OpenStack Telemetry Service (Ceilometer) の利用方法です。 当例では以下のような環境を例に Ceilometer サービスをインストールしています。 ------------+--------------------------+--------------------------+------------ | | | 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] | Image サービスの各種データ収集を有効にするには、Glance を以下のように設定します。 |
[root@dlp ~(keystone)]#
vi /etc/glance/glance-api.conf # 最終行へ追記 [oslo_messaging_notifications] driver = messagingv2 # RabbitMQ 接続情報 transport_url = rabbit://openstack:password@dlp.srv.world systemctl restart openstack-glance-api |
