for given distribution will be used.
• modules a Hash containing configuration of Python modules, where the key is the module name
• globals Unlike most other plugins, this one should set Globals true. This will cause collectd to export the name of all objects in the Python interpreter for all plugins to see. If you don't do this or your platform does not support it, the embedded interpreter will start anyway but you won't be able to load certain Python modules, e.g. "time".
• interactive when true it will launch an interactive Python interpreter that reads from and writes to the terminal (default: false)
• logtraces if a Python script throws an exception it will be logged by collectd with the name of the exception and the message (default: false)

See collectd-python documentation for more details.

NOTE: Since v3.4.0 the syntax of this plugin has changed. Make sure to update your existing configuration. Now you can specify multiple Python modules at once:

class { 'collectd::plugin::python':
  modulepaths => ['/usr/share/collectd/python'],
  modules     => {
    'elasticsearch' => {
      'script_source' => 'puppet:///modules/myorg/elasticsearch_collectd_python.py',
      'config'        => {'Cluster' => 'elasticsearch'},
    },
    'another-module' => {
      'config'        => {'Verbose' => 'true'},
    }
  }
  logtraces   => true,
  interactive => false
}

When script_source provided, a file called {module}.py will be created in $modulepath/$module.py.

Or define single module:

collectd::plugin::python::module {'zk-collectd':
  script_source => 'puppet:///modules/myorg/zk-collectd.py',
  config        => {
    'Hosts' => "localhost:2181"
  }
}

Each plugin might use different modulepath, however make sure that all paths are included in collectd::plugin::python variable modulepaths. If no modulepath is specified, OS default will be used.

collectd::plugin::python::module {'my-module':
  modulepath    => '/var/share/collectd',
  script_source => 'puppet:///modules/myorg/my-module.py',
  config        => {
    'Key' => "value"
  }
}

####Class: collectd::plugin::write_graphite

The write_graphite plugin writes data to Graphite, an open-source metrics storage and graphing project.

  graphiteport   => 2003,
  graphiteprefix => '',
  protocol       => 'tcp'
}

You can define multiple Graphite backends where will be metrics send. Each backend should have unique title:

collectd::plugin::write_graphite::carbon {'secondary_graphite':
  graphitehost      => 'graphite.example.org',
  graphiteport      => 2004,
  graphiteprefix    => '',

types.db

Collectd needs to know how to handle each collected datapoint. For this it uses a database file called types.db

Those files can be created using the collectd::typesdb and collectd::type define resources.

$db = '/etc/collectd/types.db'
collectd::typesdb { $db: }

collectd::type { "response_size:${db}":
  target  => $db,
  ds_type => 'ABSOLUTE',
  min     => 0,
  max     => 10000000,
  ds_name => 'value',
}

class { 'collectd':
  typesdb      => [
    '/usr/share/collectd/types.db',
    $typesdb,
  ],
}

##Limitations

See metadata.json for supported platforms

##Known issues

Some plugins will need two runs of Puppet to fully generate the configuration for collectd. See this issue.

##Development

Running tests

This project contains tests for rspec-puppet.

Quickstart:

gem install bundler
bundle install
bundle exec rake lint
bundle exec rake validate
bundle exec rake spec SPEC_OPTS='--format documentation'

Version scoping

Some plugins or some options in plugins are only available for recent versions of collectd.

This module shall not use unsupported configuration directives. Look at templates/loadplugin.conf.erb for a hands-on example.

Please make use of the search by branch/tags on the collectd github to see when a function has been first released.

Reading the collectd.conf.pod file is good, validating the presence of the code in the .c files is even better.
