grafana-prometheus-node-expoter

1.前言

服务器性能监控集成环境
grafana + prometheus + node-expoter

2.三个核心角色介绍

  • 1.node_exporter:
    在 9100 端口启动一个服务,自身抓取linux系统底层的运行状态数据,例如:cpu状态、内存占用、磁盘占用、网络传输状态等,等待其他上层(例如:prometheus)服务软件抓取.

  • 2.prometheus :
    从部署在不同服务器的多个 node_exporter 提供的服务端口 9100 主动获取数据,存储在自带的数据库 TSDB.

  • 3.grafana :
    提供可登陆的数据展示系统,从 prometheus 提供的接口获取数据,可视化呈现服务器性能指标。
    效果图

3.三个核心角色配置


#1.node_exporter 
    如果服务器比较多,就会有很多个 node_exporter 节点.  
    在多个业务服务器,你可以手动安装 node-expoter 容器、启动, 
    然后将ip、端口配置在 prometheus 配置文件中即可    

# 2.prometheus

    参见 prometheus_config/prometheus.yml 文件,有详细的配置示例

# 3.grafana
    # 必须设置权限,否则 grafana 启动报错
    为挂载的数据目录设置权限,相关的目录请参考 grafana 配置文件的 volumes 选项指定的路径
    chmod  777  -R  /home/data/project2021/grafana

4.快速部署本项目

    # 1.安装 docker 环境,如果没有docker环境,请先百度一下,安装。
    # 2.安装 docker-compose 环境,如果没有 docker-compose 扩展,参考 http://github.com/docker/compose/
    # 3.下载/克隆 本项目到你服务器的某个位置,在 docker-compose.yml 同目录执行  docker-compose  up -d 即可
