Redis集群下过期key监听的实现代码

安装grafana，官网提供了ubuntu的安装包，直接进行安装

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添加数据和查询数据

添加数据

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

查询数据

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数据源

查询表数据绘制出折线图
