``` * Grant proper access to the grafana database: ``` GRANT ALL PRIVILEGES ON grafana.* TO 'novaadmin'@'localhost' IDENTIFIED BY 'openstack'; GRANT ALL PRIVILEGES ON grafana.* TO 'novaadmin'@'%' IDENTIFIED BY 'openstack'; ``` * Edit /etc/grafana/grafana.ini file: ``` [database] type = mysql host = 10.50.2.10:3306 name = grafana user = novaadmin password = openstack ``` * Service restart ``` # service grafana-server restart ``` * Configure **keystone.conf** and **gnocchi.conf** ``` [cors] allowed_origin = http://10.50.2.10:3000 ``` * Service restart ``` # service apache2 restart # service gnocchi-metricd restart ``` * Installation gnocchi-datasource via grafana.net ``` sudo grafana-cli plugins install gnocchixyz-gnocchi-datasource ``` * Restart Grafana by running: ``` # service grafana-server restart ``` * Access grafana dashboard: ``` # http://grafana_host:3000 ``` Dashboard 帳密皆admin ![](https://1123223527-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-L_BW8-pFxbu7PCB6NXf%2Fuploads%2Fgit-blob-5ca53f4f173bf3c3ebf1f53a00714c06306dcb96%2Fgrafana_dash.jpg?alt=media) 登入後點選 create data source後，Type選擇gnocchi，之後設定依照下圖:\ [![](http://10.50.0.12/wiki/lib/exe/fetch.php?w=600\&tok=4ceb75\&media=project:openstack:opentack_auto_scaling:grafana_gnocchi.jpg)](http://10.50.0.12/wiki/lib/exe/detail.php?id=project%3Aopenstack%3Aopentack_auto_scaling%3Agrafana\&media=project:openstack:opentack_auto_scaling:grafana_gnocchi.jpg) ![](https://1123223527-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-L_BW8-pFxbu7PCB6NXf%2Fuploads%2Fgit-blob-c3c02960f49e033917d78156c102fe58db538eb8%2Fgrafana_gnocchi.jpg?alt=media) 設定完後，至左邊工具列點選 create→dashboard，選擇圖表類型，這裡使用Graph\ [![](http://10.50.0.12/wiki/lib/exe/fetch.php?w=600\&tok=462c17\&media=project:openstack:opentack_auto_scaling:grafana_add.jpg)](http://10.50.0.12/wiki/lib/exe/detail.php?id=project%3Aopenstack%3Aopentack_auto_scaling%3Agrafana\&media=project:openstack:opentack_auto_scaling:grafana_add.jpg) ![](https://1123223527-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-L_BW8-pFxbu7PCB6NXf%2Fuploads%2Fgit-blob-e43658fbeb30ca59429b2fa0360677c364ae7f8f%2Fgrafana_add.jpg?alt=media) 新增後，點選上方Panel Title→ edit\ [![](http://10.50.0.12/wiki/lib/exe/fetch.php?w=600\&tok=2c33ac\&media=project:openstack:opentack_auto_scaling:grafana_edit.jpg)](http://10.50.0.12/wiki/lib/exe/detail.php?id=project%3Aopenstack%3Aopentack_auto_scaling%3Agrafana\&media=project:openstack:opentack_auto_scaling:grafana_edit.jpg) ![](https://1123223527-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-L_BW8-pFxbu7PCB6NXf%2Fuploads%2Fgit-blob-0f2c8ec08e5685bdbd62bfb8eafd3cdd01feae73%2Fgrafana_edit.jpg?alt=media) 根據下圖設定，**query的original*****resource*****id為VM的ID**，**Metric name為要監測項目**，\ **Aggregator為顯示值得方式(平均、最大等等)**，**Granularity為間隔時間**，**Label為圖表上摺線的名稱**，紅框處還可以設定更多，不贅述，下圖為VM的cpu使用率圖表: ![](https://1123223527-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-L_BW8-pFxbu7PCB6NXf%2Fuploads%2Fgit-blob-9871fcd97d07ca865ce8552f05fcd8012b223568%2Fgrafana_graph.jpg?alt=media) 最後新增完後的總覽: ![](https://1123223527-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-L_BW8-pFxbu7PCB6NXf%2Fuploads%2Fgit-blob-89bbd69ac9301cca2196b4a932dee8e307093a61%2Fgrafana_all.jpg?alt=media) 為了使用方便，可以直接 import 別人寫好的 dasboard，[可以在 grafana 官網搜尋](https://grafana.com/dashboards?dataSource=gnocchixyz-gnocchi-datasource\&panelType=graph\&search=openstack)，以下是我從官網找到的 **Openstack-Gnocchi instance metrics**，並修改監測 memory 參數後的 dashboard，[複製連結內的 json，點選 import 後，貼上 json，並選擇 load](https://github.com/dommgifer/config/blob/master/openstack-gnocchi-instance-metrics_rev1.json)。 ![](https://1123223527-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-L_BW8-pFxbu7PCB6NXf%2Fuploads%2Fgit-blob-a98f7dfc01dcd4ebdc51cc0d25da92b5133bbf4b%2Fimport.jpg?alt=media) 選擇 datasource 為 gnocchi import dashboard 完成，可以從紅框處選擇要查看的 VM ![](https://1123223527-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-L_BW8-pFxbu7PCB6NXf%2Fuploads%2Fgit-blob-520c7d779466c707e72a4d49a47275a41971c3ff%2Fvm-selector.jpg?alt=media)
