1. prometheus-添加监控linux服务器
-
prometheus添加监控linux服务器
- node_exporter:用于监控Linux系统的指标采集器。
- 常用指标:
- CPU
- 内存
- 硬盘
- 网络流量
- 文件描述符
- 系统负载
- 系统服务
- 数据接口:http://IP:9100
- 使用文档:https://prometheus.io/docs/guides/node-exporter/
- GitHub:https://github.com/prometheus/node_exporter
-
安装部署
-
下载node_exporter包
https://github.com/prometheus/node_exporter/releases/download/v1.1.2/node_exporter-1.1.2.linux-amd64.tar.gz
-
监控端主机下载
[root@VM-0-17-centos ~]# wget https://github.com/prometheus/node_exporter/releases/download/v1.1.2/node_exporter-1.1.2.linux-amd64.tar.gz

-
在Prometheus配置文件添加被监控端:
-
验证prometheus配置文件
-
验证发现已经有数据了
-
-
使用Grafana展示node_exporter数据指标,仪表盘ID:9276
-
导入仪表盘
-
添加
