状态页面信息详解：
| 状态码 | 表示的意义 |
|---|---|
| Active connections 2 | 当前所有处于打开状态的连接数 |
| accepts | 总共处理了多少个连接 |
| handled | 成功创建多少握手 |
| requests | 总共处理了多少个请求 |
| Reading | nginx读取到客户端的Header信息数，表示正处于接收请求状态的连接数 |
| Writing | nginx返回给客户端的Header信息数，表示请求已经接收完成， 且正处于处理请求或发送响应的过程中的连接数 |
| Waiting | 开启keep-alive的情况下，这个值等于active - (reading + writing)， 意思就是Nginx已处理完正在等候下一次请求指令的驻留连接 |
环境说明：
| 系统 | 主机名 | IP | |
|---|---|---|---|
| centos8 | nginx | 192.168.10.141 | nginx zabbix-agentd |
| centos8 | zabbix | 192.168.10.143 | LAMP zabbix-server zabbix-agentd |
