Grafana on platvormideülene avatud lähtekoodiga rakendus erinevate andmeallikate, näiteks InfluxDB, MySQL, PostgreSQL või Prometheus, andmete graafiliseks kuvamiseks. Täna näitan, kuidas paigaldada Grafana teenus Synology DiskStationile.

Samm 1: Synology ettevalmistamine

Kõigepealt tuleb DiskStationil aktiveerida SSH-sisselogimine. Selleks mine “Juhtpaneel” > “Terminal” > “Terminal”.


Seejärel saate sisse logida “SSH”, määratud pordi ja administraatori parooliga (Windowsi kasutajad kasutavad Putty või WinSCP).

Ma login sisse terminali, winSCP või Putty kaudu ja jätan selle konsooli hiljem avatuks.

Samm 2: Grafana kausta loomine

Loon Dockeri kataloogi uue kataloogi nimega “grafana”.


Käsklusega “cd” otsin Grafana kataloogi:
x
–
+
Terminal

$ cd /volume1/docker/grafana/

Seejärel loo ma Grafana kataloogi “grafana.yml” faili selle sisuga:

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_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:

Loon andmete jaoks veel kaks alamkataloogi:

x
–
+
Terminal

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

Kuna ma tahan Grafana ja sellega seotud liidese jaoks kasutada SSL-i, tuleb ikkagi luua sertifikaat:
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

Vt:

Nüüd käivitage Grafana server selle Compose-kutsega:

Terminal

$ sudo docker-compose -f grafana.yml up

3. samm: konfigureerimine

Nüüd saan ma serverisse helistada, andmebaasi konfigureerida, luua armatuurlaua ja ühendada rohkem mõõteandmeid.
