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 |
                      +--------------------+

[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な結果が返ってきます。
[root@dlp ~(keystone)]#

+------------+-------+-------+--------------------------------------+---------+----------------------------------+
[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が確認できます。
[root@dlp ~(keystone)]#
Int_Net_ID=`neutron net-list | grep int_net | awk '{ print $2 }'`

[root@dlp ~(keystone)]#
