The ceilometer module is part of OpenStack, an effort by the OpenStack infrastructure team to provice continuous integration testing and code review for OpenStack and OpenStack community projects as part of the core software. The module itself is used to flexibly configure and manage the metering service for OpenStack.

The ceilometer module is an attempt to make Puppet capable of managing the entirety of ceilometer. This includes manifests to provision the ceilometer api, agents, and database stores. A ceilometer_config type is supplied to assist in the manipulation of configuration files.

What the ceilometer module affects

• Ceilometer, the metering service for OpenStack

puppet module install openstack/ceilometer

To utilize the ceilometer module's functionality you will need to declare multiple resources. The following is a modified excerpt from the [openstack module](httpd://github.com/stackforge/puppet -openstack). This is not an exhaustive list of all the components needed. We recommend that you consult and under stand the openstack module and the [core](http://d ocs.openstack.org) documentation to assist you in understanding the available deployment options.

class { '::ceilometer':
  metering_secret     => 'secrete',
  rabbit_userid       => 'ceilometer',
  rabbit_password     => 'an_even_bigger_secret',
  rabbit_host         => '127.0.0.1',
}
class { '::ceilometer::client': }
class { '::ceilometer::collector': }
class { '::ceilometer::expirer': }
class { '::ceilometer::alarm::evaluator': }
class { '::ceilometer::alarm::notifier': }
class { '::ceilometer::agent::central': }
class { '::ceilometer::agent::notification': }
class { '::ceilometer::api':
  enabled               => true,
  keystone_password     => 'a_big_secret',
  keystone_identity_uri => 'http://127.0.0.1:35357/',
}

ceilometer is a combination of Puppet manifests and Ruby code to deliver configuration and extra functionality through types and providers.

The ceilometer_config provider is a children of the ini_setting provider. It allows one to write an entry in the /etc/ceilometer/ceilometer.conf file.

ceilometer_config { 'DEFAULT/verbose' :
  value => true,
}

This will write verbose=true in the [DEFAULT] section.

Section/setting name to manage from ceilometer.conf

The value of the setting to be defined.

Whether to hide the value from Puppet logs. Defaults to false.

If value is equal to ensure_absent_val then the resource will behave as if ensure => absent was specified. Defaults to <SERVICE DEFAULT>

• The ceilometer modules have only been tested on RedHat and Ubuntu family systems.

This module has beaker-rspec tests

To run:

shell bundle install bundle exec rspec spec/acceptance
