Installing development sandbox
|
|
===============================
|
|
|
|
Ceilometer has several daemons. The basic are: :term:`polling agent` running
|
|
either on the Nova compute node(s) or :term:`polling agent` running on the
|
|
central management node(s), :term:`collector`
|
|
and :term:`notification agent` running on the cloud's management node(s).
|
|
In a development environment created by devstack_, these services are
|
|
typically running on the same server. They do not have to be, though, so some
|
|
of the instructions below are duplicated. Skip the steps you have already done.
|
|
|
|
.. note::
|
|
|
|
In fact, previously ceilometer had separated compute and central agents, and
|
|
their support is implemented in devstack_ right now, not one agent variant.
|
|
For now we do have deprecated cmd scripts emulating old compute/central
|
|
behavior using namespaces option passed to polling agent, which will be
|
|
maintained for a transitional period.
|
|
|
|
Configuring devstack
|
|
====================
|
|
|
|
.. index::
|
|
double: installing; devstack
|
|
|
|
1. Download devstack_.
|
|
|
|
2. Create a ``local.conf`` file as input to devstack.
|
|
|
|
3. Ceilometer makes extensive use of the messaging bus, but has not
|
|
yet been tested with ZeroMQ. We recommend using Rabbit for
|
|
now. By default, RabbitMQ will be used by devstack.
|
|
|
|
4. The ceilometer services are not enabled by default, so they must be
|
|
enabled in ``local.conf`` before running ``stack.sh``.
|
|
|
|
This example ``local.conf`` file shows all of the settings required for
|
|
ceilometer::
|
|
|
|
[[local|localrc]]
|
|
# Enable the Ceilometer devstack plugin
|
|
enable_plugin ceilometer https://git.openstack.org/openstack/ceilometer.git
|
|
|
|
5. Nova does not generate the periodic notifications for all known
|
|
instances by default. To enable these auditing events, set
|
|
``instance_usage_audit`` to true in the nova configuration file and restart
|
|
the service.
|
|
|
|
6. Cinder does not generate notifications by default. To enable
|
|
these auditing events, set the following in the cinder configuration file
|
|
and restart the service::
|
|
|
|
notification_driver=messagingv2
|
