Prometheus监控linux及windows服务器操作文档
安装及部署
Linux系统需要的安装包是node_exporter，安装非常简单，只要解压并配置服务文件启动即可，默认端口是9100
上传安装包到需要被监控的系统上/opt目录，并解压
[root@prometheus system]# cd /opt/
[root@prometheus opt]# tar -xvf node_exporter-1.9.1.linux-amd64.tar.gz
node_exporter-1.9.1.linux-amd64/
node_exporter-1.9.1.linux-amd64/LICENSE
node_exporter-1.9.1.linux-amd64/NOTICE
node_exporter-1.9.1.linux-amd64/node_exporter
[root@prometheus opt]# mv node_exporter-1.9.1.linux-amd64 node_exporter
[root@prometheus opt]# ls -ltr node_exporter

创建服务文件，让node_exporter启动起来
[root@prometheus opt]# cd /etc/systemd/system
[root@prometheus system]# vim node_exporter.service
