Install and Configure OpenStack Telemetry Metering Service (Ceilometer)
Based on OpenStack Icehouse releasewe will install Telemetry service on controller node
1. yum -y install openstack-ceilometer-api openstack-ceilometer-collector openstack-ceilometer-notification openstack-ceilometer-central openstack-ceilometer-alarm python-ceilometerclient
2. mysql -uroot -p
mysql> create database ceilometer;
mysql> grant all privileges on ceilometer.* to 'ceilometer'@'localhost' identified by 'CEILOMETER-DBPASS';
mysql> grant all privileges on ceilometer.* to 'ceilometer'@'%' identified by 'CEILOMETER-DBPASS';
mysql> flush privileges;
3. vi /etc/ceilometer/ceilometer.conf
connection=mysql://ceilometer:ceilometer@MYSQL-SERVER/ceilometer
ceilometer-dbsync
4. # create ceilometer user
keystone user-create --tenant service --name ceilometer --pass CEILOMETER-USER-PASS
# Add role to the ceilometer user
keystone user-role-add --user=ceilometer --tenant=service --role=admin
# create ceilometer service
keystone service-create --name=ceilometer --type=metering --description="Telemetry Service"
# create ceilometer endpoint
keystone endpoint-create --region RegionOne --service ceilometer --publicurl=http://controller:8777 --internalurl=http://controller:8777 --adminurl=http://controller:8777
5. vi /etc/ceilometer/ceilometer.conf
metering_secret=SECRET-STRING-YOU-SPECIFY
rpc_backend=ceilometer.openstack.common.rpc.impl_qpid
qpid_hostname=controller
auth_strategy=keystone
auth_host = controller
auth_port = 35357
auth_protocol = http
auth_uri = http://controller:5000
admin_tenant_name = service
admin_user = ceilometer
admin_password = CEILOMETER-USER-PASSWORD
os_username=ceilometer
os_password=CEILOMETER-USER-PASSWORD
os_tenant_name=service
os_auth_url=http://controller:5000/v2.0
6. chown -R ceilometer:ceilometer /etc/ceilometer /var/log/ceilometer
for service in api notification central collector alarm-evaluator alarm-notifier; do
service openstack-ceilometer-$service start
chkconfig openstack-ceilometer-$service on
done
Install the Compute agent for Telemetry on computer node
1. yum -y install openstack-ceilometer-compute python-ceilometerclient python-pecan
2. vi /etc/nova/nova.conf
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
service openstack-nova-compute restart
3. vi /etc/ceilometer/ceilometer.conf
metering_secret=SECRET-STRING-YOU-SPECIFY
rpc_backend=ceilometer.openstack.common.rpc.impl_qpid
qpid_hostname = controller
auth_host = controller
auth_port = 35357
auth_protocol = http
auth_uri = http://controller:5000
admin_tenant_name = service
admin_user = ceilometer

os_username=ceilometer
os_password=CEILOMETER-USER-PASSWORD
os_tenant_name=service
os_auth_url=http://controller:5000/v2.0
4. chown -R ceilometer:ceilometer /etc/ceilometer /var/log/ceilometer
service openstack-ceilometer-compute start; chkconfig openstack-ceilometer-compute on
Configure the Image Service for Telemetry
on Glance Image Service node
1. vi /etc/glance/glance-api.conf
notification_driver=messaging
2. service openstack-glance-api restart; service openstack-glance-registry restart
Config the Block Storage service agent for Telemetry
on the cinder controller and volume nodes
vi /etc/cinder/cinder.conf
control_exchange=cinder
notification_driver=cinder.openstack.common.notifier.rpc_notifier
On the cinder controller node:
service openstack-cinder-api restart; service openstack-cinder-scheduler restart
On the cinder volume node:
service openstack-cinder-volume restart
Configure the Object Storage service for Telemetry
on keystone node:
keystone role-create --name=ResellerAdmin
keystone user-role-add --tenant service --user ceilometer --role ResellerAdmin
on swift proxy node:
vi /etc/swift/proxy-server.conf
# include ceilometer
pipeline = healthcheck cache authtoken keystoneauth ceilometer proxyserver
# add at the last line
use = egg:ceilometer#swift
service openstack-swift-proxy restart
