[Linux] 安裝grafana並且添加influxdb監控

安裝grafana，官網提供了ubuntu的安裝包，直接進行安裝

wget https://dl.grafana.com/oss/release/grafana_6.5.1_amd64.deb
dpkg -i grafana_6.5.1_amd64.deb
update-rc.d grafana-server defaults 95 10
service grafana-server start

使用influxdb的http api添加數據和查詢數據

添加數據

while true;do curl -i -XPOST 'http://127.0.0.1:8086/write?db=sinamail' --data-binary "webface,ip=10.2.2.1,httpstatus=404 prototype=\"GET /favicon.ico HTTP/1.1\" `date +%s`000000000";done

查詢數據
curl -GET 'http://127.0.0.1:8086/query?pretty=true' --data-urlencode "db=sinamail" --data-urlencode "q=SELECT * FROM webface where httpstatus='404'"

添加grafana的influxdb數據源

查詢表數據繪製出折線圖
