OpenStack Epoxy : Configure Ceilometer (Network Node)

Install OpenStack Telemetry Service (Ceilometer). This example is based on the environment like follows. ------------+--------------------------+--------------------------+------------ | | | eth0|10.0.0.30 eth0|10.0.0.50 eth0|10.0.0.51 +-----------+-----------+ +-----------+-----------+ +-----------+-----------+ | [ dlp.srv.world ] | | [ network.srv.world ] | | [ node01.srv.world ] | | (Control Node) | | (Network Node) | | (Compute Node) | | | | | | | | MariaDB RabbitMQ | | Open vSwitch | | Libvirt | | Memcached Nginx | | Neutron Server | | Nova Compute | | Keystone httpd | | OVN-Northd | | Open vSwitch | | Glance Nova API | | Nginx iSCSI Target | | OVN Metadata Agent | | Cinder API | | Cinder Volume | | OVN-Controller | | | | Gnocchi httpd | | Ceilometer Compute | | | | Ceilometer Central | | | +-----------------------+ +-----------------------+ +-----------------------+

[1]	Install Gnocchi first, refer to here.
[2]	Add users and others for Ceilometer in Keystone.

[3]	Install Ceilometer services on Network Node.

root@network:~#  apt -y install ceilometer-agent-central ceilometer-agent-notification

[4]	Configure Ceilometer.
