Installing the Compute Agent
|

============================

|

double: installing; compute agent
|
||||
|
||||
.. note:: The compute agent must be installed on each nova compute node.
|

|
||||
1. Configure nova.
|
||||
|
||||
The ``nova`` compute service needs the following configuration to
|
||||
be set in ``nova.conf``::
|
||||
|
||||
# nova-compute configuration for ceilometer
|
||||
instance_usage_audit=True

||||
|

5. Edit ``/etc/ceilometer/ceilometer.conf``
|
||||
|
||||
1. Configure RPC
|
||||
|
||||
Set the RPC-related options correctly so ceilometer's daemons
|
||||
can communicate with each other and receive notifications from
|
||||
the other projects.
|
||||
|
||||
In particular, look for the ``*_control_exchange`` options and
|
||||
make sure the names are correct. If you did not change the
|
||||
``control_exchange`` settings for the other components, the
|
||||
defaults should be correct.
|
||||
|
||||
.. note::
|
||||
|
||||
Ceilometer makes extensive use of the messaging bus, but has
|
||||
not yet been tested with ZeroMQ. We recommend using Rabbit or
|
||||
qpid for now.
|
||||
|
||||
2. Set the ``telemetry_secret`` value.
|
||||
|
||||
Set the ``telemetry_secret`` value to a large, random, value. Use
|
||||
the same value in all ceilometer configuration files, on all
|
||||
nodes, so that messages passing between the nodes can be
|
||||
validated.
|
||||
|
||||
Refer to :doc:`/configuration` for details about any other options
|
||||
you might want to modify before starting the service.

The default development configuration of the agent logs to

||||
stderr, so you may want to run this step using a screen session
|

or other tool for maintaining a long-running program in the

background.
