Configure Ceilometer Compute on Compute Node on this section.
[1] Install Ceilometer Compute and so on.
# install from RDO, EPEL

[root@node01 ~]#
yum --enablerepo=openstack-icehouse,epel -y install openstack-ceilometer-compute python-ceilometer python-ceilometerclient
[2] Configure Nova Compute.
[root@node01 ~]#
vi /etc/nova/nova.conf
# add follows in the "[DEFAULT]" section

instance_usage_audit=True
instance_usage_audit_period=hour
notify_on_state_change=vm_and_task_state
notification_driver=nova.openstack.common.notifier.rpc_notifier
notification_driver=ceilometer.compute.nova_notifier
[root@node01 ~]#
/etc/rc.d/init.d/openstack-nova-compute restart

[3] Configure Ceilometer Compute.
[root@node01 ~]#
mv /etc/ceilometer/ceilometer.conf /etc/ceilometer/ceilometer.conf.org

[root@node01 ~]#
vi /etc/ceilometer/ceilometer.conf
# create new

[DEFAULT]
# RabbitMQ server

rabbit_host=10.0.0.30

[root@node01 ~]#
chgrp ceilometer /etc/ceilometer/ceilometer.conf

[root@node01 ~]#
chmod 640 /etc/ceilometer/ceilometer.conf

[root@node01 ~]#
/etc/rc.d/init.d/openstack-ceilometer-compute start

[root@node01 ~]#
chkconfig openstack-ceilometer-compute on
