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,
  minimum_version => '5.4',
}

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.

Specifying the version or minimum_version of collectd as shown above reduces the need for two puppet runs to converge. See Puppet needs two runs to correctly write my conf, why? below.

Hiera example in YAML of passing install_options to the package resource for managing the collectd package. This parameter must be an array.

collectd::package_install_options:
  - '--nogpgcheck'

Simple Plugins

Example of how to load plugins with no additional configuration:

collectd::plugin { 'battery': }

Where battery is the name of the plugin.

Note: this should only be done in the case of a class for the plugin not existing in this module.

Repo management

The module will enable a repo by default.

On CentOS that will be EPEL:

• http://rpms.famillecollet.com/rpmphp/zoom.php?rpm=collectd

On Ubuntu that'll be the CollectD PPA:

• https://launchpad.net/~collectd/+archive/ubuntu/collectd-5.5

Public key keyserver

In case you need to change the server where to download the public key from for whatever reason (AKA: server is down) you can use the parameter $package_keyserver

CI Packages

Recently, Collectd CI packages are also avaliable from the CI repo

More information is avaliable here:

• https://github.com/collectd/collectd-ci

You can choose the CI repo with the $ci_package_repo parameter.

$ci_package_repo has to match '5.4', '5.5', '5.6', '5.7' or 'master' (RC for next release) as these are the current branches being built in the Collectd CI.

Class: collectd::plugin::filter

The filter plugin implements the powerful filter configuration of collectd. For further details have a look on the collectd manpage.

Parameters

• ensure ("ensure","absent"): Ob absent it will remove all references of the filter plugins. Note: The Chain config needs to be purged by the chain define.
• precachechain (String): The Name of the default Pre Chain.
• postcachechain (String): The Name of the default Post Chain.

Examples

Overwrite default chains

class { 'collectd::plugin::filter':
    ensure          => 'present',
    precachechain   => 'PreChain',
    postcachechain  => 'PostChain',
}

Full Example

This Example will rename the hostname of the mysql plugin.

include collectd::plugin::filter

# define default chains with default target
collectd::plugin::filter::chain { 'PreChain':
    target => 'return'
}
collectd::plugin::filter::chain { 'PostChain':
    target => 'write'
}

# create a third chain,
$chainname = 'MyAweseomeChain'
collectd::plugin::filter::chain { $chainname:
    ensure => present,
    target => 'return'
}

# add a new rule to chain
$rulename = 'MyAweseomeRule'
collectd::plugin::filter::rule { $rulename:
    chain => $chainname,
}

# add a new match rule, match metrics of the mysql plugin
collectd::plugin::filter::match { "Match mysql plugin":
    chain   => $chainname,
    rule    => $rulename,
    plugin  => 'regex',
    options => {
        'Plugin' => '^mysql',
    }
}

#rewrite hostname
collectd::plugin::filter::target{ "overwrite hostname":
    chain   => $chainname,
    rule    => $rulename,
    plugin  => 'set',
    options => {
        'Host' => 'hostname.domain',
    },
}

# hook the configured chain in the prechain
collectd::plugin::filter::target{ "1_prechain_jump_${chainname}":
    chain   => 'PreChain',
    plugin  => 'jump',
    options => {
        'Chain' => $chainname,
    },
}

Define: collectd::plugin::filter::chain

This define will create a new chain, which is required by targets, matches and rules.

Parameters

• ensure ("ensure","absent"): When set to absent it will remove the chain with all assigned rules, targets and matches.
• target ('notification','replace','set','return','stop','write','jump'): Optional. Set default target if no target has been applied. Strongly recommend for default chains.
• target_options (Hash): If target is specified, pass optional hash to define.

Example

see collectd::plugin::filter above

Define: collectd::plugin::filter::rule

This define will add a new rule to a specific chain

Parameters

• chain (String): Assign to this chain.

Example

see collectd::plugin::filter above

Define: collectd::plugin::filter::target

This define will add a target to a chain or rule.

Parameters

• chain (String): Assign to this chain.
• plugin ('notification','replace','set','return','stop','write','jump'): The plugin of the target.
• options (Hash): Optional parameters of the target plugin.
• rule (String): Optional. Assign to this rule. If not present, target will be applied at the end of chain without rule matching.

Example

see collectd::plugin::filter above

Define: collectd::plugin::filter::match

This define will add a match rule.

Parameters

• chain (String): Assign to this chain.
• rule (String): Assign to this rule.

