2.4 修改Prometheus 配置，监控Linux机器
2.4.1修改Prometheus配置
进入Prometheus的安装文件夹，打开Prometheus配置文件
[root@master prometheus]# pwd
/usr/local/prometheus
[root@master prometheus]# ls
console_libraries NOTICE
consoles prometheus
data prometheus.yml
LICENSE promtool
[root@master prometheus]# vim prometheus.yml
在scrape_configs标签下，添加以下内容，配置监控
- job_name: 'Linux'
static_configs:
- targets: ['192.168.72.139:9100']
labels:
instance: Linux
2.4.2重启访问
[root@master prometheus]# systemctl restart prometheus
