Puppet module for configuring collectd and plugins.
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 coverge. See Puppet needs two runs to correctly write my conf, why? below.
Hiera example in YAML of passing install_options to the package resouce for managing the collectd package. This parameter must be an array.
collectd::package_install_options:
- '--nogpgcheck'
Example of how to load plugins with no additional configuration:
collectd::plugin { 'battery': }
where 'battery' is the name of the plugin.
Parameters will vary widely between plugins. See the collectd documentation for each plugin for configurable attributes.

The filter plugin implements the powerful filter configuration of collectd. For further details have a look on the collectd manpage.
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.
class { 'collectd::plugin::filter':
ensure => 'present',
precachechain => 'PreChain',
postcachechain => 'PostChain',
}
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,

options => {
'Plugin' => '^mysql',

collectd::plugin::filter::target{ "1_prechain_jump_${chainname}":
chain => 'PreChain',
plugin => 'jump',
options => {
'Chain' => $chainname,

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

####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 byroot
(andchmod 0750
). If you don't specify anymodulepaths
a default value for given distribution will be used.modules
a Hash containing configuration of Python modules, where the key is the module nameglobals
Unlike most other plugins, this one should setGlobals 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
whentrue
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',

}
}
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"
}

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 { $db:
mode => '0644',
}
##Limitations
See metadata.json for supported platforms
##Known issues
###Puppet needs two runs to correctly write my conf, why?
Some plugins will need two runs of Puppet to fully generate the configuration for collectd. See this issue.
This can be avoided by specifying an explicit version ($version
) or a minimum version ($minimum_version
) for the collectd class. e.g. Setting either of these 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
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'
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.
