使用Grafana 呈現圖形化資料

Outline

使用 Grafana 連接 InfluxDB，呈現圖形化分析數據

What is Grafana & InfluxDB?

Grafana 是一個監控、分析數據，將資料圖形化的平台

InfluxDB 是一個時序型(Time Series)的開源資料庫，廣泛用於儲存系統監控數據

在 mac 安裝 Grafana

$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" // 使用Homebrew安裝，若電腦已經有Homebrew，則可以略過
$ brew install grafana

// 安裝完成後的訊息
To have launchd start grafana now and restart at login:
  brew services start grafana
Or, if you dont want/need a background service you can just run:
  grafana-server --config=/usr/local/etc/grafana/grafana.ini --homepath /usr/local/share/grafana --packaging=brew cfg:default.paths.logs=/usr/local/var/log/grafana cfg:default.paths.data=/usr/local/var/lib/grafana cfg:default.paths.plugins=/usr/local/var/lib/grafana/plugins

$ brew install influxdb

// 安裝完後的訊息
To have launchd start influxdb now and restart at login:
  brew services start influxdb
Or, if you dont want/need a background service you can just run:
  influxd -config /usr/local/etc/influxdb.conf

InfluxDB 建立 Database 及 User

$ influx
Connected to http://localhost:8086 version v1.7.6
InfluxDB shell version: v1.7.6
Enter an InfluxQL query
> create user admin with password 'adminpass' with all privileges  // 建立帳號 admin, 密碼 adminpass ：擁有最高權限

InfluxDB Config located at /usr/local/etc/influxdb.conf

修改 InfluxDB Config and restart

[http]
  # Determines whether user authentication is enabled over HTTP/HTTPS.
  # auth-enabled = true //預設為false, 改為true

首先啟動 Grafana 及 influxDB

$ sudo brew services start grafana
$ sudo brew services start influxdb
$ sudo brew services stop grafana  // 這是中止Grafana服務的script
$ sudo brew services stop influxdb // 這是中止InfluxDB服務的script

Grafana 預設網址為http://127.0.0.1:3000
