Grafana ist eine plattformübergreifende Open-Source-Anwendung zur grafischen Darstellung von Daten aus verschiedenen Datenquellen wie z. B. InfluxDB, MySQL, PostgreSQL oder Prometheus. Heute zeige ich, wie man einen Grafana-Dienst auf der Synology-Diskstation installiert.

Schritt 1: Synology vorbereiten

Als erstes muss der SSH-Login auf der Diskstation aktiviert werden. Dazu geht man in die „Systemsteuerung“ > „Terminal & SNMP“ und aktiviert dort die „SSH-Dienst aktivieren“-Einstellung.


Danach kann man sich via „SSH„, den angegebenen Port und den Administrator-Password anmelden (Windows-Nutzer nehmen Putty oder WinSCP).


Ich logge mich via Terminal, winSCP oder Putty ein und lasse diese Konsole für später offen.

Schritt 2: Grafana-Ordner erstellen

Ich erstelle ein neues Verzeichnis namens „grafana“ im Docker-Verzeichnis.


Mit dem Befehl “cd” suche ich das Grafana-Verzeichnis auf:

x
–
+
Terminal

$ cd /volume1/docker/grafana/

Dann erstelle ich dort eine „grafana.yml“-Datei im Grafana-Verzeichnis mit diesem Inhalt:

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:

Ich erstelle noch zwei Unterordner für die Daten:

x
–
+
Terminal

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

Da ich für Grafana und die dazugehörigen Schnittstelle SSL nutzen will, muss noch ein Zertifikat erstellt werden:

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

Siehe:

Als Letztes erstelle ich eine “telegraf.conf”-Datei mit diesem Inhalt:

Terminal

$ sudo docker-compose -f grafana.yml up

Schritt 3: Konfiguration

Nun kann ich den Server aufrufen, die Datenbank konfigurieren, Dashboard erstellen und weitere Messdaten anschliessen.
