什麼是grafana
grafana 是一個開源的時序性統計和監控平臺，支持例如 elasticsearch、graphite、influxdb 等衆多的數據源，並以功能強大的界面編輯器著稱。
安裝grafana
1 下載
wget https://dl.grafana.com/oss/release/grafana-6.0.2-1.x86_64.rpm2 安裝
yum install grafana-6.0.2-1.x86_64.rpm
systemctl start grafana-server
systemctl enable grafana-server
grafana-server -v
grafana-server 監聽端口爲 30003 訪問 grafana-server
http://ServerIP:3000
默認用戶名密碼爲： admin admin4 添加數據源選擇 Prometheus
5 添加Dashboard 也就是給節點添加可視化頁面
點擊‘ + ’ 選擇Import 輸入模板ID 8919
6 修改json文件
json文件複製出來，然後修改我們想要的
替換主機名，$node 替換爲192.168.184.129:9100 （還記得我們的基於文件發現的配置嗎）
刪除一些不想要的大致是這樣的
