Grafana est une application open source multiplateforme permettant de représenter graphiquement des données provenant de différentes sources de données telles que InfluxDB, MySQL, PostgreSQL ou Prometheus. Aujourd’hui, je montre comment installer un service Grafana sur le diskstation Synology.

Étape 1 : Préparer Synology

La première chose à faire est d’activer le login SSH sur le Diskstation. Pour cela, il faut aller dans le “Panneau de configuration” > “Terminal”.


Ensuite, on peut se connecter via “SSH”, le port indiqué et le mot de passe de l’administrateur (les utilisateurs de Windows utilisent Putty ou WinSCP).

Je me connecte via Terminal, winSCP ou Putty et je laisse cette console ouverte pour plus tard.

Etape 2 : Créer un dossier Grafana

Je crée un nouveau répertoire appelé “grafana” dans le répertoire Docker.


Avec la commande “cd”, je recherche le répertoire Grafana :
x
–
+
Terminal

$ cd /volume1/docker/grafana/

Ensuite, j’y crée un fichier “grafana.yml” dans le répertoire Grafana avec ce contenu :

version: "2"
services:
  grafana:
    image: grafana/grafana
    container_name: grafana_server_grafana
    restart: always
    ports:
      - 3000:3000
    networks:
      - grafana
    environment:
      - GF_SERVER_CERT_FILE=/etc/ssl/server.crt
      - GF_SERVER_CERT_KEY=/etc/ssl/server.key
      - GF_SERVER_PROTOCOL=https
      - GF_SERVER_HTTP_PORT=3000
    volumes:
      - ./grafana:/var/lib/grafana
      - ./ssl:/etc/ssl

  influxdb:
    image: influxdb
    container_name: grafana_server_influxdb
    restart: always
    ports:
      - 8086:8086
    networks:
      - grafana
    volumes:
      - ./influxdb:/var/lib/influxdb
      - ./ssl:/etc/ssl
    environment:
      - INFLUXDB_DB=telegraf
      - INFLUXDB_USER=telegraf
      - INFLUXDB_USER_PASSWORD=influxdb-password
      - INFLUXDB_ADMIN_ENABLED=true
      - INFLUXDB_ADMIN_USER=admin
      - INFLUXDB_ADMIN_PASSWORD=influxdb-password
      - INFLUXDB_HTTP_HTTPS_ENABLED=true
      - INFLUXDB_HTTP_HTTPS_CERTIFICATE=/etc/ssl/server.crt
      - INFLUXDB_HTTP_HTTPS_PRIVATE_KEY=/etc/ssl/server.key
      - INFLUXDB_HTTP_AUTH_ENABLED=true

  telegraf:
    image: telegraf
    container_name: grafana_server_telegraf
    restart: always
    environment:
      HOST_PROC: /rootfs/proc
      HOST_SYS: /rootfs/sys
      HOST_ETC: /rootfs/etc
    volumes:
     - ./telegraf.conf:/etc/telegraf/telegraf.conf:ro
     - /var/run/docker.sock:/var/run/docker.sock:ro
     - /sys:/rootfs/sys:ro
     - /proc:/rootfs/proc:ro
     - /etc:/rootfs/etc:ro

networks:
  grafana:

Je crée encore deux sous-dossiers pour les données :

x
–
+
Terminal

$ mkdir grafana
$ mkdir influxdb
$ chown -R 472:472 grafana

Comme je veux utiliser SSL pour Grafana et l’interface correspondante, il faut encore créer un certificat :
x
–
+
Terminal

$ mkdir ssl
$ openssl genrsa -aes256 -passout pass:your-password -out ssl/server.pass.key 4096
$ openssl rsa -passin pass:your-password -in ssl/server.pass.key -out ssl/server.key
$ openssl req -new -key ssl/server.key -out ssl/server.csr
$ rm ssl/server.pass.key
$ openssl x509 -req -sha256 -days 365 -in ssl/server.csr -signkey ssl/server.key -out ssl/server.crt

En dernier lieu, je crée un fichier “telegraf.conf” avec ce contenu :

Maintenant, démarre le serveur Grafana avec cet appel Compose :

x
–
+
Terminal

$ sudo docker-compose -f grafana.yml up

Étape 3 : Configuration

Je peux maintenant appeler le serveur, configurer la base de données, créer un tableau de bord et connecter d’autres données de mesure.
