OpenStack Telemetry is an API service that provides a collector and a range of disparate agents. Before you can install these agents on nodes such as the compute node, you must use this procedure to install the core components on the controller node. Install the Telemetry Service on the controller node: # apt-get install ceilometer-api ceilometer-collector ceilometer-agent-central python-ceilometerclient # yum install openstack-ceilometer-api openstack-ceilometer-collector openstack-ceilometer-central python-ceilometerclient # zypper install openstack-ceilometer-api openstack-ceilometer-collector openstack-ceilometer-agent-central python-ceilometerclient Respond to the prompts for [keystone_authtoken] settings, RabbitMQ credentials and API endpoint registration. The Telemetry Service uses a database to store information. Specify the location of the database in the configuration file. The examples use a MongoDB database on the controller node: # yum install mongodb-server mongodb # zypper install mongodb # apt-get install mongodb Configure MongoDB to make it listen on the controller public IP address. Edit the /etc/mongodb.conf file and modify the bind_ip key: bind_ip = 192.168.0.10 Restart the MongoDB service to apply the configuration change: # service mongodb restart Start the MongoDB server and configure it to start when the system boots: # systemctl start mongodb.service # systemctl enable mongodb.service # service mongod start # chkconfig mongod on Create the database and a ceilometer database user: # mongo > use ceilometer > db.addUser( { user: "ceilometer", pwd: "CEILOMETER_DBPASS", roles: [ "readWrite", "dbAdmin" ] } ) Configure the Telemetry Service to use the database: # openstack-config --set /etc/ceilometer/ceilometer.conf \ database connection mongodb://ceilometer:CEILOMETER_DBPASS@controller:27017/ceilometer Edit the /etc/ceilometer/ceilometer.conf file and change the [database] section: ... [database] ... # The SQLAlchemy connection string used to connect to the # database (string value) connection = mongodb://ceilometer:CEILOMETER_DBPASS@controller:27017/ceilometer ... You must define an secret key that is used as a shared secret among Telemetry Service nodes. Use openssl to generate a random token and store it in the configuration file: # ADMIN_TOKEN=$(openssl rand -hex 10) # echo $ADMIN_TOKEN # openstack-config --set /etc/ceilometer/ceilometer.conf publisher_rpc metering_secret $ADMIN_TOKEN For SUSE Linux Enterprise, run the following command: # ADMIN_TOKEN=$(openssl rand 10|hexdump -e '1/1 "%.2x"') # openssl rand -hex 10 Edit the /etc/ceilometer/ceilometer.conf file and change the [publisher_rpc] section. Replace ADMIN_TOKEN with the results of the openssl command: ... [publisher_rpc] ... # Secret value for signing metering messages (string value) metering_secret = ADMIN_TOKEN ... Configure the RabbitMQ access: # openstack-config --set /etc/ceilometer/ceilometer.conf DEFAULT rabbit_host controller # openstack-config --set /etc/ceilometer/ceilometer.conf DEFAULT rabbit_password RABBIT_PASS Edit the /etc/ceilometer/ceilometer.conf file and update the [DEFAULT] section. rabbit_host = controller rabbit_password = RABBIT_PASS Create a ceilometer user that the Telemetry Service uses to authenticate with the Identity Service. Use the service tenant and give the user the admin role: # keystone user-create --name=ceilometer --pass=CEILOMETER_PASS --email=ceilometer@example.com # keystone user-role-add --user=ceilometer --tenant=service --role=admin Add the credentials to the configuration files for the Telemetry Service: # openstack-config --set /etc/ceilometer/ceilometer.conf keystone_authtoken auth_host controller # openstack-config --set /etc/ceilometer/ceilometer.conf keystone_authtoken admin_user ceilometer # openstack-config --set /etc/ceilometer/ceilometer.conf keystone_authtoken admin_tenant_name service # openstack-config --set /etc/ceilometer/ceilometer.conf keystone_authtoken auth_protocol http # openstack-config --set /etc/ceilometer/ceilometer.conf keystone_authtoken admin_password CEILOMETER_PASS Edit the /etc/ceilometer/ceilometer.conf file and change the [keystone_authtoken] section: [keystone_authtoken] auth_host = controller auth_port = 35357 auth_protocol = http admin_tenant_name = service admin_user = ceilometer admin_password = CEILOMETER_PASS Register the Telemetry Service with the Identity Service so that other OpenStack services can locate it. Use the keystone command to register the service and specify the endpoint: # keystone service-create --name=ceilometer --type=metering \ --description="Ceilometer Telemetry Service" Note the id property that is returned for the service. Use it when you create the endpoint: # keystone endpoint-create \ --service-id=the_service_id_above \ --publicurl=http://controller:8777/ \ --internalurl=http://controller:8777/ \ --adminurl=http://controller:8777/ Restart the services with their new settings: # service ceilometer-agent-central restart # service ceilometer-api restart # service ceilometer-collector restart Start the openstack-ceilometer-api, openstack-ceilometer-agent-centralopenstack-ceilometer-central and openstack-ceilometer-collector services and configure them to start when the system boots: # service openstack-ceilometer-api start # service openstack-ceilometer-agent-central start # service openstack-ceilometer-collector start # chkconfig openstack-ceilometer-api on # chkconfig openstack-ceilometer-agent-central on # chkconfig openstack-ceilometer-collector on # service openstack-ceilometer-api start # service openstack-ceilometer-central start # service openstack-ceilometer-collector start # chkconfig openstack-ceilometer-api on # chkconfig openstack-ceilometer-central on # chkconfig openstack-ceilometer-collector on
