Overview

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.

Module Description

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.

Setup

What the ceilometer module affects

• Ceilometer, the metering service for OpenStack

Installing ceilometer

puppet module install openstack/ceilometer

Beginning with ceilometer

To utilize the ceilometer module's functionality you will need to declare multiple resources. This is not an exhaustive list of all the components needed. We recommend that you consult and understand the core openstack documentation to assist you in understanding the available deployment options.

class { '::ceilometer':
  telemetry_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::agent::central': }
class { '::ceilometer::agent::notification': }
class { '::ceilometer::db': }
class { '::ceilometer::api':
  enabled               => true,
  keystone_password     => 'a_big_secret',
  keystone_identity_uri => 'http://127.0.0.1:35357/',
}

Implementation

ceilometer

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

Types

ceilometer_config

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/http_timeout' :
  value => 600,
}

This will write http_timeout=600 in the [DEFAULT] section.

name

Section/setting name to manage from ceilometer.conf

value

The value of the setting to be defined.

secret

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

ensure_absent_val

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

Limitations

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

Beaker-Rspec

This module has beaker-rspec tests

To run:

shell bundle install bundle exec rspec spec/acceptance
