Ceilometer no longer requires its own database since metric/event
storage was offloaded to Gnocchi/Panko. These implementations were
formally deprecated during the previous cycle[1] so can be removed.
This also updates the outdated example manifests to adapt to
the removal and the recent refactoring.

Overview
|
|
--------
|
|
|
|
The ceilometer module is part of [OpenStack](https://opendev.org/openstack), an effort by the
|
|
OpenStack infrastructure team to provide 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.
|
|

**What the ceilometer module affects**
|
|
|

|
|
|
|
### 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](https://docs.openstack.org) documentation to assist you in understanding the available deployment options.
|
|
|
|
```puppet
|
|
class { 'ceilometer':
|
|
telemetry_secret => 'secrete',
|
|
default_transport_url => 'rabbit://ceilometer:an_even_bigger_secret@127.0.0.1:5672',
|
|
}
|
|
class { 'ceilometer::keystone::auth':
|
|
password => 'a_big_secret',
|
|
}
|
|
class { 'ceilometer::collector': }
|
|
class { 'ceilometer::agent::polling': }
|
|
class { 'ceilometer::agent::notification': }
|
|
class { 'ceilometer::db::sync': }
|
|
class { 'ceilometer::keystone::authtoken':
|
|
password => 'a_big_secret',
|
|
auth_url => 'http://127.0.0.1:5000/',
|
|
}
|
|
```
|
|
|
|
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.
|
|
|
|
```puppet
|
|
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.
