OpenStack Juno : Ceilometer 利用方法2015/02/07 |
|
OpenStack Metering Service（Ceilometer）の利用方法です。
ここでは例として以下のような環境を構築しています。
|
+------------------+ | +------------------------+
| [ Control Node ] | | | [ Network Node ] |
| Keystone |10.0.0.30 | 10.0.0.50| DHCP,L3,L2 Agent |
| Glance |------------+------------| Metadata Agent |
| Nova API |eth0 | eth0| Ceilometer Services |
| Neutron Server | | | |
+------------------+ | +------------------------+
eth0|10.0.0.51
+--------------------+
| [ Compute Node ] |
| Nova Compute |
| L2 Agent |
| Ceilometer-Compute |
