  - - docker-compose-prometheus.yml
    - prometheus.yml
  - 三、访问
  - - 1、exporter
    - 2、prometheus
    - 3、grafana
  - 四、Grafana配置
  - - 1、新增Prometheus数据源
    - 2、导入Prometheus Dashboard

一、前言

本文将基于以下环境通过Prometheus+Grafana建立Liunx系统的监控

Docker version 20.10.5, build 55c4c88
docker-compose version 1.28.6, build 5db8d86f
CentOS Linux release 7.6.1810 (Core)

二、docker-compose部署Prometheus+Grafana

# 环境准备
git clone https://gitee.com/zhengqingya/docker-compose.git
cd docker-compose/Liunx
# 注：
# 1. `docker-compose-prometheus.yml` 需修改grafana中配置的mysql连接信息
# 2. `prometheus.yml` 自行配置
# 运行
docker-compose -f docker-compose-prometheus.yml -p prometheus up -d

这里再展示下相关文件吧
