写在前面

作为一个后端运维，监控是最重要，必不可少的一项工作。工作中我一共用过两种监控，zabbix和prometheus。先谈谈这两种监控的工具的优缺点，基于本人使用后的感受，仅供参考

	zabbix	prometheus
数据库（性能瓶颈）	mysql、pg	tsdb
架构（后期运维）	c/s	不需要安装客户端
资料（友好程度）	老牌监控，网上资料多	小众监控，资料少，需要多看官方文档
对象（应用场景）	适合面向工具，适合做中间件、交换机等监控	适合面向服务，适合做链路监控
模板（工作量）	模板多	模板少
UI（逼格）	自带画图，简洁，支持grafana	自身丑，grafana原生支持，用grafana后很炫酷
规格	监控集群规模大了比较吃力，麻烦	轻松应对，服务自动发现

个人比较喜欢prometheus，给人感觉很青春，自己写exporter，每个监控参数都可控，出问题也能很快定位到。这里先记录下利用容器快速搭建监控

sudo docker pull prom/prometheus

1.2、启动prometheus服务

mkdir prometheus
cd prometheus
vim prometheus.yml

global:
  scrape_interval:     60s
  evaluation_interval: 60s

scrape_configs:
  - job_name: prometheus
    static_configs:
      - targets: ['ip:port']
        labels:
          instance: prometheus

sudo docker run -d -p 9090:9090 --net=host -v /home/lugo/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml --name Monitor prom/prometheus
-d:容器后台运行
-p:映射的端口
--net:网络模式，这里选择主机模式，与宿主机公用一个network的namespace
-v:将配置文件挂在出来
--name:container名字

2.1、拉取grafana镜像

选择stars最多的镜像
