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
目录:
- promettheus的搭建
- grafana的搭建
1.1、拉取prometheus镜像
搜索prometheus的镜像、选择Stars最多的镜像
sudo docker search prometheus
lugo@iZuf6gfo7g3452fkrhq8xwZ:~$ sudo docker search 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
lugo@iZuf6gfo7g3452fkrhq8xwZ:~/grafana$ sudo docker search grafana

2.2、启动grafana服务
sudo docker run -d --net=host -v /home/lugo/grafana/grafana_db:/var/lib/grafana -e "GF_SECURITY_ADMIN_PASSWORD=passwd" --name grafana grafana/grafana
