==================
Ceilometer Formula
==================

The ceilometer project aims to deliver a unique point of contact for billing
systems to acquire all of the measurements they need to establish customer
billing, across all current OpenStack components with work underway to
support future OpenStack components.
This formula provides different backends for Ceilometer data: MongoDB, InfluxDB. Also,
Graphite and direct (to Elasticsearch) publishers are available. If InfluxDB is used
as a backend, heka is configured to consume messages from RabbitMQ and write in to
InfluxDB, i.e. ceilometer collector service is not used in this configuration.

Sample Pillars
==============

Ceilometer API/controller node
------------------------------

.. code-block:: yaml

    ceilometer:
      server:
        enabled: true
        version: mitaka
        cluster: true
        secret: pwd
        bind:
          host: 127.0.0.1
          port: 8777
        identity:
          engine: keystone
          host: 127.0.0.1
          port: 35357
          tenant: service
          user: ceilometer
          password: pwd
        message_queue:
          engine: rabbitmq
          host: 127.0.0.1
          port: 5672
          user: openstack
          password: pwd
          virtual_host: '/openstack'

Configuration of policy.json file
---------------------------------

.. code-block:: yaml

    ceilometer:
      server:
        ....
        policy:
          segregation: 'rule:context_is_admin'
          # Add key without value to remove line from policy.json
          'telemetry:get_resource':

Databases configuration
-----------------------

          - host: 10.0.106.20
            port: 27017
          - host: 10.0.106.30

            password: password
            database: ceilometer
          elasticsearch:

          - host: 10.0.106.20
          - host: 10.0.106.30

            enabled: true
            host: 10.0.0.1
            port: 2003

Ceilometer compute agent
