Centos 7 zabbix 实战应用
实际需求：公司已经有了100台服务器，现在需要使用zabbix全部监控起来。先出个方案（规划）
常规监控：cpu，内存，磁盘，网卡问题：怎样快速添加100台机器
方法1：使用克隆的方式
方法2：自动注册和自动发现
方法3：调用zabbix api接口curl 、python
开发自己的运维平台兼容zabbix的通道
方法4：服务监控，url监控等特殊监控：自定义监控
具体的实施步骤
全网监控技术要点分析
考试目标：使用zabbix将期中架构所有集群监控
具体内容：
一、硬件、系统、网络监控
所有集群节点（所有虚拟机）都监控上
交换机，路由器监控（简单方法：换成端口对应服务器网卡流量监控；标准方法：监控交换机的网卡）
snmp监控
二、应用服务监控
监控备份服务器，简单方法是监控rsync端口，如果有其他更佳方案可以说明；
方法1：监控873端口net.tcp.port[,873]
方法2：模拟推送拉取文件
监控NFS服务器，使用监控NFS进程来判断NFS服务器正常，如果有其他更佳方案可以说明；
方法1：端口（通过111的rpc端口获取nfs端口） net.tcp.port[,111]
方法2：showmount -e ip|wc -l
监控MySQL服务器，简单方法监控mysql的3306端口，或者使用zabbix提供的Mysql模板，如果有其他更佳方案可以说明；
方法1：端口（通过3306的mysql端口） net.tcp.port[,3306]
方法2：mysql远程登录
方法3：使用zabbix agent自带的模板及key
监控2台web服务器，简单方法监控80端口，如果有其他更佳方案可以说明；
方法1：端口（通过80的web端口） net.tcp.port[,80]
方法2：看网页状态码、返回内容==zabbix 自带WEB检测
监控URL地址来更精确的监控我们的网站运行正常；
监控反向代理服务器，PPTP服务器等你在期中架构部署的服务。nginx，pptpntp 端口udp 123
监控Nginx的7种连接状态。
在web下操作查看nginx状态信息
[*] location /status { 查看Nginx的一些状态信息
[*] stub_status on;
[*] access_log off;
[*]}

在zabbix-agent配置文件中添加key
[*]vim /etc/zabbix/zabbix_agentd.d/userparameter_nginx_status.conf
[*]UserParameter=nginx_active,curl -s 127.0.0.1/status|awk '/Active/ {print $NF}'
[*]UserParameter=nginx_accepts,curl -s 127.0.0.1/status|awk 'NR==3 {print $1}'
[*]UserParameter=nginx_handled,curl -s 127.0.0.1/status|awk 'NR==3 {print $2}'
[*]UserParameter=nginx_requests,curl -s 127.0.0.1/status|awk 'NR==3 {print $3}'
[*]UserParameter=nginx_reading,curl -s 127.0.0.1/status|awk 'NR==4 {print $2}'
[*]UserParameter=nginx_writing,curl -s 127.0.0.1/status|awk 'NR==4 {print $4}'
[*]UserParameter=nginx_waiting,curl -s 127.0.0.1/status|awk 'NR==4 {print $6}'
用awk 取这7种状态
在zabbix-server web界面操作