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'

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 provider is file. 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',

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

class { 'collectd::plugin::postgresql':
  databases => {
    'postgres' => {
      'host'     => '/var/run/postgresql/',
      'user'     => 'postgres',

  }
}

Class: collectd::plugin::powerdns

You can either specify powerdns servers / recursors at once:

class { 'collectd::plugin::powerdns':
  recursors => {
    'recursor1' => {
      'socket'  => '/var/run/my-socket',
      'collect' => ['cache-hits', 'cache-misses'],
    },
    'recursor2' => {}
  },
  servers => {
    'server1' => {
      'socket'  => '/var/run/my-socket',
      'collect' => ['latency', 'recursing-answers', 'recursing-questions'],
    }
  },
}

Or define single server / recursor:

collectd::plugin::powerdns::recursor { 'my-recursor' :
  socket  => '/var/run/my-socket',
  collect => ['cache-hits', 'cache-misses'],
}

collectd::plugin::powerdns::server { 'my-server' :
  socket  => '/var/run/my-socket',
  collect => ['latency', 'recursing-answers', 'recursing-questions'],
}

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 for details

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

Class: collectd::plugin::python

The plugin uses a fact python_dir to find the python load path for modules. python or python3 must be installed as a pre-requisite for the this fact to give a non-default value.

• 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)

• conf_name name of the file that will contain the python module configuration (default: python-config.conf)

  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",
     'Verbose' => true,
     'Values'  => ["abc","def"],
     'Name'    => 'My Name',
     'Limit'   => 4.5,
    }
  ]
}

The resulting configuration would be

Import "zk-collectd"
<Module "zk-collectd">
  Hosts "localhost:2181"
  Verbose true
  Values "abc" "def"
  Limit 4.5
</Module>

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",
     'Value' => 3.4,
    }
  ]
}

              'query' => 'DBSIZE',
          },
      },
    },
  }
}

Class: collectd::plugin::rabbitmq

Please note the rabbitmq plugin provides a types.db.custom. You will need to add this to collectd::config::typesdb via hiera or in a manifest. Failure to set the types.db.custom content will result in no metrics from the rabbitmq plugin.

The rabbitmq plugin has not been ported to python3 and will fail on CentOS 8 #75

Class: collectd::plugin::write_graphite

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

collectd::plugin::write_graphite::carbon {'my_graphite':
  graphitehost   => 'graphite.example.org',
  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    => '',

  escapecharacter   => '_',
  alwaysappendds    => true,
  storerates        => true,
  separateinstances => false,
  logsenderrors     => true

Class: collectd::plugin::write_http

The write_http plugin supports two ways of configuration, the old plugin format using urls:

class { 'collectd::plugin::write_http':
  urls => {
    'collect1.example.org' => { 'format' => 'JSON' },
    'collect2.example.org' => {},
  }
}

And the new plugin format using nodes:

class { 'collectd::plugin::write_http':
  nodes => {
    'collect1' => { 'url' => 'collect1.example.org', 'format' => 'JSON' },
    'collect2' => { 'url' => 'collect2.example.org'},
  }
}

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,
  ],
}

Other software may need to read the Collectd types database files. To allow non-root users to read from a collectd::typesdb file like so:

$db = '/etc/collectd/types.db'
collectd::typesdb { $db:
  mode => '0644',
}

Puppet Tasks

Assuming that the collectdctl command is available on remote nodes puppet tasks exist to run collectdctl and collect results from nodes. The tasks rely on python3 being available also.

Puppet Task collectd::listval

$ bolt task show collectd::listval
collectd::listval - Lists all available collectd metrics

USAGE:
bolt task run --nodes <node-name> collectd::listval
collectd::listval - Lists all available collectd metrics

USAGE:
bolt task run --nodes <node-name> collectd::listval

Puppet Task collectd::getval

$ bolt task show collectd::getval

collectd::getval - Get a particular metric for a host

USAGE:
bolt task run --nodes <node-name> collectd::getval metric=<value>

PARAMETERS:
- metric: String[1]
    Name of metric, e.g. load/load-relative

Example Task collectd::getval

$ bolt -u root task run collectd::getval metric=load/load-relative -n aiadm32.example.org

returns the values of the load metric.

  {
    "metric": "load/load-relative",
    "values": {
      "shortterm": "1.750000e-01",
      "longterm": "8.000000e-02",
      "midterm": "8.500000e-02"
    }
  }

Limitations

See metadata.json for supported platforms

Known issues

Puppet needs two runs to correctly write my conf, why?

Some plugins will need two runs of Puppet to fully generate the configuration for collectd. See this issue. This can be avoided by specifying a minimum version ($minimum_version) for the collectd class. e.g. Setting this to 1.2.3 will make this module assume on the first run (when the fact responsible to provide the collectd version is not yet available) that your systems are running collectd 1.2.3 and generate the configuration accordingly.

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 rubocop
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.
