状态监测 tcp_status加入到zabbix

1、编写监控脚本，上传客户端服务器/etc/zabbix/scripts/tcp_conn_status.sh ，注意脚本需要+x权限。
2、在客户端上的conf 文件中加配置段
vim /etc/zabbix/zabbix_agentd.d/userparameter_tcp_conn.conf
UserParameter=tcp.status[*],/etc/zabbix/scripts/tcp_conn_status.sh $1
3、客户端重启zabbix-agent.service
4、服务器端 测试zabbix_get -s 客户端ip -k tcp.status[established] 检查是否能连通
5、创建模板，名字为template tcp connetction status 隶属于templates 群组
6、创建当前模板下的监控项目 ，[closed listen synrecv synsent established timewait closing closewait lastack finwait1 finwait2] 键值tcp.status[listen] 定义应用集
7、设计模板图形 名称TCP STATUS ,然后添加入监控项 （上面11条）
8、主机 链接此模板。

图形乱码文件，找到zabbix 站点程序目录include/defines.inc.php 查看下realpath 字体文件目录，使用windows 的字体去替换这个目录内的文件。
