Matthew Kassawara 5ee72cfa36 [install] Fix various minor problems 
Fix the following minor problems to reduce work after
stable/liberty branching:

1) RDO: Revert Python MySQL library from PyMySQL to MySQL-python
   due to lack of support for the former.
2) RDO: Explicitly install 'ebtables' and 'ipset' packages due
   to dependency problems.
3) General: Change numbered list to bulleted list for lists with
   only one item.
4) General: Restructure horizon content to match other services.
   More duplication of content, but sometimes RST conditionals
   are terrible and distro packages should use the same
   configuration files.
5) General: Restructure NoSQL content to match SQL content.
6) General: Improve clarity of NTP content.

Enable Compute service meters

Telemetry uses a combination of notifications and an agent to collect Compute meters. Perform these steps on each compute node.

Install and configure components

obs

  1. Install the packages:

    # zypper install openstack-ceilometer-agent-compute

rdo

  1. Install the packages:

    # yum install openstack-ceilometer-compute python-ceilometerclient python-pecan

ubuntu

  1. Install the packages:

    # apt-get install ceilometer-agent-compute
  1. Edit the /etc/ceilometer/ceilometer.conf file and complete the following actions:

    • In the [DEFAULT] and [oslo_messaging_rabbit] sections, configure RabbitMQ message queue access:

      [DEFAULT]
...
rpc_backend = rabbit

[oslo_messaging_rabbit]
...
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS

      Replace RABBIT_PASS with the password you chose for the openstack account in RabbitMQ.

    • In the [DEFAULT] and [keystone_authtoken] sections, configure Identity service access:

      [DEFAULT]
...
auth_strategy = keystone

[keystone_authtoken]
...
auth_uri = http://controller:5000
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = ceilometer
password = CEILOMETER_PASS

      Replace CEILOMETER_PASS with the password you chose for the Telemetry service database.

    • In the [service_credentials] section, configure service credentials:

      [service_credentials]
...
os_auth_url = http://controller:5000/v2.0
os_username = ceilometer
os_tenant_name = service
os_password = CEILOMETER_PASS
os_endpoint_type = internalURL
os_region_name = RegionOne

      Replace CEILOMETER_PASS with the password you chose for the ceilometer user in the Identity service.

    • (Optional) To assist with troubleshooting, enable verbose logging in the [DEFAULT] section:

      [DEFAULT]
...
verbose = True

Configure Compute to use Telemetry

  • 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
notification_driver = messagingv2

Finalize installation

obs

  1. Start the agent and configure it to start when the system boots:

    # systemctl enable openstack-ceilometer-agent-compute.service
# systemctl start openstack-ceilometer-agent-compute.service

rdo

  1. Start the agent and configure it to start when the system boots:

    # systemctl enable openstack-ceilometer-compute.service
# systemctl start openstack-ceilometer-compute.service

obs or rdo

  1. Restart the Compute service:

    # systemctl restart openstack-nova-compute.service

ubuntu

  1. Restart the agent:

    # service ceilometer-agent-compute restart

  2. Restart the Compute service:

    # service nova-compute restart
