Grafana, InfluxDB, MySQL, PostgreSQL veya Prometheus gibi çeşitli veri kaynaklarından gelen verileri grafiksel olarak görüntülemek için platformlar arası açık kaynaklı bir uygulamadır. Bugün Synology DiskStation üzerinde bir Grafana hizmetinin nasıl kurulacağını gösteriyorum.

Adım 1: Synology’yi Hazırlayın

İlk olarak, DiskStation üzerinde SSH oturum açma etkinleştirilmelidir. Bunu yapmak için, “Denetim Masası” > “Terminal


Ardından “SSH”, belirtilen bağlantı noktası ve yönetici parolası ile oturum açabilirsiniz (Windows kullanıcıları Putty veya WinSCP kullanır).

Terminal, winSCP veya Putty ile oturum açıyorum ve bu konsolu daha sonra kullanmak üzere açık bırakıyorum.

Adım 2: Grafana klasörü oluşturun

Docker dizininde “grafana” adında yeni bir dizin oluşturuyorum.


“cd” komutu ile Grafana dizinini arıyorum:
x
–
+
Terminal

$ cd /volume1/docker/grafana/

Ardından Grafana dizininde bu içeriğe sahip bir “grafana.yml” dosyası oluşturuyorum:

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:

Veriler için iki alt klasör daha oluşturuyorum:

x
–
+
Terminal

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

Grafana ve ilgili arayüz için SSL kullanmak istediğimden, yine de bir sertifika oluşturulması gerekiyor:
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

Bak:

Son olarak, bu içeriğe sahip bir “telegraf.conf” dosyası oluşturuyorum:

Şimdi bu Compose çağrısı ile Grafana sunucusunu başlatın:

x
–
+
Terminal

$ sudo docker-compose -f grafana.yml up

Adım 3: Yapılandırma

Artık sunucuyu çağırabilir, veritabanını yapılandırabilir, gösterge tablosu oluşturabilir ve daha fazla ölçüm verisi bağlayabilirim.
