Cấu hình Grafana lấy metric từ Gnocchi

  • In Grafana node, instal Gnocchi Datasource:
sudo grafana-cli plugins install gnocchixyz-gnocchi-datasource
service grafana-server restart
  • Grafana has 2 modes of operation: proxy or direct mode.

    • proxy: ở mode nĂ y, Grafana sẽ nhận request từ user, vĂ chuyển tá»›i Gnocchi. Grafana sẽ chỉ xĂ¡c thá»±c được vá»›i Gnocchi qua token được cung cấp sẵn, khi token hết hạn sẽ phải cấp lại, hoặc lá»±a chá»�n khĂ´ng xĂ¡c thá»±c Gnocchi vá»›i Keystone (kĂ©m bảo mật).

    • direct: ở mode nĂ y, user sẽ lĂ m việc trá»±c tiếp vá»›i Gnocchi, Grafana chỉ Ä‘Ă³ng vai trĂ² hiển thi. User sẽ xĂ¡c thá»±c vá»›i Keystone định kỳ, do Ä‘Ă³ bảo mật được thĂ´ng tin.

Use proxy mode

  • Configure a new datasource in Grafana with the Gnocchi URL. If you are using the Keystone middleware for authentication, you can also provide an authentication token.

enter image description here

(192.168.20.14: ip Gnocchi node)

Use direct mode

  • Configure the CORS middleware in file /etc/gnocchi/gnocchi.conf in Gnocchi node to allow request from Grafana.
[cors]
allowed_origin = http://192.168.10.170:3000
  • Restart apache2
service apache2 restart
  • Configure the CORS middleware in file /etc/keystone/keystone.conf in Controller node to allow request from Grafana too:
[cors]
allowed_origin = http://192.168.10.170:3000
  • Restart apache2
service apache2 restart
