采用插件node_export

部署node_exporter插件
[root@node1 ~]# mkdir /opt/monitor/
[root@node1 ~]# tar -xf node_exporter-0.17.0.linux-amd64.tar.gz -C /opt/monitor/
[root@node1 ~]# cd /opt/monitor/
[root@node1 monitor]# mv node_exporter-0.17.0.linux-amd64/ node_exporter/
[root@node1 monitor]# cd /usr/lib/systemd/system
[root@node1 system]# cat node_exporter.service

[root@node1 system]# systemctl restart node_exporter
[root@node1 system]# ps -ef | grep node_exporter

prometheus service端的配置
在promenteus.yml文件当中添加
- job_name: ‘node_exporter‘
static_configs:
- targets: [‘192.168.0.61:9100‘]

重启服务
systemctl restart prometheus
