Telemetry uses a combination of notifications and an agent to collect Compute meters. Perform these steps on each compute node.
Install the packages:
# apt-get install ceilometer-agent-compute
# apt-get install ceilometer-agent-ipmi (optional)
Edit the /etc/ceilometer/ceilometer.conf
file and
complete the following actions:
In the [DEFAULT]
section, configure RabbitMQ
message queue access:
[DEFAULT]
...
transport_url = rabbit://openstack:RABBIT_PASS@controller
Replace RABBIT_PASS
with the password you chose for the
openstack
account in RabbitMQ
.
In the [service_credentials]
section, configure service
credentials:
[service_credentials]
...
auth_url = http://controller:5000
project_domain_id = default
user_domain_id = default
auth_type = password
username = ceilometer
project_name = service
password = CEILOMETER_PASS
interface = internalURL
region_name = RegionOne
Replace CEILOMETER_PASS
with the password you chose for
the ceilometer
user in the Identity service.
Edit the /etc/nova/nova.conf
file and configure
notifications in the [DEFAULT]
section:
[DEFAULT]
...
instance_usage_audit = True
instance_usage_audit_period = hour
notify_on_state_change = vm_and_task_state
[oslo_messaging_notifications]
...
driver = messagingv2
Note
To enable IPMI meters, ensure IPMITool is installed and the host supports Intel Node Manager.
Edit the /etc/sudoers
file and include:
.. code-block:: ini
ceilometer ALL = (root) NOPASSWD: /usr/bin/ceilometer-rootwrap /etc/ceilometer/rootwrap.conf *
Edit the /etc/ceilometer/polling.yaml
to include the required meters, for example:
.. code-block:: yaml
name: ipmi interval: 300 meters:
- hardware.ipmi.temperature
Restart the agent:
# service ceilometer-agent-compute restart
# service ceilometer-agent-ipmi restart (optional)
Restart the Compute service:
# service nova-compute restart
