Grafana este o aplicație open source cross-platform pentru afișarea grafică a datelor din diverse surse de date, cum ar fi InfluxDB, MySQL, PostgreSQL sau Prometheus. Astăzi vă arăt cum să instalați un serviciu Grafana pe Synology DiskStation.

Pasul 1: Pregătiți Synology

În primul rând, conectarea SSH trebuie să fie activată pe DiskStation. Pentru a face acest lucru, mergeți la “Control Panel” > “Terminal”.


Apoi vă puteți conecta prin “SSH”, portul specificat și parola de administrator (utilizatorii de Windows folosesc Putty sau WinSCP).

Mă conectez prin Terminal, winSCP sau Putty și las această consolă deschisă pentru mai târziu.

Pasul 2: Creați folderul Grafana

Creez un nou director numit “grafana” în directorul Docker.


Cu comanda “cd” caut directorul Grafana:
x
–
+
Terminal

$ cd /volume1/docker/grafana/

Apoi creez un fișier “grafana.yml” în directorul Grafana cu acest conținut:

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:

Creez încă două subfoldere pentru date:

x
–
+
Terminal

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

Deoarece vreau să folosesc SSL pentru Grafana și interfața asociată, trebuie creat 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

A se vedea:

În cele din urmă, creez un fișier “telegraf.conf” cu următorul conținut:

+
Terminal

$ sudo docker-compose -f grafana.yml up

Pasul 3: Configurarea

Acum pot apela serverul, configura baza de date, crea tabloul de bord și conecta mai multe date de măsurare.
