OpenStack Icehouse : Ceilometer 利用方法2015/02/06 |
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 | +--------------------+ |
[1] | Ceilometer の設定#1, Ceilometer の設定#2, Ceilometer の設定#3 の各ノードの設定が完了した状態で以下のコマンドを入力すると、設定に問題なければ以下のように結果が返ってきます。 |

[2] | ここまでの設定で、Compute Service(Nova)の監視が可能な状態となっています。インスタンスを作成して起動した後、再度 meter-list を見ると、以下のように取得されたメーターを確認することができます。 |
