有时候需要检测服务器的tcp连接状态，用zabbix就可以做到，形成图表，很方便查看。

在zabbix客户端操作
1、进入目录

 cd /etc/zabbix/zabbix_agentd.d/

2、添加配置文件

 vim zabbix-linux-plugin.conf
 UserParameter=linux_status[*],/etc/zabbix/zabbix_linux_plugin.sh "$1" "$2" "$3"

3、添加zabbix_linux_plugin.sh脚本文件

 cd /etc/zabbix/
 vim zabbix_linux_plugin.sh

 }

main $1 $2 $3

4、给与脚本执行权限

 chmod +x zabbix_linux_plugin.sh

5、重启zabbix客户端

6、在zabbix web端导入模板文件

配置好模板后，就可以查看相关的信息了。
